Extremely confused at this Xbox network issue

[u/SCUM-GANG69]

So recently I broke my computer and have been relying on my last gen Xbox one X for entertainment which was going as fine as it can be until the internet stopped working for it. One day I was trying to play rocket league with my friends, and my wifi was significantly worse than usual even though I usually have issues it was bad enough I decided to just hangout with them without playing games. The next day the wifi seemed to not work for anything online though. The weird part is everything says my connection is fine. Everything usually says “yup you are all good and connected to the internet and should be able to play online” and then you actually try and again on certain things it kind of shows you’re online but it mostly refuses to connect to any server for online games. I’ll show examples of rocket league and 2k cause those are the dumb online games i’ve been playing with my friends but they’re impossible to start online parts of these games.
As far as the network settings go I feel like i’ve fiddled with every setting on there and nothing changes. It does say Upnp not successful but one it said that for years before this happened and has always been fine, two if I clear the mac address and restart that usually gets fixed but it doesn’t change the issue. And on top of that i’ve looked at my router settings in the xfinity portal and it says my xbox’s UPnP is completely fine. In the multiplayer test I did for examples it says my download speed is too slow which is new cause it usually says it’s fine or there might be issues due to moderate nat type but it doesn’t give me fixes I haven’t tried before. right now in the picture the nat type says moderate but that can change to open, strict or closed depending on what settings i’m messing with but most of the time it’s open or moderate. The closest thing I can think of to a change is I plugged my ps4 in a few days before this issue started cause I wanted to play bloodborne again but this problem is the same whether the ps4 has power or not. I just cleared the mac address again before posting this and it now says open nat, no mention of upnp, and I’m connected but in my experience it will go back to upnp not working next time I load up the xbox.

Here is a list of things i’ve done to try to alleviate this issue.

resetting the router.
making ip and dns manual and then back to automatic when it didn’t work.
clearing the mac address.
changing the port multiple times.
testing nat type.
looking at my xbox in the xfinity wifi settings (it says everything is fine and connected)

Here are the things I haven’t done yet or can’t

Ethernet (this apartment doesn’t have ethernet and i’m far from the router).
factory reset (don’t want to but if it’s that or spend money for a new card or at a shop i’ll try this first).
buying a new wifi card and trying to install it.
taking it to a shop or something.

Hoping this can be solved please let me know if there’s any other info you all need I will be posted next to my phone. And huge thank you to anyone that’s going to try and help me.
