Xbox series x shut off and won’t let me reconnect to 5g wifi

My console is the Xbox series X. My controller stopped working last night while I was playing a game and it said reconnect controller but it was still on. I’ve tried holding the pairing button but nothing happened. I’ve tried taking it out of range of my Xbox to see if it would shut off. I’ve tried restarting and unplugging my Xbox. But my elite controller still has the light on and won’t do anything. Even the button to change paddle presets isn’t turning those lights on.

This did not work, I also noticed that if I shut off the XBOX One X it disconnects this controller and I have to reconnect it on startup. This does not happen with my other controllers just the Elite series 2 one.. I'll request a replacement

Thankyou for the response, I have other things connected to my WiFi and are having no issues with them so my WiFi is on and working, I even pulled out my Xbox one and it’s having the same issues, I’ve reset my Xbox series s, and It won’t even let me finish the setup stages because it just simply won’t connect.

The problem has started this week my console is a series S and it's works on my neighbors 5G wifi

Hi there (sorry for my english mistakes)

I have probably the same issue.

When I start or restart my Xbox one X it doesn't connect to my wifi network. The name of the wifi network is written but there is no connection

I have already try :

- To restart my router ==> I didn't change anything for month and it worked well with my first xbox one and my actual xbox one X before this issue. All my other devices (smart tv, phone, computer) are well connected to my wifi

- To reconnect the xbox one x to the wifi with Settings / system / network / disconnect and then new connection

- To power cycle the console, holding the start button for 10 seconds until the console shut down and disconnecting and reconnecting the power cable

- To restart after clearing the mac adresse

- To do a factory reset ==> The first start after the reset, i can reconnect the console to the wifi network (so I think I have no issue with my router), but if I shut down the xbox or restart the console. I lose the network. I have to do a new factory reset
to reconnect the console

Thank you for your help.
