Xbox is no longer connecting to the internet.

The Livebox must have had a little reboot from your service provider, and therefore the Xbox may have been ejected from the firewall; re-register it.

Look here for the instructions for your router! ;-)

look, he put everything, read it all the way through

Redo the maneuvers to connect it to Wi-Fi.
If it still doesn't work: try plugging it directly with a cable.

Do a connection test on the Xbox, which will help identify where the problem lies.

If your Xbox is modified and you are using downloaded games, you might also be banned. So you are prohibited from connecting to Xbox Live. Try all of this and keep us updated.

Well, it's all good, it works!! I reset my Livebox to zero and restored my Xbox settings to factory defaults and it's working again!!

Thanks again to you!! Have a great rest of the day!

I've already tried via the button, I can try your second suggestion, how do we do that?

Moreover, when I go to the configuration panel of my Livebox, my Xbox does not appear on the list of connected or previously connected devices.

normally, thomson and sagem are almost identical, try with the one from sagem

Hello

Have you checked the wiring?

I am connected to my livebox via Wi-Fi, and the internet is working perfectly fine.

I don't have any of the proposed routers... I have a mini-Thomson.

Are you sure you still have internet connection?
