Wi-Fi signal strength
Wi-Fi signal strength is measured in decibel-milliwatts
(dBm). The signal strength of the network you are currently connected
to is usually represented graphically by a Wi-Fi symbol.
The signal strength range represented by each filled bar is determined independently by each device manufacturer. However, in general the performance will be similar.
1/4 — Unable to maintain a connection, usually accompanied by very poor connection speed (LightHouse™ MFD: –150dBm or worse).
2/4 — Intermittent disconnects and reconnects, usually accompanied by a slow connection speed (LightHouse™ MFD: –80dBm to –149dBm).
3/4 — Reliable connection with good connection speed (LightHouse™ MFD: –70dBm to –79dBm).
4/4 — Reliable connection, excellent connection speed (LightHouse™ MFD: –55dBm or better).
