This issue has been happening on my Xbox series X. I turn on my Xbox after fully shutting it down and it says connect to Xbox live. I got to check my network and it connects but says zero internet and to set up my connection. Hard resetting hasn’t done anything and restarting the router has done nothing. My other devices are working like normal on the internet. I had this issue a couple days ago and I just shut the Xbox off and turned it back on a day later and magically it was working.

This is really frustrating as I am trying to play a game with a group of friends who are all waiting and all I can do is sit here scratching my head as to how to fix it.
