    Hi,

    I'm having a problem with my USB wireless network adapter. I'm not sure whether the operating system is the problem. Basically what happens is the adapter will disconnect every now and again (a few times a week), and I can't reconnect to any network until I disable the adapter and then re-enable it. This isn't just a problem limited to my PC, my laptop does the same thing and my girlfriend's laptop too, and a few other people I've asked who use wireless adapters.

    As this seems to be such a common problem, I suppose what I really want is just to know why this happens? Is it limited to Vista and Windows 7 or is it to do with the adapters themselves?

    Thanks!

    can we see the following when its connected OK and also repeat all the tests when disconnected - see below
    also lets see what the wireless environment looks like- post back xirrus - see below

    is this with your adapter or when connected to your router or just a generic statement - a little more detail would help

    ------------------------------------------------------------------------
    {run Xirrus Wi-Fi Inspector} Download and install
    If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC

    http://www.xirrus.com/library/wifitools.php
    Direct link to the program is here http://www.xirrus.com/library/wifi_download_redirect.php
    Then run and install the program
    if you get an error - You need NET Framework installed for the WiFi Inspector to function.

    Run the program

    post a screen shot of the program running - if there are a lot of networks showing can you click on "networks" top lefthand area - so we can see all the network information, and also post which network "Adapter Name" (1st column) is yours on the list

    To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.

    I get this problem at home daily. But after 5 minutes, it gets reconnected.

    Something on the router is causing a service on it to go into and endless loop (I think,) and then it has to restart the service and get back to functioning as a whole again.

    You can upgrading your routers firmware which may alleviate most of the problem. You can even update the adapters driver, do all the necessary windows updates. If those don't fix the problem, continue reading.

    An idea that might prove to be true, is that the wireless router is older than your fastest wireless network adapter (when talking about multiple connections.)

    You can't keep changing routers every time, but you can make sure that the router is as fast as the fastest wireless adapter (as a test) by buying the wireless adapter that matches the speed of the wireless router.
