XBOX LIVE CONNECTS AND DISCONNECTS QUICKLY!!! HELP

OK im sure there are tons of these threads on this forum but I have done everything most of them say and nothing works for me! I can pass the Xbox live test conection and I connect to xbox live but then it disconnects quickly... There is no problem if I connect the xbox directly to the modem.  I have no idea whats going on. I have tried lots of different types of settings, even DMZ.  I dont know what else to do.

Ok, does this happen in-game, or while you're still in the dashboard? Can you please run a speedtest on your PC, and then post the results here, too? Thanks!

Did this solve your problem?

Sorry this didn't help.
