Rock 5C - WiFi stops working after system upgrade

[oqewipobin]

I'm having an issue where the prebuilt images dowloaded from https://www.armbian.com/radxa-rock-5c/ (released on Oct 12, 2024) works fine, including WiFi connectivity, even after reboots, but the moment I updgrade the packages (apt update && apt upgrade) and reboot the system, the WiFi network interface (wlan0) simply disappears and can I no longer search or connect to any wireless network.I've flashed both Bookworm Minimal/IOT and Server/CLI Bookworm, e the issue always occur after upgradin packages.

 

the wlan0 does not appear on iwctl neither ip address commands, but the device (AIC Wlan) still appears on lsusb command:

$ lsusb

I don't know if there is an issue with the newest kernel update, or if there is some overlay or kernel module for the AIC Wlan chip that is being erased/disabled during the kernel update process.

Is there something I can try to reenable the wlan0 interface? or is it just a bronken update?

Looks like installing/reinstalling the Radxa provided packages for aic8800 (https://github.com/radxa-pkg/aic8800/releases) kernel modules AFTER the kernel update makes the WiFi module work again.
