Xbox series X won’t connect to my router

I’m having the same issue. I got a series X about 2 weeks ago and it won’t stay connected to WiFi. It usually will only hold connection for a few minutes, anywhere from 2-20 maybe? A couple times it has maintained connection for multiple hours though that is very rare. It sits next to my Xbox One X and a few feet from my PS5, all of which connect to the same WiFi network without issue. Due to location of the router, a hardwire connection isn’t possible.

Given that connect was not that much of a success it probably won’t have one but they haven’t said anything if you will be able to use an Xbox one connect on Xbox series X so hopefully you can

My Xbox X series just said update an I pressed update console but it won’t update

I have same issue but with my Acer Nitro VG271 144Hz. Xbox series X won’t run at 120Hz 1080p. That must be problem with xbox series x because works perfect with Asus RX480 8GB (144Hz 1080p HDMI2.0). I am very dissapointed. 60hz is a joke.

So just to double check - if I get a Series X and I plug my hard drive into it, I won’t be able to play MWII? I will have to re purchase the game as the Series X version?
