DeltaNovember

Okay, got the game friday. Every time I try to join a multiplayer server, it says connection failed after a bit, and then my internet doesn't work. It's done this all weekend, without fail, every time. I can play any other online game with no issues, but this game literally shuts my internet down. Anyone out there to give me a clue on this?

Plugging my modem directly into my computer, bypassing router, worked. Why in the hell that is, I have no clue.

ARMA 2 has full access through firewall: even tried it with firewall completely off.
