    I am having issues with my desktop computer. The internet connectivity seems to go in and out as I'm working. It's almost like a glitch in service. It always comes back with in seconds but is very inconvenient. I have the lap top next to me as well, to check if the service is going out on that at the same time. The lap top stays connected the whole time. I just used the ping command to check my LAN card on the desktop and it reads Sent 4 Received 4 Loss 0. Which is good according to what I see online. Anyone have any suggestions as to what could be the problem? Any ideas great appreciated.
    Thank you!

    the desktop is connected directly to the router by cable
    and the laptop by wireless or also cable

    is that correct

    try changing to google open dns

    ------------------------------------------------------------------------


    Google public DNS
    Note using google public DNS servers from outside the US may actually slow performace - so use the following as a test to identify DNS issues - if these resolve the issues , then we need to investigate further to optimise the use of DNS


    Google public DNS
    http://code.google.com/speed/public-dns/

    Theres also a link on how to setup those DNS IP address up on a PC
    http://code.google.com/speed/public-dns/docs/using.html

    How to set XP here
    http://techie-buzz.com/how-to/google-public-dns-on-win7-and-winxp.html

    Then once you have set up those DNS entries

    Flush & register DNS

    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 commands:

    Ipconfig/flushdns
    ipconfig/registerdns


    If you receive the message
    The requested operation requires elevation.
    Then please open the command prompt as administrator
    Start> All Programs> Accessories and then right click on Command Prompt, select "Run as Administrator" to open a command prompt.

    now type the command again

    Show for both PCs and tell us which is which if it is not obvious ...

    Please attach a screen shot of the Networks page (don't collapse the Radar, Connection or Signal History) of the Xirrus Wi-Fi Inspector. If you need help with that see TSG Posting a Screenshot. FWIW to take screen shots with Windows 7 or Vista I prefer to use the built-in Snipping Tool.
