Playing from Italy. Required UDP ports are open. Nat is open. Playing on a 30 Megabit optic fiber connection. Hardware requirements are respected by my pc. I can't join a co-op play with any friend: after receiving an invitation i join the world but I'm just all alone. No enemies nor other players. I can just walk for a while before getting an error: I've received both Gabbage and Lattuce, and sometimes a random loss of connection. The frequency of those errors is kinda randomic: I've been able to play for more than an hour without problems, starting to think that everything would have been ok that suddenly everything brokes out. I've had to restart Battle.net at least twice before being able to play again. I've read all the guidelines already published by Bungie and I guess I've no more ideas of what to do. Any Idea would be appreciated. Many thanks to everybody.
