Do you need to click the "site alias" box under TRS and then populate that list with some data in order for this to function when not set to smart zone? RSSI value on MotoTRBO. I think Meraki APs uses RSSI since I saw positive signal strength values in our data. The RSSI should be greater than -95 dBm, so -90dBm should be sufficient to maintain a reliable signal. It can be programmed for anything between -80 dBm and -120 dBm. Let's get you a stable connection. Setting the AGC to a fixed range prevents automatic ranging from choosing a different setting. I have a Galaxy Nexus, and i know it has weak reception, but looking around at the whole RSSI and RSRP thing, I have found that the -100 to -110 dbm that I commonly see on LTE is actually common and the 1-3 bars on the phone showing for that signal strength is actually accurate and not just the phone displaying bars based on RSSI values from . To do so, configure P0 as RSSI Tags: RSSI, SNR, dBm, Wi-Fi Depending on your OS and application, WiFi signal strength is represented either as quality in percentage, or an RSSI value in dBm, i.e. It's quite easy.
