Internet Disconnect that even turns off the connection in my PC

Whenever I play PoE for a few minutes (10 at most), my internet connection gets disrupted and I'm kicked out of the game. But this disruption disconnects my internet from my PC too. I can't use the internet for a good 5 minutes after this disconnect.
This issue only happens when I play poe and not when i do anything else. I've been trying to troubleshoot it for the past 4 hours and everything ends in the same result. I'm pretty sure it's a bug. Please fix it
