I have problem with WiFi module. When I boot system I get following messages

However all interfaces are shown as disabled in LUCI. I use 20V power, 12V switch is turned on and the LED for M.2 slots is on.

Happens to me sometimes. I have the Pro 4E preassembled. Have you tried restarting (not powering off) and seeing if the WiFi card comes up. You can use the reboot command from within SSH or the serial console.

It seems to happen every time.

Try this:

echo 1 > /sys/bus/pci/devices/0003:01:00.0/remove
sleep 4
echo 1 > /sys/bus/pci/rescan

If it works, please post back here.
