Why does my mobile router switch to 4G backup mode?

Zyxel_Jami

The WAN Backup feature on the Zyxel router is designed to ensure continuous network connectivity. When the wired connection is unavailable, the router switches to an alternative network. It uses a configured IP address to check Internet accessibility at specified intervals to determine the connection status.

To resolve this issue, please verify the 'Connection Check' parameters to ensure they are set according to your requirements.
