Mediatek driver failure

After rebooting, Network manager doesn't detect my wlan interface and the GNOME network manager wi-fi setting vanished. Firmware version is ____000000 for some reason so I tried using linux-lts kernel and reinstalling linux-firmware, but the error still persists.

sudo lspci -k | grep -A3 -i network

Re: Mediatek driver failure

Don't grep - the NIC seems to show up and operated by the relevant module, nothig there really explains problems.
But there's a recent problem w/ the MT latest firmware, https://bbs.archlinux.org/viewtopic.php?id=308360
