Issues with constant disconnects, but only in Helldivers.

As of maybe 2-3 weeks ago I can't make it through a single round without getting dropped and having to rejoin. Never had an issue before and no other games gives me so much as a connection hiccup. Are HD2 servers just absolute dogshit or could there be something else I'm just not seeing?

I had 500Mbps on a hardline and just recently upped it to 1000Mbps.
