LABEL DESCRIPTION
RSSI (dBm) The RSSI (Received Signal Strength Indicator) field shows the WiFi signal strength of the station's
WiFi connection.
The normal range is –30 dBm to –79 dBm. If the value drops below –80 dBm, try moving the
associated WiFi station closer to the WX Device to get better signal strength.
SNR The Signal-to-Noise Ratio (SNR) is the ratio between the received signal power and the
received noise power.
The normal range is 15 to 40. If the value drops below 15, try moving the associated WiFi station
closer to the WX Device to get better quality WiFi.
Level This field displays a number which represents the strength of the WiFi signal between an
associated WiFi station and the WX Device. The WX Device uses the RSSI and SNR values to
determine the strength of the WiFi signal.
5 means the WX Device is receiving an excellent WiFi signal.
4 means the WX Device is receiving a very good WiFi signal.
3 means the WX Device is receiving a weak WiFi signal.
2 means the WX Device is receiving a very weak WiFi signal.
1 means the WX Device is not receiving a WiFi signal.
