Mass Effect 3.7: "That was for Thane"

[Edge]

What did you do to solve your router issues?

I've been having terrible lag issues the past week and also there have been times when I cannot connect to a party or join a game when I'm invited. I opened the respective ports for ME3 last night, but that didn't seem to help.

We took the offending router out of the network and everything worked fine again. Might not be an option for you, obviously.
