As of last Wednesday, I haven't been able to join any multiplayer games. (I've tried getting into Black Ops, Modern Warfare 1 and 2, Assassin's Creed: Brotherhood, and Red Dead Redmemption). I still have a strong wireless network signal, and my console still gets a good connection to X Box Live, but I just can't join any multiplayer games. For example, when I try to join a Core Team Deathmatch game on Black Ops, it searches for a game (it actually says something like "0/50 good games", and it scrolls from 0% to about 98%, then once it hits 98%, the number in front of the /50 starts to increase), then, instead of saying "trying to join XX potential matches", it says "waiting for the host", then it starts the "search" all over. It does this several times, then gives me an error message that says, "Could not connect to the server. Please try again later." or something like that. It's very frustrating!!! It's been going on for over a week now. It was working just fine one day, then the next day, I just couldn't get into a game. I've tried resetting my modem and router countless times, updated the router's firmware, changed the router's wireless channel, put the X Box in the DMZ, deleted the wireless network from the X Box then reconnected it, and I've tried all the "port forwarding" suggestions, all with no success. I even tried connecting the X Box directly to the modem with an ethernet cable, and that didn't work either. I'm all out of options. Can someone please help me??? I just want to go back to being able to play online like I could up until last Wed. Thanks!!!
