Help fix my xbox live

[arjue]

I have some very strange problems with xbl. I can download anything off the marketplace with no trouble, yet if I search for a multiplayer game in anything, 99% of the time it can't find any and after 30 seconds it disconnects me. However, if I'm invited to a game, I can usually join. If I do a connection test, it passes with flying colors.

I have given my 360 a static IP and have forwarded a bunch of ports on my router and modem. I am using a wireless bridge (lol spodaddy). I used the same setup for my orignal xbox and I had no troubles with live at all.

Any ideas what could be doing this? My PC runs off the same type of D-link node without any troubles.

ps, microsofts fantastic support:
