Question

Mikrotik

When disconnecting the provider cable from the MikroTik hAP ac lite router and connecting it again, there is no connection to the provider's network, you need to manually restart DHCP. the same happens when the power is turned off. What to do so that he himself restarts the server when power is lost or the provider's cable is disconnected

Answer 1

Probably at the provider authorization through DHCP is made. As practice shows - a thing with a certain degree of curvature. If possible and necessary, it is worth working out this issue with the provider to change the authorization method. If not, then you can draw a script that checks the availability of the provider's gateway (default gateway) and resets the interface address (dhcp release) if unavailable. Sometimes dhcp renew helps (in theory it should work a little faster). Execute the script through the scheduler with your favorite frequency.
