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).
