Additional authentication needed???

I've been trying to fix this for a couple of days but nothing on google helps so it says additional authentication needed and gives me 2 options

1) the first is to authenticate now which just takes me to a page where it says there's no wifi even though there is as I'm on my phone

2) second says add alternate MAC address which when U press that it just takes me to my advance network setting I enter a MAC address manually the console restarts but it says the same message again

Anyone please help if u know or Xbox staff please I can't play on my Xbox

:)

 

Additional authentication

Are you connecting in a student dorm WiFi, or an apartment complex that provides WiFi to the inhabitants? It might be, that when you first connected your other devices to the network, you were presented with a welcome page,
where you had to authenticate your devices by agreeing to the WiFi's terms of use, or provide a code or password you got from your landlord or whoever runs the WiFi.

Since that has to be only once, you might have forgotten about it.

If you try to connect the Xbox One to that network, it might require you to visit the portal page again, and authenticate the Xbox access with the WiFi.

 

Additional authentication

How do you fix the problem

 

Are you connecting your console to a hotspot, or a guest network at a hotel, which are secured by a captive portal (authentication web page)?

The second option require you to spoof the MAC address of an already associated/authenticated/authorized device and not the MAC address of whatever interface you're using to connect your Xbox (ethernet/wireless).

Also, make sure you're not concurrently connected with the current associated/authenticated/authorized device and your console, as they use the very same layer 2 identity.
