GW2 connectivity issues somehow destroy my internet connection

[Endorphinz.5328]

I don't know how this is even possible, but after dealing with it for months I have to come to the conclusion that somehow, whenever Guild Wars 2 decides to kick me off the servers, there's about a 50% chance that my computer's internet connection just completely dies. It comes back after a couple minutes, luckily enough.This never happens with any other online game or service I use. Can someone please tell me what would possibly cause my internet to just stop working whenever GW2 decides to have a bad connection?? I'm on my last straw with this game.

I'm getting disconnected several times a day while my internet is totally fine. I'm at a solid 160 Mbps and never get disconnected from any other games only GW2. What's going on here.
