How do u fix additional authentication needed

Hello!

I'm a Independent Advisor. I will be glad to help you.

One of the possible reasons why a console cannot connect to the Internet is because its MAC address has been blacklisted by the router, i.e. someone may have configured the router so that a particular device does not consume bandwidth.

Formatting the router to its factory settings may help.

You can also try a reset by keeping games and applications on the console to rule out that it is a console problem.

Go to Settings>System>Console Information

And restart keeping your games.

Note that the console accounts will be removed, so you will need to have the email and password for each account to log back in.

Your progress, achievements, purchases and other data will remain intact, don't worry about that, you won't lose any data, the only thing you need to do is to log in again.

I hope the information has been clear, I will be attentive to any questions you may have.

Best Regards.

Hi Christian L! I hope you are well, delighted to be able to offer you my help!

This is a problem that is a bit easy to solve, don't worry. The most common steps to solve this problem are:

- Power cycle your router and Xbox console
- Delete alternate MAC address
- Use your router's MAC address
- Restart your Xbox console
- Contact your ISP for help

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.
