I cannot play this game on Xbox Live, though I am able to play EVERY other title I know of on my internet connection.
Netgear wireless gateway router
I am plugged directly from the router to my 360.
I've tried three ethernet cables, two of which were brand new.
I've cleared the cache
Removed the HDD, booted, powered off, rebooted with the HDD.
The game has yet to manage to get me through an entire MP game on this connection- At some point during the match it'll freeze up, I will get a "disconnected from Xbox Live" msg, and I get kicked back to the menu screen. It varies. Sometimes I get five minutes to play, sometimes I get 30 seconds.
As an added bonus, I can now force my 360 to break connection from Xbox Live by pressing the "Rainbow Six Vegas: IMMEDIATE DISCONNECT BUTTON" in the multiplayer menu.
Did I say "IMMEDIATE DISCONNECT"? Sorry. I meant to say The "Refresh Server" option, which will ALWAYS result in a disconnect.
For what it's worth, for those two minutes in which I'm able to play, the game is pretty fun.
I have the same problem, I have a direct connection to my modem (it is wired). After reading many of these threads pertaining to this problem and seeing how people are having this problem regardless of whether they have a router,wired or wireless connections and with various ISPs being affected, it seems that the problem lies with UBISOFT not with people's internet setup. The cause could either be faulty discs, or poor online game design. I'd hate to rant but I'm on my last nerve with this. I wish that UBI would atleast come out with a responce. I would be happy with anything, even if they said that they could not fix this problem. Atleast the I would know that there is nothing that could be done and I could go back to the store and get my money back.
