Wifi Stops working - Ubuntu 22.04 OS

Hi, we have purchased over 20 lattepanda delta 3 units now. We run Ubuntu 22.04 OS. We have had 3 units wifi stop working. By stop working I mean that the OS has been unable to register that there is a wifi device. It does not appear as a network device/interface

Upon inspection, we can see that the hardware is seen but the OS using the nmcli command but it does not recognise it or activate it.

This has happened to 3 units now, with all of them working before and then randomly on a bootup, the wifi has stopped. 

This is very concerning but most of all annoying as we embed these lattepandas as part of a remote device which connects to a wifi access point. The lose of the wifi functionality is a deal breaker.

Thanks. looking forward to some positive support.
