To access the configuration page, log in to the web UI of the router, and choose More > System Settings > System Log. 

This function logs all key events that occur after the router is started.

If you encounter a network fault, you can turn to system logs for fault rectification.

If necessary, you can also export the system logs to your computer by clicking Export to Local.

TIP:

Rebooting the router will clear all previous system logs. So remember don’t do it if you want the router’s activity log.
