Internet intermittently disappears but LAN still accessible

I have a Windows 10 desktop connected via ethernet cable to an access point. I have a problem where *sometimes* internet will not be available on this particular PC. When this happens, other PCs connected to the same access point can still access internet. The PC that is affected can still access LAN (e.g. samba resources on other PCs, open router login page, ping gateway), but no access to internet like pinging DNS servers. The problem is intermittent and internet access will be restored without any action *after some time*. A couple of times I tried to switch my local network IP address and that fixed the issue instantly, other times it didn't help. Same story when I tried to turn firewall on/off.

I have tried to reset network stack, uninstall drivers, install all windows updates and still no permanent fix. The issue is most likely to occur on startup, but it it has also happened while I was working on the PC.

Looking for tips on how to debug this issue. I'm assuming the cause is on the Windows PC not the router since other PCs are not affected.
