- detect that firmware cant stay connected to 5GHz AP and tune down 5GHz preference accordingly
- use a long random string so as to obfuscate PSK of WiFiConfiguration we have deleted but keep around in the autojoin database
- if autojoin doesn't find a known network to join, and sees a known network that ConnectivityService never marked as UNWANTED due to bad signal, then add a boost of up to +8dB to this network's autojoin threshold, also includes the boost in the network's score that is sent to connectivity service
