I had the same issue with my module and i’ve found that if I remove the file “/etc/dnsmasq.d/dnsmasq.wlan1.conf” and reboot it, i’m able to get an IP from the Network adapter (CF3 USB).
You can achive this by putting the DIP switch 6 to the OFF position and opening a serial linux console (USB Console with a 115200 baud rate).
Hope it will help !
