    I have a Dell Inspiron Desktop computer which runs windows vista and is about 2 years old now. It's always played up in the winter, usually because the room it is in is so cold! However, since we had a radiator installed it has worked fine.

    However, the internet connection has never been strong in that room, despite it being a floor above my wireless belkin router. It only ever has 3 or 4 bars, but this has never seemed to cause a problem. It has some "stick" (apologies for the awful tech language!) which screws into the back to allow it to connect to wireless networks. I don't always use it as it takes a while to boot up so it hasn't been used for a few days. I turned it on and it wouldn't connect to my network. I right clicked to view all networks to manually tell it to do it, but there are no networks shown when I know that I usually get a list of around 6! I clicked on the "diagnose problem" button and get a message saying: "The network adaptor broadcom 802.11g network adapter is experiencing driver or hardware related issues". Does this mean this "stick" needs an update? If so, how the hell am I supposed to update it if I cannot connect to the internet?!:confused::mad:

    Any help will be greatly appreciated! xx

    thats the aerial

    the following will need another PC connected to the internet so you can copy things over to help us diagnose the issues

    can we see ipconfig /all - device manager and xirrus screen shot


    ------------------------------------------------------------------------
    ipconfig /all
    If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post results here

    We would like to see the results from ipconfig /all post back the results in a reply here

    Hold the Windows key and press R, then type CMD then press Enter to open a command prompt box (A new dialogue box - black with white font, will appear on screen ):

    In the command prompt window that opens, type the following command:

    Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

    ipconfig /all > network.txt & network.txt

    It will export the results to notepad and then automatically open notepad.

    Now all you need to do is copy and paste those results to a reply here
    to do that:
    From the notepad menu - choose Edit - Select all
    all the text will be highlighted
    Next
    From the notepad menu - choose Edit - Copy
    Now go back to the forum - reply and then right click in the reply box and paste
    ------------------------------------------------------------------------

    ------------------------------------------------------------------------
    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/Products/Wi-Fi-Inspector.aspx
    Direct link to the program is here http://wpc.475a.edgecastcdn.net/00475A/XirrusWiFiInspectorSetup.1.2.0.exe

    {If the above link does not work heres another link http://www.pcworld.com/downloads/file_download/fid,77196-order,4/download.html}

    Then run and install the program - on a wireless enabled PC/Laptop
    if you get an error - You need NET Framework installed for the WiFi Inspector to function.

    Run the program

    A user guide is available here http://www.xirrus.com/Products/Wi-Fi-Inspector/xirruswifiinspectorguide1-2-0.aspx

    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.
    To upload it to the forum, open the full reply window and use the Manage Attachments button to upload it here.
    Full details are here http://library.techguy.org/wiki/TSG_Posting_a_Screenshot

    Note:
    For a reliable (or robust as the Xirrus user guide says) wireless connection you need a signal of about -70 dBm or better.

    If you are using the Mac OS then use http://www.istumbler.net/

    ------------------------------------------------------------------------
    Device Manager
    Post back the results in device manager
    If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC

    windows key and pause Key should open to allow device manager to be seen on laptops may need to use windows key + FN key + Pause Key
    if not then

    Start > control Panel {Vista set to classic view}> system > {Vista, device manager on left hand side} {XP hardware Tab, device manager button} >
    windows 7
    start > control panel> System and Security> Device Manager

    network adaptors, click on the + > post back the devices listed there
    are there any ! ? or X


    post a screen shot of the device manager - network adapters

    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.
    To upload it to the forum, open the full reply window and use the Manage Attachments button to upload it here
