NET light not coming on

NET light not coming on — Incorrect Wi-Fi password entered

Mitsubishi Electric · Wi-Fi Interfaces

What does NET light not coming on mean?

During Access Point (AP) mode setup, if you enter an incorrect Wi-Fi password for your home network in the app, the NET light on the Wi-Fi interface will not illuminate, indicating a failure to connect to the internet.

Common Causes

  • Incorrect password for the home Wi-Fi network was entered in the app.
  • Attempting to connect to an unsupported Wi-Fi frequency (e.g., 5GHz instead of 2.4GHz).

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Double-check your home Wi-Fi password for accuracy.

  2. 2

    Ensure you are selecting the 2.4GHz network if your router has multiple bandwidths.

  3. 3

    Restart the AP mode setup process from the beginning.

  4. 4

    If issues persist, try temporarily simplifying your Wi-Fi password (if possible) for testing, then change it back.
