Thanks Patrick. I was aware of those ranges, but more specifically confused why we are getting a 5 digit figure from Particle instead of a 2 to 3 digit figure which corresponds to the charts you link. Any ideas? Are we doing something wrong?

If you're using system firmware 0.8.0-rc.x on Wi-Fi device (Photon or P1), there's a change in the API that is particularly noticeable if you're passing the result to sprintf/Serial.printlnf/Log.info:

I just ended up using WiFi.RSSI() like @rickkas7 suggested:

int rssi = WiFi.RSSI().rssi;
float signalQuality = WiFi.RSSI().getQuality();
