Wifi Suddenly Stopped Working

My Wifi on my XPS 13 (9310, AX500 chipset) suddenly cut out this morning and would not come back on. The wifi works on Windows but does not in Manjaro. Issues persist through kernel change reboots, complete shutdowns, etc. wifi-menu gives me a “invalid interface specification,” and rfkill list all gives this:

        Hard blocked: no

lspci -k (the important part)

^ no kernel driver in use, but i’m not sure what to do about that

Lets start with

sudo modprobe ath11k_pci

(and post results, if any)

But I dont expect much there.
Then we have the ‘hail mary’ of adding this to boot options


If you dont know how … add that code to /etc/default/grub on line GRUB_CMDLINE_LINUX, like so:


Then run

sudo update-grub

and reboot.

sudo modprobe ath11k_pci
no results
added memmap=12M\$20M to GRUB_CMDLINE_LINUX
when picking manjaro in GRUB my system goes to a black screen and does not boot - windows works fine

sudo dmesg | grep -i ath11k gives this:

[    2.241520] ath11k_pci 0000:72:00.0: BAR 0: assigned [mem 0xa2500000-0xa25fffff 64bit]

ok update:
i reset my bios settings to factory defaults (i’m not sure why this changed anything, i haven’t touched my bios in forever) and wifi has reappeared
