problem getting connected

I check my multiplayer connection and I always get "It's all good, there should be no problems with your multiplayer connection". But clearly there is a problem that it cannot detect. ;_;

I'm pretty sure it's not a problem with my account or connection, is anybody else getting the same problem?

i normally connect to xbox live but something , there aren't problem in my connection but i don't know why i get disconnected a few of times for then be okay.

what is the problem?

This is also happening to me too, which makes me feel like it's not a connection problem, but more of a XBOX LIVE problem instead. I get lagged out of any game I play online within 10 minutes of starting. I know it's not a connection problem because about
two days ago I was playing perfectly fine and getting a four bar connection.

I cleared out my cache like you suggested but my 360 isn't connecting to the internet like it should. I'm on a wireless connection and I usually have no problem with it. I noticed the problem of connecting on Tuesday but I didn't think anything of it and
now I still can't get connected. I've tried restarting the router but it's still not connecting. The system gets through to the Network but it fails when it tries to connect to the internet.
