We live in a residential sub-division, which has approximately 6 networks. However, the wifi signal test outside the house, next to the Ring Pro doorbell is weak, with a signal of -75dbm, on the 5Ghz band. The wifi signal test inside the house at the front door shows a strong wifi signal at -65dbm on the 5 GHz band. For example, if the RSSI provided by a receiver has dynamic range of 92 dB (from 88 dBm to +4 dBm), the minimum signal energy the receiver can measure is 88 dBm. My gateway, an AT&T U-verse Arris BGW210-700 (with voip telephone,iptv, dvr, DVR, ip internet) is in a straight line path, approximately 25’ from the front door. The RSSI dynamic range is specified in dB and indicates the minimum and maximum received signal energy that the receiver is capable of measuring. I’ve tried disconnecting some WiFi devices with little improvement in RSSI. We have several wifi enabled devices (Amazon Echos, Alexa, Kindle, as well as computers, phones, android cells, etc.) throughout our house. The Ring Pro’s RSSI shows a value that fluctuates between -61 and -75. I recently installed the Ring Pro Doorbell.
