AT&T: my xbox 360 cant connect to internet

I cant connect to xbox live with my 360 and my internet online.

Ben thanks for the reply.

So I have the xbox 360. i just got my new internet service with t mobile home internet. In case you aren't familiar with that. it is basically home internet over the 5g network. and broadcast 2.4 and 5g.

All my other devices connect great. but the 360 has problems..

The 360 will connect to the t mobile router but not from the router to the internet. I do not get an error, but on the Test Connection it shows xbox live failed, internet blocked.

I called the tech at t mobile, he said the xbox 360 needed a code or something because it has problems with with IP address porting or something and the code or IP address Xbox could give me would allow me to connect.

I set up a 2.4 connection just for the xbox and the WEP2..

So I don't know how else to get the 360 on line.

Same prob. I cant access to my personal information (account) from my console, can t access to Xbox Live an so on. But my Xbox one is connected to the internet (and I check my Xboxlive membership with my computer).... Prob with the Update ?

my xbox one won't connect to the Internet

No, this won´t work.

The Xbox One doesn´t support external HDD´s yet. You have to join Xbox Live with your gamertag, after that you can download your gamertag on the Xbox One. Can´t you connect your Xbox 360 with a wire to your router? If not you can use a Xbox 360 of a friend
with an internet connection.
