Additional Authentication Info Needed

“To connect to this network, you’ll need to enter additional authentication info. If you have an alternate MAC address, choose Enter alternate MAC address.” 

I’m trying to play on my xbox one but everytime i’ll set up an internet connection and try to go onto a game, that message will pop up. I have already entered an alternate MAC address but it hasn’t worked. I’ve tried restarting both my xbox and my router but that hasn’t worked either. All the TV’s and Phones are working fine with the internet but the xbox isn’t. It also says UPnP is not successful I NEED HELP.

UPnP will not be successful with only the AT&T Gateway as it (intentionally) does not support UPnP.

The message you're getting is particular to the XBOX, and I'd suggest reaching out to the XBOX community or XBOX support for assistance.  If they tell you to that you need specific changes to the Gateway settings and you don't know how to make them, come back and let us know.
