Hi,
I have an APU2C4 with two wireless modules: WLE200NX and WLE600VX by Compex. Yesterday, I upgraded the firmware from v4.11.0.2 to v4.11.0.5 and performed a cold boot (shut down, pulled the plug, waited a few seconds, put it back in and booted). After rebooting the WLE200NX wifi module did not come up again. The second wifi module worked fine. There was no error during boot (other than hostapd complaining about the missing device). And a second reboot did not make any difference. The command 'iw dev' does not show the WLE200NX device, either.
I downgraded to v4.11.0.4 and now both wifi modules come up again just fine. So, there seems to be a clear regression in v4.11.0.5.
My OS is Debian 10.
Regards,
Timo
