Scheduled Reboot R7800


Can anyone help me set up a schedules reboot, using OpenWRT on my Nighthawk R7800 I get between 1-2 weeks of stability then usually the Internet or WiFi stops and it requires a reboot. Sometimes it doesn’t come back up from a soft reboot and needs the button pressing. I’m hoping that with a weekly reboot at say 03:00am on a Sunday will be enough for smooth operation. Is there a gui that I can install for this or a command I can use?


use "cron" to schedule reboot
