I have to agree that this is i no way related to a modem or a router. I can play every day then all of a sudden I can't log into a server. I look time and time again for a fix, make sure battleye is updated, reindtall ARMA 3, router/modem reset., Nothing I find anywhere fixes the problem. Then within a week I'll retry and mi back in. No updates or changes to the game of to my PC. I can play every other game out there but the one I want to play. The error doesn't say "Router Error", it's Battleye! Three times in the last few months this happens then goes away . . .
