Maybe someone can help me. I just got my xbox live beta kit today and can't get online. When I run network settings get green across the board and it says that I'm connected. But when I go create my account, I select Unitedstates for my billing and I get the message "Xbox live is not responding. Please try again later." I called tech support, the guy took down my error codes and said I would be contacted by email. I'm using a Sprint 645 series cable modem and a linksys BEFSR11. When I connected my xbox to my network a few weeks ago in anticipation for playing xbox live (my xbox works with gamespy tunnel btw) the tech for sprint mentioned that this DSL modem was pretty much a built in router. I don't know if thats the reason why I can't connect using direct connect as well. http://betaforums.xbox.com/ShowPost.aspx?PostID=61966 If you scroll down to the 4th post in that link, you'll see he has pretty much the same equipment I do (I'm pretty sure my Sprint 645 series is just a rebadged Zyxel Prestige 600 series modem. Setting my MTU to 1492 as he later sugest didnt help either. I've tried the other things you would imagine ofc, opening my ports, setting the xbox as DMZ. Anyone hear of this problem with this equipment / isp? Any suggestions?
