Last Friday (11 Jan 2013), my Xbox 360S suddenly couldn't connect fully to XBL. When I say "fully", I mean that it would get as far as letting my profile sign in and showing me (accurately) what friends were online, but would show the "Connect your Xbox 360 to the Internet to explore games, entertainment, and more" message on the homescreen. Attempting to play any online game would further prove that I wasn't actually connected.
I ran the connection test and it showed that the console was successfully connecting to my home wireless network and the Internet but then failing at the XBL step. I was unable to log in fully to my XBL profile. Some other times, all three legs of the test would show a successful connection but I still wouldn't be able to connect to XBL afterward. The error code that I typically receive when XBL won't connect is either 80072ee2, 8007274d or else
I contacted phone support for XBL and they worked with me for hours with the usual steps - recycling modem/router, MTU, NAT, port forwarding, delete and re-download profile, rollback and re-apply recent updates, etc. - even went so far as to set the router back to factory settings, but nothing worked. I separately also worked with my ISP (Time Warner) and the router manufacturer (Netgear) and as expected, they had no answers and simply pointed the finger at the other two.
It's important to note that no other connected devices are having any issues on our home network, including this laptop, several iPhones and Kindles, etc. Also, aside from adding two new phones to the wireless environment, there haven't been any changes to our network since these problems began.
I recently tried setting up my old Xbox 360 with the separate wireless adapter and it worked (although sluggishly) in the same room as the router. Unless someone has a magic configuration bullet here, I guess my next step would be to bring the old 360 down to the TV room and confirm that it can connect successfully there as well. If that's the case, then wouldn't it point to the Xbox 360S as having suffered some sort of hardware failure?
Thanks very much. My detailed info is below.
What Country/State/Province do you live in? Ohio, USA
Modem brand & model number: Motorola Surfboard SB6141
Router brand & model number: Netgear WNDR3400v2 (up-to-date firmware)
If Wireless, are you using a white or black external adapter, or an internal (Xbox 360S) adapter? Internal 360S
Things you have tried:
Is UPnP Enabled? Yes/no/Unknown Yes
Do you have a NAT error? If so, what is your NAT? NAT is open (this tended to somewhat fix the error vs. having it set to "secure"; however, performance was horribly slow, i.e. menu tile would be blank for minutes and the overall connectivity problems resurfaced from time to time)
Any Error Codes you encounter: 80072ee2, 8007274d and
Who is your ISP(Internet Service Provider)? Time Warner Cable
