No network after router reboots

Whenever my server loses its network connection if my router gets rebooted I can no longer connect to it without plugging a keyboard in and hitting ctrl alt delete to reboot rockstor. How can I make fix this?

Do you use static pour
or dynamic IP Adressing?

I’m using DHCP reservation on my router to give the same ip each time.

Just Set the ip static on Your Rockstor NAS. Observe it for some days.
