    Default Windows 7 DNS server not responding

    This is a recent problem where I am unable to access the internet. I confirmed that the computer can access the internet if connected directly to the ATT modem.

    I have a ddwrt repeater bridge that is connected to my desktop. I can access this router but there is no connection to the internet. I have tried to flushdns, ipconfig/release and ipconfig/renew, tried setting the DNS server address to 8.8.8.8 and 208.67.222.222 with no luck.

    I did uninstall Mcafee but still no internet.

    I tested the desktop with another ddwrt repeater bridge to make sure it was not the router that was causing the issue. On the second ddwrt router I connected the Vista laptop and was able to access the internet. I connected the desktop and am getting the same results as the first ddwrt router.

    I tried the following:
    Reset WINSOCK entries to installation defaults: netsh winsock reset catalog and press enter
    >>You must restart the computer in order to complete the reset.

    Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log and press enter
    >>Reseting Interface, OK!
    >>Restart the computer to complete this action.

    Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log and press enter
    >>There's no user specified settings to be reset.

    I can ping the ddwrt router but I get a time out when trying to ping the ATT modem.


    Here is the results of the ipconfig/all

    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?
