    I recently set up our new Cisco Linksys E1000 router (we originally had a Belkin, but it is dying). It works perfectly fine on my desktop. However, there is only a "local connection" on my mom's laptop, a Toshiba Satellite running Vista. Diagnosis: Cannot Communicate with Primary DNS Server( I've read a bunch of other posts on many websites but so far nothing has helped. I'm not THAT good with computers, so you will have to help me step by step. Willing to give extra info. Please help, my mother is driving me crazy! :eek:

    Quick question so we can clarify.
    Your system is connected and happy.
    How does your mums connect. By wifi or Ethernet?

    See your mums laptop is going to need to use the same DNS as you. Not sure why she has directly in her DNS settings but, in a home environment we would put that in the modem, and then tell any computer the modems ip address.

    So config modem, add your DNS etc there.
    On your machine and your mums, set to automatic or assign your preferred ip, make sure gateway & dns are the modems ip address eg

    When you send a request to say google, it goes to your modem, which then goes to the DNS who then returns the ip that resolves www.gooogle.com

    Have fun

    Check your network card to see if its an Atheros brand.

    To do that, go to the Control Panel > Network and Internet > Network and Sharing Centre > Change Adapter Settings.

    Toshiba uses/used Atheros branded wifi adapters where a particular model was notorious for not working correctly.

    Does the Vista have the trouble with ethernet, Wi-Fi, or both?

    Open a (black) Command Prompt window:
    Hold the Windows logo key and press r; in the Run box type cmd and click on OK.

    Type the following command:


    [Note that there is no space between the slash and ALL.]

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    If necessary use a text file and removable media to copy the results to a computer with internet access.
