We have about 60 Panasonic CF53s with EM7750s that we are trying to upgrade to Windows 10 1903, but after the upgrade the modules show as “Turned Off” every time the system boots. The only way to get them to turn back on is to flip the hardware WiFi switch on the machines off and back on again.
I called Panasonic and they told me it was a Sierra Wireless issue and there was nothing they could do.
I have the latest USB Drivers (Build 4836) and firmware for the card (126.96.36.199). Has anyone experienced this before and managed to resolve it? We are no longer legally allowed to keep these machines running 1809 because of security purposes, so not upgrading to 1903 is not an option.
