    Hello there!

    You said you are able to ping to default gateway right? In your router does it detect the internet connection? Say some routers will have a light it detects it internet connection is active. Did you check once with AT&T to make sure you have a active internet connection?

    So let me know sure I understand you correctly. Desktop cannot ping the default gateway also cannot connect to internet.

    Laptop - Wireless - Can connect to internet without any issues

    Am I correct? If so the problem might be Default gateway. If you use 192.168.1.254 on the Desktop from a browser does it connect to ATT modem?

    I have doubts that it will help in this case but try setting your DNS to Open DNS. Since you have changed DNS address at least you will know that you have good addresses. Actually I recommend using Open DNS instead of an ISP DNS anyway.

    Open DNS addresses:
    208.67.222.222
    and
    208.67.220.220

    Open DNS:

    Correct, when connected to the repeater (ddwrt router) the desktop can communicate the repeater (ddwrt router) but it cannot ping the ATT router via the repeater.

    When I connect the desktop directly to the ATT modem/router I can communicate with the ATT router and access the internet.

    I can access the internet via the repeater (ddwrt router) with the laptop (wired). I also have the desktop wired to the repeater (ddwrt router) at the same time and I cannot access the internet with the desktop.

    Any ideas?

    Default Dns server is not responding, tried one solution already

    Hello to the wonderful people who shall finally help me fix my issue,

    My internet connection constantly shows limited for my Windows 8 Lenovo G500s series laptop. I went through these threads steps (FIX: DNS Server is not responding on Windows 7 / 8), and still, the problem persists. I did skip a few steps,

    3.Now you have to enter the same DNS address in Router configuration as well refer the router manual for more information.

    4.Try to Install and Configure OpenDNS and see if that helps


    , due to being clueless about how to achieve them. I need specific help, please, on how to solve this annoying issue.

    Update: I did a troubleshoot after following the steps from that thread and it says "Problem found: Windows can't communicate with the device or resources (primary DNS server)"

    Thank you greatly

    Default DNS Server isn't responding

    When I arrived back at uni this afternoon I discovered my PC would not connect to the Internet and this is the problem that comes up. I've checked over the Internet and none of the "fixes" have worked so far. Any help appreciated.
