Xbox series X keeps disconnecting from wifi when i power it off.

I bought the Xbox series X recently. Every time i turn off the xbox, it disconnects from wifi. So none of my games ever get updated and i have to manually connect every time i power it on. Ive troubleshooted everything on my wifi and it says nothing is wrong. I’m curious if this is an xbox issue or ATNT wifi issue. I’ve looked through settings and i can’t find anything about it. my automatic updates are on but the xbox itself disconnects from internet completely. Any help would be greatly appreciated!
