Anybody know how to fix the chat invite problem?

[al capOWNage]

Once in a while when i accept chat invites....It will say 'Joining Chat' But i never am able to get through....What's up what that?

Can't help but I get it alot, with one friend in particular. He had to reset some things on his router and now we can finally chat.

It's almost always a router issue. this is the same issue as if you can't join/host a game with a friend, or have problems connecting to games sometimes. If you go direct to your modem, it always solves the problem for me, however, that's not really an option for most of us since we need to share the connection or aren't near the modem box SO if anyone knows any good tricks to make a D LINK wireless router (forget the model number buts its that one with a/b/g wireless) work better let me know! =)
