    Ever since I hooked up my D-Link DIR-655 I've had weird DNS failures. It seems to happen when there hasn't been activity on the network for awhile on whatever device I power on(PS3, Xbox 360, wired PC). I'll be able to play/browse the web for 5-10 minutes then suddenly I get DNS failures on the browser and Unable to Connect(Can't Resolve DNS) on the consoles. It lasts for 5-10 minutes then suddenly I'm fine with no more issues until the next time there's been no activity. If I flush the DNS, it's a 50/50 chance of resolving the issue quicker.

    I have upgraded the firmware on the D-Link and am running Win7 on the wired PC.

    i have seen a few thread on other sites saying the same thing.

    What revision of the D-Link DIR-655 do you have?.

    based on peonowns post it may be a bug in the firmware

    BUT

    i would run the following tests and see if a DNS issue

    you can always add some open dns server IPs to the router - if the ISP DNS are an issue - I see this type of error frequently
    would you post the following tests when the internet is working OK, and then repeat ALL the tests when the internet disconnects.
    Make sure you also indicate on the reply which tests are for what condition.

    ------------------------------------------------------------------------
    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 the results in a reply here.
    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.

    We would like to see the results from an ipconfig /all - post back the results in a reply here.

    This should also work for windows 8
    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 into notepad and then automatically open the notepad and display on your screen.

    Now all you need to do is copy and paste those results into a reply here
    to do that:
    From the notepad menu - choose Edit - Select all
    all the text will now be highlighted
    Next
    From the notepad menu - choose Edit - Copy

    Now go back to the forum - goto the reply and then right click in the reply box and paste the results.
    The results from the notepad should now appear in the forum reply.
