Xbox series x connection problems

Hi there. I have tried almost every possible method of restarting, resetting and everything inbetween. Ports are forwarded, etc.

The thing is, I have my Xbox One and Series X set up beside each other. Due to the Series X’s problems, I can switch off my Series X, and switch on my Xbox One, and have no connection issues.

Both playing on the same wifi, both wireless connection, with all the same settings (except the Series X is running on 120fps).

Something is not right with the Series X and I believe it’s more than just needing to reset my MAC address...

I have the same problem, I can't connect to Xbox Live on the Xbox 360 games (on my xbox serie x) since few days 🤔 I precise I don't have any problem on the Xbox serie X games, I have that only on the Xbox 360 games.

My internet is perfect too (I live in Belgium)

The Xbox factory reset on the series X still did not work, it wouldn’t connect to the network. I connected my original Xbox one (2014) back up to my monitor and I was able to play online games just fine on there, same Microsoft account and internet that the series X was not connecting too. My Xbox series x keeps saying it has a hardware issue when trying to connect the internet, I’m pretty sure this proves it’s a physical problem with the hardware on my Xbox. I still have warranty on it and can return it and trade in for a new one. I’ll try doing this and seeing if the trade in one works.

The problem is not with any XBOX console, but when you use the headset with Windows 10. Only on PC you have such problems.

Yes, it's connected with xbox wireless adapter.

I have XBOX SERIES X and there is not problem there.

All I know is that the only console I own that has this problem is my Xbox Series X. I have no other issues with anything else. My phone, my roku, my ps5, my switch. Everything else connects to my network just fine. This is a problem the Xbox Series X has had since it came out.
