MODE light flashes orange once every second

MODE light flashes orange once every second — Interface is in WPS pairing mode

Mitsubishi Electric · Wi-Fi Interfaces

What does MODE light flashes orange once every second mean?

The orange MODE light flashing once per second means the Wi-Fi interface is actively trying to connect to your router using WPS (Wi-Fi Protected Setup). This mode is used for simple, button-press pairing.

Common Causes

  • User initiated WPS pairing mode by holding the MODE button for 2 seconds.
  • Router's WPS function is not active or has timed out.

    Check that the NET light starts flashing alternately with the UNIT light after connection.

  4. 4
