I ask here because I have and odd issue and, having tried standard solutions, now it's time to ask for help.
I can't find firefihgt games. Whatever other games I play with my Xbox 360 works flawessly. Halo Reach Competitive game modes also works well.
But when I try to play Cooperative games, I find no games at all, nor players to play them.
I've tried all router resetting and configuring workarounds, with no luck. Also, all Xbox 360 network tests, again with no luck.
I tried to change the router itself to another brand... with no luck. I have to say that every other service that I want to use, works. I can use skype, messenger and others with webcam and mic. I can download and upload by using ftp, torrent, emule, jdownloader... Even I have a kinect and have tested the kinect videochat service, working all flawesly.
It's only the cooperative games in halo reach, that I can't play at home. But...
I took my console to a friend's house, and it works there!!!!
The only difference is that I use DSL and he uses Cable. The rest is the same.
And even this one: If we (my friend and me) set up a Live Party and HE is the group 'boss', we'll find games and I'll play. If I am the group 'boss', we won't find games...
WHAT CAN IT BE?????
