Ethernet Connection Issues

Hello all, I'm an avid player in desperate need of some help here!

I recently moved into a new location where the internet is less than great and I've been having trouble connecting to the game.

Wifi: I can connect to lobbies easily, but during matches I consistently drop connection. This area is notorious for being spotty, my router is up to date, and I have the best package/service. This really cannot be improved upon, the wifi is just generally buggy and drops out here.

Ethernet: This holds stable and fast. I am able to play any game I want with great performance except AOMEE. Connecting to lobbies takes 60+ seconds and normally times out. In the rare times I am able to get in, it's only ever if it's just me and another person. I seem to make it more difficult for other players to join too and they often complain that I lag in lobby, even though if we ever make it into game there is zero latency issues (no lag on either side).

I haven't been able to connect to a damn game in weeks, and the entire thing is just too weird! It seems to be specifically related to the lobby system somehow.

Any help at all is super welcome and I'll run with any suggestions I can. I've done the basic tech stuff like firewall exclusions, restart the router, etc :)
