    can you connect by cable and see if that works
    make sure you have the correct password
    log into the router and remove the password for the wireless and see if you can now connect

    post back an ipconfig /all 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
    Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.


    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/

    Whats the Router make and model

    you using a fixed IP for the ethernet
    which is interesting

    any other PCs connect to the router with wireless - just wondering if DHCP is not working

    you could try removing all wireless profiles
    also you could setup ethernet to be automatic dhcp - see if that then connects ok

    maybe try fixed IP on the wireless connection
    set to
    IP Address. . . . . . . . . . . : 192.168.1.50
    Subnet Mask . . . . . . . . . . . : 255.255.255.0
    Default Gateway . . . . . . . . . : 192.168.1.1
    DNS Server primary .............: 8.8.8.8
    DNS Server Secondary ........: 8.8.4.4

    you can use the same box to set the IP and DNS - just choose to set rather than automatic

    How to remove Wireless Profiles - for Vista and Windows 7
    http://mgmcc.forumotion.net/networking-tutorials-f17/removing-an-existing-wireless-profile-t109.htm
    - Vista/Windows7:
    - delete the wireless profiles
    Start> control Panel> classic view> network and sharing center> manage wireless networks

    Delete the profiles
    you will then have to enter the wireless security key for any networks you connect to - so make sure you know the correct password , and not using an incorrect password at all
