I am having an issue with xbox live disconnecting from parties on occasion. When Im disconnected, i have to wait 15 seconds or so, then I reconnect most of the time. other times it says cant join xbox live party. also I occasionally have friends that i cant connect with in an xbox live party at all. When I do connect, It takes 20 seconds for the party to finally connect. I have DSL. I have 10 MBPS download, 1 MBPS upload, and ping at 30ms. I opened port 88 UDP, and port 3074 UDP and TCP. My NAT is open as well. I have a linksys wireless - G router with a wired connection to my xbox. also a wired connection from that router to my desktop. please let me know what i need to do to troubleshoot this please.
