Hey there!
I've seen people with that same issue online and it happened to me too.
I've tried the following and nothing worked:
- Resetting the network (losing all passwords :( )
- Resetting the router itself and re-configuring it from scratch (this worked for literally 5 seconds)
- Putting in a lot of netsh commands in an Administrator CMD
- Modified some registry values which turn on "Probing"
All of these to no avail.
What worked was the following:
Paste this into a .txt file and then change its extension to .reg:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\NlaSvc\Parameters\Internet]
"ActiveDnsProbeContent"="88.221.52.97"
"ActiveDnsProbeHost"="www.msftncsi.com"
"ActiveWebProbeContent"="Microsoft NCSI"
"ActiveWebProbeHost"="www.msftncsi.com"
"ActiveWebProbePath"="ncsi.txt"
"EnableActiveProbing"=dword:00000001
Now double click that file and grant it Administrator rights.
Windows 10 should now stop nagging about no internet access after around 5 minutes. I didn't get to try rebooting straight after this, but this worked out for me! :D
NOTE: The path in the registry file might be the following instead:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NlaSvc\Parameters\Internet]
