2Wire: Problem with my Xbox 360

I think I may have confused you with my suggestion, by connecting the failing Xbox directly to the router. In this equation, I'm not referring to your Linksys E1200, but instead the 2wire gateway.

You mentioned that you already have one of your Xbox 360's connected directly to the router/modem (2wire). I would like you to try with the exact same setup as your working Xbox 360, but with the failing 360 machine connected directly to your 2wire gateway,
without the Linksys E1200 in transit, or any other networking device for that matter. With the exception for the failing Xbox 360 and your 2wire gateway.

Topology:

2wire (gateway) ------ Ethernet -------
Xbox 360 (the failing console).

Before you go ahead, go to Xbox System Settings and select
Network settings. Select connection type and Configure Network. On the
Additional settings tab select Restore network settings to factory settings.

Turn off your Xbox.

Turn off your 2wire gateway and let it sit for a couple of minutes.

Turn on the 2wire and wait one minute for it to connect properly and wire your failing Xbox 360 the exact same way as your working Xbox 360.

Now on your console, head back to Network Settings and select
Test Xbox Live Connection.

Post back and let us know how that goes and we'll go from there.

Thanks!

Sorry for the late reply!

[quote user="Cartoonite"]I finally got a working network cable running up through the walls into the room and connected the 360 directly to the 2wire modem.[/quote]Did you actually have your Xbox 360 directly connected to the 2wire gateway, or did you have
any networking device connected in between this path?

It would be great if you are able to find out the model number of your 2wire gateway.

Could you try, once more, to directly connect your Xbox 360 with an Eternet Cable to the 2wire gateway, but this time, make sure you disconnect your second Xbox 360, along with the Xbox One, from your network.

Disable UPnP and reboot your 2wire gateway.

Enable UPnP and reboot your 2wire gateway.

This procedure will refresh the map table.

If it's possible, are you able to try and connect your console on a different network (friends house), to verify if this is exclusively tied to your network, or not.

Keep us posted!

taidara, the 2wire is the i38HG. The WAN IP provided to my Netgear is the public Uverse IP, 99.138.xx.xxx. I'm really starting to believe the 2wire is the issue here and/or AT&T is blocking something for Xbox to function correctly. I tried Netflix on my
360 last night, one bar for three hours. Fired up Netflix on my Samsung TV (the one the 360 is connected to) and it ran at full 1080HD.

CFG, the netgear is upnp enabled. Thanks though.

[quote user="Irixion"]If I may ask, why do you have an E1200 if the Bell device is a modem/router combo? Do you have the 2wire Modem/Router set to just modem?[/quote]

The 2wire device is operating as a modem/router. The E1200 is (was) operating as a wireless bridge. That is, the E1200 provided a wireless link to the 2wire device for several devices that only support wired connections. It was the only way to get wired devices
upstairs connected to the 2wire without running cables through the house or walls.

The connectivity path at that time was:

360 -> RJ45 cable -> E1200 -> wireless link -> 2wire -> RJ11 cable -> Internet

Now that I have a cable running up from downstairs to a switch in the next room, the E1200 is operating as a switch. The 360 is connected to one of the LAN ports and there is a cable running from a different LAN port to the switch in the next room.

The desired connectivity path is 360 -> E1200 -> 2wire using all wired links but the cable that was supposed to make that possible isn't working so for now the extra hop is required.

I am reasonably certain that the 2wire device is configured properly since all devices on the network are able to access the internet as expected. Even when the problem 360 is disconnected from Live, connectivity to the internet is maintained. Also, this
networking setup worked flawlessly for a year or so and there were no changes when my issues first started.

I have tried several different methods that I found online and finally found one that works. I have att 2wire an xbox one and 360 and now both run with an open nat at the same time and have not disconnected or given me nay problems at all for 3 days now.
