Xbox Series X wifi connection issues

I got my xbox series X about 24 horus ago and since then have not been able to do anything. I initially set it up with the xbox app and when i started to download assassins creed valhalla, even though the console was connected to the internet it stopped
doing anything. The wifi is working fine on all other devices in my house. I cannot download any app, game or look at the store even when connected to the internet, and it frequently signs me out of the xbox. I have noticed that the bandwidth usage never goes
over 1 mbps except in the ine scenario listed below.

Since then i have tried all troubleshooting steps (restarting console, power cycling, full reset) except olugging the console directly into the router because i do not have an ethernet cable.

At one point i un-paired my wireless headset and it seemed to work for a few minutes before i re-paired the headset and it stopped again. Since rhen i have had no luck whatsoever. At this point i think i might need the console serviced or replaced but wanted
to check here before trying to send it back.
