Xbox one authentication?

Last week I played online and since Saturday I'm no longer in the xbox live purely and when I test network connection is because authentication required

Then 2 options

1. Now authentication (nothing happens)

2. Alternative Mac address enter that I can't no idea how that works

Can someone help me it's important (Rocket League and such)

Thank you

Have the solution!

So on the Xbox you choose alternative MAC address.

Then you open CMD on your computer.

There you enter ipconfig / all.

Your MAC address should be listed as a physical address under the Ethernet Adapter Section.

You then have to enter this found address and it should work.

Please let me know if it worked;)

What is computer cmd?

Okii yes I'll try everything afterwards kla

Maybe that will help you

Did it work but unfortunately not thank you
