Cant connect xbox one to internet (but router works)

This is a known Problem

forums.xbox.com/.../443344.aspx

you NEED to update your router to the latest Firmware ! Problem should be solved.

no reply from my uncle right now but if this is only a phone problem is it possible to fix it? or is my uncle sitting on a brick?

You said turning off the router disconnected the wireless phones?

You don't have wireless internet phones connected between your modem and router do you?

If so I read in another thread that they have their own IP addresses and can cause a double NAT making it impossible to get the xbox connected.

If you meant you just disconnected the power to your standard wireless phones by mistake then disregard what I said.

Thank you for the fix! The firmware update was the problem. It works perfectly.

Thank you for your reply, I'm updating my uncle right now. We will see if that works if I get over there.
