    My HP desktop connection is fine (obviously) but when I boot up my Compaq laptop, it says no WLAN connection available. Worked just fine last night when I turned off the laptop. I've disconnected power from modem with no results. The desktop is wired to the modem but the laptop is wireless. I've gone to the control panel and tried to connect that way but no luck. Don't have any buttons to push (I think) to enable or disable WLAN...

    you should have , maybe a combination of FN and one of the F keys
    or there maybe a switch somewhere
    and often a light is on for wireless - these vary in colour HP tended to use Blue and I think Compaq orange but that may have changed now

    whats the exact model of the compaq

    lets also see a xirrus screen shot and an ipconfig /all


    ------------------------------------------------------------------------
    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.
