Fixing Wi-Fi Error E-24

This code points specifically to a wireless setup authentication failure.

Step-by-Step Wireless Setup Fix:

  1. Use 2.4 GHz Band: Verify your router broadcasts a 2.4 GHz network name (SSID), as 5 GHz-only networks are not supported.
  2. Re-enter Security Key: Go to Settings > Network Settings > Wi-Fi > Wireless Setup Wizard on the touchscreen and re-enter your WPA key (case-sensitive).
  3. Router Power Cycle: Reboot your Wi-Fi router to clear dynamic IP assignment deadlocks.

Steps to follow

  1. 1

    Open network settings

    On the printer screen, navigate to Menu > System Settings > Interface Settings > Wi-Fi.

  2. 2

    Select 2.4 GHz SSID

    Choose your 2.4 GHz wireless network name from the detected list.

  3. 3

    Re-enter network passphrase

    Carefully type the exact security password and hit OK to establish the connection.
