Xbox live connectivity

[kicker226]

I can connect to xbox live perfectly, altho it takes sometime to connect.  when i connect and enter a game to play online it tells me im disconnected.  ive spend 7 hours on the phone with xbox live support.  the error status codes that i'm getting is that i do not have a constant stream of broadband running to my xbox.  i bought a brand new router wireless combo from best buy, switched my ethernet cords and everything.  anyone have any advice, or know how to get someone out to my house to test everything and make sure it's okay?

thanks
