Wifi interface seemingly disabling itself?

When I booted my laptop today the Wifi suddenly wasn't working and I've been trying for the last two hours to make it work again. I think I fixed an issue or two down the way but I didn't really document anything. The problem I'm unable to solve now is this: My Wifi interface seems to be disabled and I can't (always??) enable it. But even when I was able to enable it the Wifi still wasn't working.

This is my output of lshw -C network:

The first is my Ethernet connection that I don't use. The second is my wireless connection that miraculously stopped working today. The third is my workaround Tethering connection through my Phone.

modprobe -r iwlwifi and modprobe iwlwifi didn't work first, now they do but it didn't really change anything Also, when I try sudo ip link set wlp2s0 up sometimes it switches the interface to enabled (sometimes it doesn't), but still, Wifi isn't working.

I'm running Ubuntu 20.04 LTS on an Acer Travelmate P236-M-57R4. Thanks for helping in advance!

Edit: Don't know if there is any connection, but I had some issues yesterday with the very unwise decision to chown -r my /usr/-folder with my main account. I think I resolved these, but maybe I didn't?
