Automatic maintenance enables you to make the router restart regularly. It helps improve the
stability and service life of the router.
To configure the automatic maintenance function, choose Administration > Device Management.
When this function is enabled, during 02:00 to 05:30 every day in the morning, if there is any user
connected to the router and the traffic over the router's WAN port exceeds 3 KB/s within 30
minutes, the router will delay rebooting. If there is any user connected to the router and the traffic
over the WAN port does not exceed 3 KB/s within 30 minutes, or there is no user connected to the
router and the traffic over the router's WAN port is slower than 3 KB/s within 3 minutes, the router
will reboot automatically.
