    Network connection constantly disconnects. Restart only to get it back


    So I have continually had an issue with the network connection dropping. Only way to get it back is to restart. Starting with the first preview build I installed this was an issue. I have tried disabling IPV6. I have disabled power management in the NIC and the problem just continues. If i try to disable the network connection after this has happened the computer locks up. If I uninstall the network card once this has happened it locks up as well. I can do both fine before this happens. I have performed the following commands ipconfig /flushdns, ipconfig /registerdns, ipconfig /release, ipconfig /renew, NETSH winsock reset catalog, NETSH int ipv4 reset reset.log, and NETSH int ipv6 reset reset.log. Nothing out of the ordinary in the event viewer with the exception of "Name resolution for the name fg.ds.download.windowsupdate.com timed out after none of the configured DNS servers responded". In order to use the system I have to disable any applications that use the network such as dropbox or onedrive or downloading of files in the browser. Im tired of being told its your network card. Its not. If I boot into windows 7 on the same PC I can use the connection without issues. I have now tried a second network card and it does the same thing. Please someone help. The computer is unusable at this point and I am contemplating just going back to my Windows 7 permanently and don't really want to do that. Also as a side note it seems the longer I let the machine sit after initial login the longer I can go before the issues pops up.

    Provide detailed system specs.

    Easiest way: Press [Windows Key] + [R] and type "msinfo32" and open it.

    Or do a start menu search for "msinfo32" and open it.


    Go to File > Export

    Save file to desktop and either copy+paste its contents here, or upload the file to here or pastebin or wherever.

    Looking over the details now. I'll let you know if I spot anything related to your network issues.

    Edit: This may actually be part of Windows 10, I retract this post.


    Looking further.

    I am having the same issue. I have tried many of the same steps and it still disconnects every few hours. It was worse before I disabled the power management on the network adapter. I also tried disabling McAfee's firewall. And removing all the wired devices from my router thinking perhaps the router was overloaded. My wireless connections are all fine. Other devices wired to the router are fine. Just this PC keeps losing it's connection. I the drivers are up to date per the Windows 10 'Update Driver' check. To get the connection back, I have to reboot the PC and reset then LAN - neither alone work.

    I have a Broadcom NetLink Gigabit Ethernet adapter. cnmsales, what adapter do you have? Another thread on here had the same adapter as I did. The only other correlation I found was that it is worse when the Philips Hue hub is connected to the router. It seems to me there is a router conflict and this connection gets shut down somehow. Then it does not auto reset. But I don't know much about network cards and routers so that's a very weak theory at the moment.

    Determine the chipset of your broadcom card. See this link on how to do it

    Ethernet NIC Driver Support | Broadcom

    Then go to this link

    Downloads | Broadcom

    and download the drivers for your chipset. Then update your drivers manually with the downloaded drivers.

    No Broadcom Advanced Control Suite. And b57udiag doesn't isn't found when running that via the cmd prompt. My Device Id is also not in the device list. The ethernet adapter is integrated into the motherboard. That said, my motherboard from 2009 though it still does quite well. I did find the device id here: http://www.pcidatabase.com/vendor_details.php?id=767. I will have to open up the machine and look at the chip to see if I can determine the number.

    Just to double-check, can you confirm you have gone into Device Manager, looked at Power Management within Properties, and unticked the option 'Allow the computer to turn off this device to save power'?
