I've successfully connected to my phone's hotspot for Internet so I know it's not the hardware in my PC.
I'm using wpa_supplicant and NetworkManager. I tried swapping out wpa_supplicant with iwd since I have an Intel board, but that didn't fix the issue either. The issue may rest with NetworkManager.
I'm able to connect to my home wifi router with other devices such as my phone and various other windows computers. This pushes my next point.
Either this is some crazy mass anti-Linux Mac filter from ISPs or NM had a bad update. I'm convinced it's the latter. I experimented with changing the Mac address on my Linux PC and I was able to connect to my home wifi router for a bit until I changed something else. Now, whether I change the Mac address or not, the connection will not work.
I'll post some journal bits later, but most of the entries looked like blatant refusals to connect by the access points. Failure to complete 4-way handshake.
My wifi router supports the following:
2.4G band - WPA2 and down
5G band - WPA3-Transition and down
6G band - WPA3 (Personal only)
I just downgraded NetworkManager, and that seems to have fixed the issue. I don't know what happened with that, but NetworkManager may have been the culprit. I'll look through the diffs between the last couple weeks and let you know if they did anything major.
