So I was able to confirm that the drivers loaded for all three adapters (using dmesg | grep usbcore) but I got some errors when trying to modify the wpa_supplicant.conf file (via nano and vim) - it’s giving me a Read-only file system alert.
Tried a chmod with no luck either even though we’re root. Is there a form of chroot jailing going on with the underlying OS that would prevent a normal user from modifying files (even though it shows we’re root)?
Tried using your previous ip link set wlan0 up and wpa_supplicant commands with and without the driver flags to no avail, tried to just pass the creds via wpa_passphrase too. It says that it initializes properly but when I try to do anything with it I get a Failed to read or parse configuration 'etc/wpa_supplicant/wpa_supplicant.conf'. Tried to create a dummy .conf too but ran into the Read-only file system alert again.
I’d be happy to dump some logs up here if that helps. I’m a network guy by trade and no stranger to Linux (though this is my first time in Arch in a long time) so I’d be happy to troubleshoot with you.
