Since updating my FP2 to Android 7.1.2 (FP Open 18.10.0), it won’t connect automatically to saved wifi networks. I have to turn wifi off and on again for it to look for networks and connect to the saved ones. Happens with different networks so it has to be a problem with the FP.
I have the same issue. Sometimes turning the wifi off and on again is not sufficient, i have to reboot the phone to make him connect to the saved wifi networks.
