Wow kills my internet

I just reinstalled the game a couple days ago and this has been consistent. I never had this when I played before though.

Wow seems to disable the internet on my main gaming PC. It is hardwired to the router. Other devices on the network are unaffected. Wow itself is not impacted. But if I alt-tab out to use any other internet based software, it acts as if I’m not connected. It does not occur immediately and I haven’t noticed a consistent amount of time before it happens. This continues even after I log out of wow. The only way to regain internet access is to restart the PC.

I don’t even know where to begin troubleshooting on this one
