Wireless Printer



Having a wireless network printer has several benefits. There is the obvious benefit of not needing wires to connect to the printer. While it is possible to share a printer via a network connection, having a wireless printer connection adds flexibility to the network. In a traditional computer sharing the printer, the host computer for the printer would need to be turned on in order to use the printer. You do not have this restriction with a wireless network printer.

Wireless Printer Adapter

A wireless printer adapter is a device which allows your printer to be linked on a wireless network. The printer involved will need to be a USB printer. The most common technology used with wireless printer adapters is Bluetooth. There are a variety of adapters available, depending on the needed range and number of computers needed to network with the printer.

Setting up a wireless printer

Adding a printer to a wireless network is the same as adding any other device. You will need to have a wireless printer adapter which is compatible with your printer. Generally speaking, you will need a USB printer. If your printer comes with a built in wireless Ethernet adapter, then you will not need to use a wireless printer adapter You will need to use a wireless print server to connect to the rest of the network..

Wireless Inkjet Printer

Almost any printer can become a wireless printer. If your printer has a USB connector, there are several wireless printer adapters that you can purchase that simply plug into the printer and you are instantly on the wireless network!

DSL Report Tools







DSL reports tools is used to monitor the history of internet usage. These tools generate the DSL session reports (for example Start Time, Duration, Accumulated Duration, Used Bytes Accumulated Used Bytes, Caller ID and user IP Address) to solve end user problem and to improve the DSL services. Many DSL providers offer free report generator tools with their internet service. These tools can be used on both ends (user end and ISP). These tools can also monitor the user internet web pages history, messenger sign in history and errors detail.

There are many DSL providers offers free speed test reports software with Internet connection package to check speed frequently and this speed test software generate the full month speed history. Many third parties software provider companies offer free speed check software on internet, download and use it to monitor speed constantly. Yon can test speed using any website for this purpose, search speed test tools websites using any search engine.  DSL speed test result will be different in different times, may be fast during early morning and slow at peak hours. You should get the results in different hours then with the help of average decide about the actual speed.

DSL vs. Cable




Cable Internet Line basically a dedicated line used to access the internet with high speed and provides the faster internet access as compare to DSL and dial-up. Its data transmission speed is start from 64 Kbps to 30 Mbps. But DSL also provides high speed on already exiting telephone lines and same time you can use internet and as well as your line for phone. In DSL, both ends of connections require the network cards and DSL modems for data communication.
There are some advantages and disadvantages of both technologies. There are many factors that you should consider when going to decide to get DSL connection or Cable Internet like connection speed, security, installation fees and monthly rates. But this is very rare chance both services are available in your area. The cable provider in my area might be different from yours, hopefully these tips will help you understand what to look for.
 
Consider a little comparison between DSL and cable that will help you to choose more suitable internet connection in your area.
  DSL Internet Connection                                       
  • Its data transmission speed start from 128 Kbps up to 10 Mbps.
  • DSL is dedicated connection not shared with other internet user.
  • DSL monthly rates are between 50$ to 100$.
  • Your internet speed will depends upon the distance between your home to DSL provider.
Cable Internet Connection
  • Its data transmission speed is start from 64 Kbps to 30Mbps.
  • Cable internet is not a dedicated connection but shared with other internet user.
  • Cable monthly rates are between 30$ to 60$.
  • No distance matter with Cable connection between your home to Cable provider.

USB 2.0 - Hi-Speed USB

 
As an aside, USB mice and keyboards need only 1.5Mbits/s to function. That performance level is also named 'USB' by the USB Promoter Group.

To sum it up, USB 2.0 specification incorporates three speeds: Hi-Speed, Full-Speed and Low-Speed. You as a consumer don't need to figure out all the jargons. Just keep in mind that only 'Hi-Speed USB' and 'USB' host and devices exist.

How do I know if my PC has USB 2.0?
You can identify whether your PC has Hi-Speed or not relatively easy. Open Device Manager and expand the Universal Serial Bus section. There should be an "Enhanced" USB host controller present.

Windows 98 systems may use a different name, because Hi-Speed USB drivers in these operating systems are not provided directly from Microsoft (Windows ME, 2000 and XP get their drivers through Windows Update).

These drivers are provided by the manufacturer, and may carry the maker's name (i.e. ADS, Belkin, IOGear, Siig, etc.). There should also be two standard version USB host controllers present as well. They are embedded in the USB chip which routes the differing USB speeds accordingly without user intervention.

There are currently 6 manufacturers of the Hi-Speed USB host silicon themselves:
  • ALi (Acer Labs)
  • Intel
  • NEC
  • SiS
  • VIA
  • nVidia (shows as "Standard" controller
Any other brand name that appears in Device Manager would likely be an add-in Hi-Speed USB PCI card. The makers above do not make add-in cards, but they do make the chips that are used in them.
How do troubleshoot "unknown device" error listed in Device Manager?
  • The USB device or the USB adapter requires its own power source. If your USB device or adapter came with an AC power "brick", try connecting it.
  • Here's a likely one - the front USB ports on your PC case may be misconnected. I've seen them that way from the factory. It's a good idea to check the connections against specifications. The standard order of connection is Red, White, Green, and Black. No more than 4 wires per USB bank are needed.
  • Defective device. Do not assume that all PC components work correctly out of the box. I've seen many new USB devices that do not work. If you can, try the device on another PC.
  • All drivers are not installed. Some devices will require installing the driver package before plugging in the device. Some devices will also require basic USB files from the Windows CD before the unit will function. The general rule is to always follow installation directions precisely and to have the Windows CD ready.
How fast is USB 2.0?
USB 2.0 has a raw data rate at 480Mbps, and it is rated 40 times faster than its predecessor interface, USB 1.1, which tops at 12Mbps. Originally, USB 2.0 was intended to go only as fast as 240Mbps.
How will consumers benefit from USB 2.0?
With speed 40 times more than that of USB 1.1, USB 2.0 broaden the range of external peripherals that can be used on a computer. Even with multiple high-speed peripherals connected to a USB 2.0 bus, the system will less likely to hit the bandwidth bottleneck. The new specification also inherits the current USB's Plug and Play and hot-swapping capability as well as providing backward compatibility for USB 1.1 hardware, allowing existing user base to upgrade seamlessly.
Do USB 2.0 & USB 1.1 hardware work interchangeably?
You may have heard that USB 2.0 is "backward-compatible" with USB 1.0/1.1 (Full-Speed USB). While that's true, USB 1.1 is also forward-compatible with USB 2.0. Whenever a system has USB 2.0 ports, you'll find the "Enhanced" USB controller in Device Manager, but you will also find two other USB controllers. These two to maintain backward compatibility to USB 1.1 devices. Each USB 2.0 host actually has 3 chips onboard. The USB controller routes signals to the correct controller chip depending on how a device is recognized. Where a device is physically plugged in has no bearing on how it is routed. All ports on a USB 2.0 motherboard can host any USB devices at all as long as the system and devices are healthy.

The vast majority of USB 2.0 devices will work on older PCs and Macs. None should flat-out fail unless there are other issues with the system. Hi-Speed USB devices will revert to Full-Speed operation when connected this way. Understand that Hi-Speed is at least ten times faster than Full-Speed in actual operation, so the speed difference is quite noticeable - unless you have never experienced Hi-Speed, of course.

When it comes to USB hub compatibility between USB 2.0 and USB 1.1, here some facts:
  • A powered hub is always preferable to unpowered.
  • USB hub ports are not as capable or flexible as real PC ports so it's best not to expect the world of them.
  • USB 1.1 (obsolete) hubs will work fine on USB 2.0 ports, but they cannot utilize USB 2.0 capabilities. They will default to slower speeds.
  • Hi-Speed and Full/Low-Speed USB devices can coexist nicely on USB 2.0 hubs. Connecting such a hub to a USB 2.0 port is recommended.
  • USB 2.0 hubs can be used on older USB 1.1 computers.
  • Although it is said that you can "cascade" up to 4 hubs, problems may start to arise after two hubs, it's best to minimize hub usage if possible.
  • Many USB devices don't work well on hubs. Cameras, scanners and especially USB drives are known to have problems with hub connectivity.
  • Remember that "active USB extensions" are really just one-port hubs.
Will USB 2.0 replace USB 1.1?
Not entirely, because many products such as generic keyboards, mice, joysticks and audio speakers do not require the faster speed of the new USB 2.0 technologies. Only bandwidth-hungry devices, such as web cams and high-capacity storage systems, will need all the speed. However, next-generation systems will come with USB 2 ports rather than USB 1.1.
How do I distinguish between a USB 2.0 and a USB 1.1 devices? New logos designed by the USB Promoter Group allow consumers to easily identify the new USB 2.0 products. The new colorful logo for USB 2.0 is labeled USB Hi-Speed, and the new logo for USB 1.1 is labeled with USB Basic Speed. However, most people won't miss it as manufacturers often label USB 2.0 READY Or 40 times faster than USB 1.1, on the boxes.
Will USB 1.1 devices run any faster on a USB 2.0 bus?
No. However, the new USB 2.0 archiclecture allows more high-speed USB 1.1 devices, such as web cams, audio devices, to share the bandwidth. Developers need to follow USB 2.0 spec in order to design higher speed peripherals that can take advantage of the extra bandwidth. USB 1.1 devices still operate at 12Mbps at full-speed and 1.5Mbps at low-speed on a USB 2.0 bus. Even though USB 1.1 devices won't run any faster, they can work alongside of USB 2.0 devices on the same bus.
What are USB Hi-Speed and USB Basic Speed logos?
These logos are part of USB Promoter Group's branding program that ensures the quality of USB products. The USB 2.0 certified products would display a blue, white and red logo, bearing the words Certified and Hi-Speed. The classic USB 1.1 certified products would display a black and white logo with the words USB and Certified.
Under a license from USB-IF, products must pass the compliance tests before manufacturers can use one of the two trademarked logos. The Promoter Group will take legal actions on manufacturers that label either logo on their products, which have not passed the tests.
What happen if a USB 2.0 devices are plugged into a USB 1.1 systems?
The entire bus under the USB 1.1 root hub will slow to 12Mbps. The operating system will probably notify the user about the sub-optimal configuration and recommend for a better course of action.

If several USB 1.1 hubs are connected to a USB 2.0 bus, then each of the USB 1.1 hubs will get a full 12Mbps bandwidth.
What is the max? Length of a USB 2.0 cable?
5m. however, if you cascade 5 hubs with 5m USB cables, this will allow you to connect a device 30m away.
What do I need to use a USB 2.0 device?
The requirement is similar to that of USB 1.1, but all components will have to be USB 2.0 compliant. A successful USB 2.0 connection requires a USB 2.0 host controller card, a USB 2.0 driver and a USB 2.0 peripheral.
How much will it cost to upgrade to USB 2.0?
Around $80 to $150. Currently, Orange Micro., Adaptec and IO Gear are shipping USB 2.0 PCI cards, some of which even have FireWire ports. Interestingly, almost all USB 2.0 PCI cards include an internal port, which is probably for connecting internal USB 2.0 IDE enclosure or USB 2.0 front panel.
Will USB 2.0 arrive on mobile computers?
Yes, but not in integrated solution on laptops. You will need a USB 2.0 Card Bus card. Orange Micro. is shipping USB 2.0 compliant 4-port Card Bus card. Eventually, notebook vendors will adapt to USB 2.0 technology, and we will see USB 2.0 ports on laptops. This transition won't happen until 2002 at the earliest.
Which operating systems support USB 2.0?
Microsoft has released the official USB 2.0 driver for Windows XP and Windows 2000. The version is 5.1.2600. The software is available on-line at Windows Update website. (If you don't have a USB 2.0 card installed in your system, Windows Update won't list the USB 2.0 driver as an update.)

The software company is still considering USB 2.0 support for Windows ME, but it already has decided not to bring USB 2.0 to Windows 98 and Windows 98 SE. If you have Windows 98, you will have to rely on 3rd party USB 2.0 support from USB card manufacturer.

Do USB 1.1 cables work with USB 2.0 devices?
Ideally, yes. USB 2.0 architecture uses the same cables and connectors as USB 1.1 compliant products. Unfortunately, only 3 out of 11 cables on the market are certified as USB 1.1 compliant. You may run into the cables that cause problems connecting high-speed peripherals. To avoid negative user experience, most vendors include USB 2.0 compliant cables with their USB 2 PCI cards and peripherals.

Touch hardware and Windows 8

The Windows team has continued to work in lock step with external hardware partners to fully embrace the experience we want for Windows 8. New Windows 8 PCs are coming, and while that is not a topic for this post, we at Microsoft are excited with what our hardware partners have in store for you.
It’s worth reinforcing that Windows 8 will run on the hardware available today, and we are committed to making sure that happens. So you should feel confidence in installing the Consumer Preview on the machines that you own today. However, as much as we value compatibility, we also have to balance this with making Windows 8 really shine on new Windows 8 PCs. We’d like to provide you with some perspective on our efforts and how we will achieve this.

Making sure Windows 8 works on your Windows 7 PC

At the //build/ conference we introduced a set of touch interactions that make up the Windows 8 touch language. These core interactions form the basis of the Windows 8 user interface, and are reused heavily in the application frameworks within our common controls and samples. The primary goal of our touch language is to promote ease-of-use and ensure user confidence. By confidence, we mean that all touch interactions work consistently and reliably all the time. Developers who consume our controls will automatically feature this language in their applications when they re-use the common controls or use the samples, and in doing so, they also minimize any learning required for users.
Press and hold to learn, Tap for primary action, Slide to pan, Swipe to select, Pinch and stretch to zoom, Turn to rotate, Swipe from edge for app commands, Swipe from edge for system commands.
The touch language allows us to design a base user experience that is optimized for touch and works well on every PC, whether it was built originally for Windows 7 or for Windows 8. The fundamental gestures require no more than 2 fingers. However it is important to note that 2 fingers can be very limiting for a variety of applications. This is why Windows 8 PCs require digitizers that support a minimum of 5 fingers. The reason we went in this direction is a response to developer feedback. Developers do not want their creativity to be limited, and in particular, they let us know that they want to be free to use whichever multi-finger gestures or controls are useful. They do not want requirements for a minimum number of fingers that may not make sense for their application. As such, we focused on a minimum of 5 fingers to enable scenarios like whole hand interactions (all 5 fingers) or multi-finger/multi-hand scenarios. This will address the feedback, and unlocks opportunities for developers to push the envelope with multi-touch applications. So, while we ensure that the OS works well with a Windows 7 PC, a new Windows 8 PC is going to be much more consistent and predictable both from a user and developer perspective.
New UI concepts in Windows 8 also impact touch hardware design. This is another area where Windows 8 PCs will be more capable than existing Windows 7 PCs. For example, the edge swipe required to reveal the charms and app bars fundamentally changes all the assumptions made on touch hardware. Traditionally, the edges of the screen are where touch sensitivity drops off, and it’s a place that hardware manufacturers have traditionally not placed much emphasis on. The center of the screen received all the innovation, while the edges have suffered. If you have seen or experienced the Windows 8 user experience, the edge swipe is a critical part of using Windows. However, it also has a big role to play in our developer promise, as every pixel used to detect an edge swipe is a pixel taken away from the developer. For Metro style apps, where every pixel belongs to the developer, it is critical that we uphold and deliver on this promise.
We worked closely with our hardware partners to figure out a design that will allow all pixels on a touch screen to be accurate and perform well. There were many challenges here, but we were able to deliver on the promise of Windows 8 PCs that have the ability to trigger the edge swipe without taking any pixels from applications, and with extremely good edge sensitivity using touch—a promise that benefits developers and users alike. To make things work with Windows 7 PCs, we had to go in a different direction. In order to make edge swipe work consistently on Windows 7 PCs, we created a mode where there is a 20-pixel buffer to catch the edge swipe gesture. This allows a majority of PCs to reliably invoke the charms and use Windows 8 effectively. The downside of this buffer is that it takes away some real estate from the application, and from developers.
There is a broad set of Windows 7 PCs available in the market, and while this is a strong testament to the diversity of the Windows Ecosystem (as it offer more choices for our users), it also adds a degree of variance in touchscreen performance that must be accommodated. Here are some other examples of work we did to enable Windows 7 PCs to work well with touch:
  • Making gestures like press and hold and pinch to zoom more forgiving On some touch screens, the information reported from the screen is not consistent. We call this “jitter.”., When “jitter” happens, it’s hard for the system to know if the finger is actually moving or stationary. In some instances, a simple gesture like “press and hold” becomes extremely hard to calculate.
  • Determining user intent for sloppy or imprecise touches Although larger UI elements help improve touch targeting, we don’t have that luxury within the Windows desktop, especially with existing desktop applications. For this, we developed new ways to remap touch targets using the geometry of the finger, such that it becomes easier to invoke any UI that is within the radius of your finger contact. We will talk more about this feature in a separate blog post.
While you can see that there are a number of places where we’ve done work to accommodate the variance in hardware, there will be some areas where software cannot compensate. We will call out a few of them below. The good news is that in some cases users can learn to overcome these issues; in other cases, the experience will seem slow or imprecise, sometimes requiring you to attempt a gesture more than once before you succeed. We can overcome some of these issues with updated drivers, but this is entirely up to the hardware partners to evaluate and support. Here are some other examples of inconsistencies that we see when comparing touchscreens on some Windows 7 PCs:
  • Individual taps do not always work, especially when typing quickly in the touch keyboard.
    There are generally 3 things that impact this: the touch screen response rate, typing speed, and number of touch points. As you start typing faster on a touch screen, the screen has to match the speed of switching keys. The response rate in a touch screen is usually more optimized for detecting dragging gestures than rapid taps; this will manifest itself as missed taps. When you start typing faster, the chances of having more than 2 simultaneous fingers down also goes up. On systems that do not support more than 2 touches, you will notice missed touches.
  • Swipe to select is inconsistent on hardware that does not detect small touch deltas fast enough.
    It takes a little time for touch to respond to an initial touch. In some cases, the touch screen ignores the first few values of the initial touch, and the system then has difficulty interpreting the swipe correctly.
  • Swipe and slide can be misinterpreted as a tap, especially on hardware that is not sensitive enough.
    This stems from the same issues as above, in which touch screens take some time to respond, and cannot send a consistent stream of data once a swipe or slide begins. In this case, it can result in the system reading the data as taps instead of slides. When this happens, swiping and sliding more slowly may help.
  • Swipe from edge does not always work, especially with faster swipes.
    Although we have the buffer accommodation described above, fast swipes from the edge sometimes suffer from response rate as well. Fingers that come in too fast from the edge don’t get picked up by the touch screen until it is past the buffer. Trying again at a slower speed usually helps here.
Here is a video that shows some examples of how hardware can affect the Windows 8 touch language.

Note that touch variability does not necessarily block usage, since you can adapt the way that you touch or interact with touchscreens to work around different timing or movement thresholds. For example, if the charms don’t appear after an edge swipe, you can try again, but swipe more slowly. However, this variability does tend to make you less confident about using touch on Windows. However, we don’t want app developers to have to accommodate all the variances in touch hardware. Ultimately, we want to keep the promise of consistency, and the promise that applications work on all Windows 8 PCs. This is why we are working hard to ensure that Windows 8 PCs have a consistently good touch experience, and why you will want one of these new PCs when they are released.

Touch hardware testing

To make sure that the Windows 8 experience works well on your existing Windows 7 PC, we’ve been testing a bunch of them. Listed below are some of the newer Windows 7 systems that are commonly used within the Windows organization. This is not an endorsement, and users of these PCs should not expect official support from PC vendors when installing Windows 8.
  • HP Elitebook 2760p convertible
  • ASUS EP121 tablet
  • Dell Inspiron Duo convertible
  • Lenovo x220t convertible
  • 3M M2256PW 22” display
  • Samsung Series 7 slate
To support our commitment to customers who upgrade, we also frequently test Windows 8 on a broader set of in-market systems. We listed many of these systems in the previous post, and will now share some of the data we collected. Our test team collected data on how the Windows 8 touch interactions perform on 64 different Windows 7-era touch screens. As seen in the pie charts below, the data covers a variety of different form factors and touch sensor technologies.
Pie chart: Slate 14%, Monitor 16%, All-in-one 30%, Convertible 40%.Pie chart: Capacitive 66%, Optical 28%, Other 6%.
What we found was encouraging: the vast majority of Windows 7 touchscreens can be used with Windows 8. This means that touch drivers continue to load, and you can perform the basic touch interactions in Windows 8 with a reasonable degree of success. But, as described in the previous section, we did see significant variability in how touch interactions were interpreted across different Windows 7 touchscreens. For example, the same swipe gesture can be interpreted as selecting a tile on one touchscreen, as dragging it on another, and as activating (tapping) it on a third screen. The charts below show examples of how successful completion varied between touchscreens when performing Windows 8 interactions for swiping to select a tile, dragging a tile to move, dragging to resize a snapped view, and swiping the screen edge to invoke the charms. 100% means that all attempts succeeded (note that for Windows 8 PCs, we require all these tests to pass with at least 95% success*).
Chart showing test results for Tile Select on Windows 7 touch screens; Success rate is mostly between 80% and 100%
Test: Select a tile in Start
Expected result: Tile is selected with a single swipe

Chart showing test results for Tile Arrange on Windows 7 touch screens, Success rate is mostly between 80% and 100%, with a few data points around 65%.
Test: Move a tile in Start
Expected result: Tile is moved on first drag attempt

Chart showing test results for Snap View Drag on Windows 7 touch screens, Success rate is mostly between 70% and 95%, with a few data points around 55%.
Test: Resize a snapped application
Expected result: Application is snapped to new size

Chart showing test results for Right Edge Swipe (no mitigations) on Windows 7 touch screens, Success rate is distributed between 0% and 100%, with a few data points around 55%.
Test: Swipe the right edge to view Charms
Expected result: Charms bar appears on first swipe
* pass rates may vary between each test

The road to Windows 8 PCs

Throughout Windows 8 development, we worked closely with external hardware partners to reduce hardware variability and establish consistent Windows 8 requirements. At the time of the //build/ conference, we were still working with partners to establish these requirements in early prototypes. The Samsung slate that was handed out at //build/ was our first attempt to push new requirements into a production system. Those of you who had the opportunity to use the Samsung slate experienced a level of touch quality that is closer to what we expect for Windows 8. You’ll also find some of these improvements in the commercialized version of the same slate hardware, which Samsung calls the Series 7 slate. Experiencing Windows 8 on this hardware will give you an idea of what touch will be like on Windows 8 PCs.
We have published our requirements for new Windows 8 hardware, and we continue to work with touch hardware partners, suppliers, independent hardware vendors, and PC manufacturers to ensure that new devices meet the requirements. Microsoft tests and certifies each new touch device before it can enter the market as a Windows 8 PC. This is how we will ensure consistency and quality in touch hardware for Windows 8. We will talk more about the certification process in a separate blog post.

Experience the Windows 8 Consumer Preview

So if you have a Windows 7 touch-capable PC today, don’t hesitate to use the Windows 8 Consumer Preview and take advantage of the Metro style user experience that we’ve built. The core experience will work well, but you’ll need to be mindful of some of the issues we’ve covered above. On new Windows 8 PCs, these issues won’t be present.
If you don’t have a touch-capable PC, you can still experience the Metro style UI with a mouse and keyboard. Last and not least, if you develop applications for Windows 8, the developer tools include an emulator that you can use to simulate touch. It will give you a close approximation of how your application will work, and we encourage you to take advantage of it. We hope you agree that we’ve come a long way in ensuring that Windows 8 has the best touch experience. We’re excited to provide a way for you to be more hands-on with your PC.
Thank you!

Wireless Headset



The Best Wireless Headset

The best wireless headset for you will depend on your needs and how often you will use it. For a cell phone wireless headset, you will want to look for a blue tooth headset, as that is the industry standard. Other features to consider include:
  • Comfortable fit
  • Features you require
  • Within your price range
  • Compatible with your current cell phone.
If you need a wireless headset with a landline telephone, you need to consider some alternate options:
  • What brand name are you most comfortable with? Wireless headsets for your regular phone come from various manufacturers including Plantronics, GN Netcom and Polycom.
  • How much desk space you want it to take up?
  • How much range it needs to have (how large is your office)


You may not have considered it, but you can also get a headset for your computer. If you use Skype or any of the other nifty computer phone call programs, you may have a headset plugged into your desktop or laptop already, but wireless may make your life much more flexible.

Wireless Headset: Bluetooth
 Bluetooth is another wireless standard, mostly used for short range connectivity. You will often find Bluetooth technology in printers, cell phones and wireless headsets. Its range is significantly shorter then other wireless technology, about 30 feet. It is less expensive then other Wi-Fi standards and works well for many home offices. This is why Bluetooth has been included in many wireless headsets - but beware of that range, you don't want to wander too far from your source and lose you call.

Reasons to Use a Wireless Headset

A wireless headset offers you significantly more freedom while you talk on your cell phone or regular phone. By plugging in the wireless adaptor, you can walk all over your home or office. The benefits in an office environment are clear, but these are also great for stay at home parents who may be chasing an active toddler all over the house! The car is another obvious location for the use of a wireless headset.
Good wireless headsets come equipped with volume control and answer buttons and they should be small and fit comfortably over your ear. They should be snug enough so you don't have to worry about the headset slipping off your ear or falling to the ground.

Problems with Wireless Headset
If your wireless headset is having performance issues, there are a few things you can check.
  • Make sure your telephone or ell phone is within range and not overly obstructed.
  • Check to make sure your cell phone battery is charged and you are receiving a good signal.
  • Typically, with wireless headsets you will have multiple channels from which to select the best signal, so make sure that you have switched around to see which is best and that you aren't still on the default channel.
  • Make sure you try your phone without the headset on at all to ensure that the line or signal is strong.
  • Finally, check to make sure the batteries in the wireless headset are charged.

Wireless Headset
A wireless headset is a small device you slip over your ear that allows you to talk via your cell phone, but hands free. Using the blue tooth technology standard, wireless headsets offer an excellent range and great hands free features.
These wireless headsets have been especially popular with commuters and people who need to use their cell phones in their car. The increased safety afforded when you are using both hands to drive makes the investment in one of the headsets an easy decision. Additionally, you aren't hampered by an annoying cord which can also be hazardous if you need full range of motion to avoid a potential car accident.

Wireless Headset with Regular Phone 
There are wireless headsets on the market that you can use with a regular phone, but don't think you'll have to buy a different headset for every phone in your home or office. There are also wireless headset devices that you can hook up to a regular phone, cell phone and PDA, and you can alternate which device you wish to use your wireless headset with. This kind of flexibility is key in this day and age of telecommunications - and for your wallet.

WiMAX Wireless Broadband Info

WiMAX stands for World Interoperability for Microwave Access that enables the actual broadband wireless network with high speed. WiMAX operate same like WiFi but WiFi operate with some limitation like it is base band technology and cover only 100 feet radius with slow speed. WiMAX covers a radius of 50 Km and work with the speed of 70 Mbps. WiMAX is the replacement of the wired broadband. In wired broadband connection, we can transmit data with 512 Kbps to 10 Mbps speed and more, for example DSL broadband and cable broadband. In future all new desktop and notebook computers will be incorporated with WiMAX technology. With this technology you will be connected to the internet even you are driving your car with the speed of 120 Km.

How to recover PIX Firewall image using monitor mode?


Today tip will help you to install the IOS on the Cisco PIX firewall 501, 506, 506E, 515E, 515, 525 and 535 series. First make sure, you have installed and configured any TFTP (Trivial File Transfer Protocol) server over the LAN port. If you are trying to boot up your PIX firewall without an IOS, the nonworking firewall will boot up in ROM monitor mode, or turn the power switch off and back on to recycle the power then press you can press the ctrl and break keys simultaneously. The monitor> prompt is displayed and the firewall first prompt will look like this:
monitor>
Follow the step-by-step procedure to recover the IOS of Cisco PIX Firewall: 
First make sure, you have connected your PC to the Ethernet and Console port of PIX Firewall using any emulation software.
Now use the interface command to specify the interface of PIX Firewall use for traffic.
monitor>interface 1
0: i8255X @ PCI(bus:0 dev:13 irq:11)
1: i8255X @ PCI(bus:0 dev:14 irq:8 )
 
Now use the address command to assign the IP address of PIX Firewall interface.
 
monitor>address 10.1.1.1
address 10.1.1.1

Issue the server command to assign the IP address of the remote or TFTP server.  

monitor>server 131.200.1.1
server 131.200.1.1
Issue the gateway command to specify the gateway address through which the server is accessible.
monitor>gateway 10.1.1.5
gateway 10.1.1.5
Now issue the file command to identify the file name PIX firewall image.
monitor>file firewall-ios
file firewall-ios
Now use the tftp command to start the IOS recovery process of the PIX Firewall, and then following message will appear.
monitor> tftp
 
tftp firewall-ios@131.200.1.1 via 10.1.1.5....................................................

How to perform route summarization using BGP protocol?


Route summarization is the process of replacing a series of routes into a summary route with subnet mask. The main purpose of summarization is to decrease the uses of bandwidth and make the size of routing table smaller. For example if you are trying to advertise four routes 194.1.17.0/24, 194.1.18.0/24, 194.1.19.0/24 and 194.1.20.0/24 from router C to router B then the only summarized address as 194.1.16.0 255.255.248.0 will be advertised in the update packet.
Today tip will help you configure BGP route summarization between two different types of routing protocols. In this case, we will try to configure three different routers with routing protocols OSPF & RIP and then advertised one summary route from router C to router B using BGP Aggregate-address command.
Follow the network topology of three different class network in given figure:



.
Follow the network topology of three different class network in given figure:
Configuration to Enable OSPF & BGP on Router B
In global configuration Mode:
B (config) # router ospf  1 
(Enable ospf protocol and 1 is Autonomous number)
B (config-router) # network 40.0.0.0 0.255.255.255 area 0
(Advertised router B Serial Network 40.0.0.0)
B (config-router) # network 210.100.20.0 0.0.0.255 area 0
(Advertised router B Ethernet Network 210.100.20.0)
B (config-router) #redistribute bgp 20 subnet metric 50
(Redistribute bgp into ospf)
Now configure BGP on router B
B(config)# router bgp 20
B (config-router) # neighbor 61.1.1.2 remote-as 10
B (config-router) #end
Now run show command to display the BGP updates.
B #show ip bgp
Now verify the summarized route in router B routing table, run the command
B #show ip route
Configuration to Enable RIP & BGP on Router C
In global configuration Mode:
C (config) # router rip
(Enable rip protocol)
C (config-router) # network 210.100.30.0
(Advertised router C Serial Network 210.100.30.0)
C(config)#ip route 40.0.0.0 255.0.0.0 61.1.1.1
(Create a static route to router A to complete routing table.)
Now create four static routes and then advertised in BGP.
C(config)# ip route 194.1.17.0 255.255.255.0 null 0
C(config)# ip route 194.1.18.0 255.255.255.0 null 0
C(config)# ip route 194.1.19.0 255.255.255.0 null 0
C(config)# ip route 194.1.20.0 255.255.255.0 null 0
Now configure BGP on router C
C(config)# router bgp 10
C (config-router) # neighbor 61.1.1.1 remote-as 20
C (config-router) # redistribute static
(Advertised static routes)
C (config-router) # aggregate-address 194.1.16.0 255.255.248.0 summary-only
(summary of four static routes)
C (config-router) #end
Now run show command to display the BGP updates.
C #show ip bgp
Now verify the routes in router C routing table, run the command
C #show ip route
Configuration to Enable OSPF & BGP on Router A
In global configuration Mode:
A (config) # router ospf 1 
(Enable ospf protocol and 1 is Autonomous number)
A(config-router) # network 40.0.0.0 0.255.255.255 area 0
(Advertised router A Serial Network 40.0.0.0)
 A(config-router) # network 210.100.10.0 0.0.0.255 area 0
(Advertised router A Ethernet Network 210.100.10.0)
