v79 has problems
It was said v78 had security problems, so v79 came out. v79 occasionally nixes out my connection to the router. v77 never had that problem.
I'm rolling back to v77 until v80 comes out that addresses this problem. The TAP stays connected, but nixes the network connection to my network.

Have you tried fully uninstalling the app and reinstalling it in case it's just and upgrade blip?
EDIT: Just noticed the exe process (apparently also part of the PIA client) now consumes ~375MB of resident RAM. That's almost a GB of resident RAM for what amounts to an openvpn front end!
It's the TAP driver doing it, I've done a reinstall of program, did a reinstall of TAP driver, nothing fixes it. As soon as the TAP has Internet access, it nixes out showing the wireless card has no Internet access, but it does have access.
The reason it does that is that so when the VPN disconnects, you're left without Internet access therefore killing the internet access until the VPN comes back up. It does that by removing the default route, and without it Windows realizes that adapter has no default route therefore no Internet access and marks it as such. This is fine because it's the TAP that provides the Internet access when the VPN is connected.
But, if I do disconnect, it does go back to normal and shows it has Internet access.
