    IPv6 Connectivity: No network access


    Just got a new PC, and installed Windows 10 Education got a copy from my school, UBC, plugged in ethernet, and everything was fine for a little bit but then the internet stopped working for certain sites. Google sites work fine, many other sites load after a little bit of time, but lots of sites and apps won't load at all, or enough to be usable Netflix, Steam, Spotify, etc.


    After some searching I think I've narrowed this down to a problem with my network drivers. Specifically, under either Ethernet or WiFi it says IPv4 Connectivity: Internet, and IPv6 Connectivity: No network access. I've tried everything I can find, and nothing has fixed it. Troubleshooting doesn't pick up anything, none of these: netsh winsock reset, netsh int ip reset, ipconfig /release, ipconfig /renew, ipconfig /flushdns have done anything, I've tried a few times. I've tried even disabling IPv6 Connectivity, but that doesn't work either. I've tried changing DNS, no luck. Updating drivers, IP helper service, endless restarts--I can't even count all the things I've tried, but it's everything a few pages of google results has.


    Any help would be much appreciated, this is really frustrating and has been happening for three days now.


    Thank you so much!

    :)

    IPv6 No Network Access - Windows 10 1703

    Hi KumaTee,

    It could be that there is an application in your system that blocks IPv6 from having network access, or that your network settings are incorrectly configured, etc. For us to isolate the issue in IPv6 having a no network access, kindly respond to the questions
    below:

    • Have you made any significant changes to your device prior to the issue?
    • Are there any third-party antivirus applications installed on your device?
    • Have you tried restarting your modem and wireless router? This would help create a new connection to your Internet Service Provider (ISP). Keep in mind that all devices that are connected to the network would be temporarily disconnected.
    • May we have a complete list of the troubleshooting steps that you have done? This is for us to know and to avoid any duplication of efforts on your end.

    We look forward to your response.

    IPv6 Connectivity: No network access


    That is one of my issues with Win10, its connecting to same internet as this Win7 but Win10 is connecting via IPv6 ( Internet Protocol version 6) but has no internet access. hover pointer over wifi icon and it says verifying network, no internet access.. Win7 laptop has Qualcomm wifi, Win10 has Realtek. Only way for Win 10 to connect on IPv4 is set it right near modem. even then windows does not connect to internet.
    I even went in BIOs and set network to IPv4 EUFI or what ever. where IPv4 would be the only connection and it still connects to IPv6.
