Additional Authentication Needed

Jessicaah1lol · May 31, 2019

Okay so, my brother and myself were playing fortnite and then both of us at the same time got kicked out the game. We thought our wifi was just acting up and we reset the xbox and router multiple times with no luck. When i clicked “test network connect”
this message popped up “additional authentication needed. To connect to this network, youll need to enter additional authentication info. If you have an alternate MAC address, choose Enter alternate MAC address”.

I dont know what to do to fix this problem its been going on for about 2 days now.

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.

Hi Kevin,

Every hardware device that connects to a network has an identifier code that is called a MAC address. This is how devices recognize each other because every device has a set and unique MAC address, unlike an IP address that cycles and changes periodically.

If I'm not mistaken the additional authentication required is your internet provider asking for your Xbox's MAC address to add it to the approved list of devices that your router allows to connect to. When you select the authenticate now button, it will
not load the page since it's trying to load a secure site that your ISP would authenticate the MAC address by first signing in to your router settings.

We have seen higher instances of this happening with AT&T for some reason, but essentially you need to make sure with AT&T that your Xbox is not being MAC filtered out from your router.

Before contacting AT&T, I suggest troubleshooting the console's MAC address and see if makes the Xbox more discoverable. Go to Settings>Network>Network Settings>Advanced Settings>Alternate MAC address>Clear and then select Restart Now when prompted.

If that doesn't work, call AT&T and ask for assistance with making sure your Xbox is not being filtered out. The console's MAC address can be found under the Advanced settings so have that ready when contacting your provider.
