What does Amber Blinking LED mean?

Zyxel_Support

When LED is showing Amber Blinking, it means Multy U (WSR30) is upgrading the firmware.

There are 2 possible situations for firmware upgrade:

1. During installation, the WiFi system will check the firmware version and will trigger the firmware upgrade procedure for the Multy unit if the firmware of the Multy unit is not the latest version.
   
   
2. After installation, the WiFi system will check the firmware version while Muylty app is opened. There will be a pop-up message shown on the Multy app to ask for upgrading the firmware of Multy U (WSR30) to the latest version.
