Even though it was working earlier this morning, I can’t open a lobby in any part of the game unless it’s Campaign or Theater. Every time I try going into Forge, Arena, Wargames, Custom games, absolutely nothing happens except for the click when attempting to select it, won’t even try loading up a lobby. But every once in awhile on the Menu, a message pops up “Connection Lost. You have been disconnected from the local network. Returning you to the Main Menu.” What has me furious is that fact I’m NOT disconnected from Xbox Live, everything else works fine, and my router isn’t having any problems.
Are the servers having problems or is anyone else getting the same issue? This has been going on for hours for me and urgently need help. I’ve attempted to reset my connection to my modem and still has no effect.
Welcome to the club. Has been doing that to me since 4pm today. Can’t believe they haven’t fixed it yet.

Have you tried Forge?
I just got a ban hammer for not being able to stay connected to the servers. Why do I get punished for something that is not working for everyone? I’m seriously about done with halo. You all are never ready for when things come up. You all should have been ready for the amount of people to be on after the holidays. You have yet to put out a game that isn’t working properly
My wireless internet works beautifully yet my profile doesn’t sync, my reqs and armor don’t pop up, and when I manage to join a multiplayer game it normally kicks me out halfway through the game.
Sadly, I think I agree with Carl. I’m coming really close to being done with H5.
I’m seeing lots of forums on this issue and 343 had better do something about it quick or their going to lose lots of players.
