    Network disconnect


    After a period of several hours my computer disconnects from the internet. It still shows a good connection in network sharing center. I have to reboot to reestablish connection. Any ideas for the cause to this problem? I have a 3 year old Dell Inspiron 1720.

    Hi mikeee52,

    I'd guess that your DNS or default gateway is dropping out.

    You can check this quite easily by opening an elevated command prompt and running the following command
    IPCONFIG /ALL.

    Look next to DNS and Default gateway and let us know if anything is blank or starts with 127.x.x.x or 169.x.x.x

    EDIT: I should have added, to open an elevated command prompt, type CMD into search, then right click on it (once found) and select Run as administrator.

    mikeee52 - You need to do the test only when the issue occurs... but I guess you know that right? In the meantime i'll write you a little batch file to refresh your settings. This will save you rebooting while we work out the root cause. More to follow....

    EDIT: I've attached a little batch file for you that resets your connection should it drop out. This is a band-aide only (to save you rebooting) and presuming that the issue is related to a drop out in your ipaddress, dns or default gateway. Unzip the file and run it as an administrator (right click).

    Once you confirm the ipconfig /all test we'll move forward with finding the cause and a solution.

    This can also be caused by channel cross over from other routers in your area. Changing the channel in routers control panel will usually fix that sort of problem.

    Test out using different channels for a day or two and let us know if it helps with the dropped connection problem. Windows 7 seems to be sensitive to this sort of thing.

    What about if his router's DHCP Client Lease Time is very very short

    It could also be due to other devices on your network having a static IP address and this being the same as yours. So it drops yours when they get turned on. A good culprit for this is a printer.

    But let us know the ipconfig /all results when it occurs and it will much easier to troubleshoot. We'll stay tuned.... I realise that this can take a while

    EDIT: hmmm there should be a pop up warning for this scenario though.

    Before we go and do wild guesses, why not ask the OP what's his ipconfig /all output + ping test when it happened, it'll cut the wild goose chase time...
