AX1800 model RAX20 disconnecting every day at the same time.

I have had the AX1800 RAX20 router for approximately 2 weeks. Ever since I hooked it up, the wifi disconnects at the same time every day. Every night at 8:13 to be exact. Every day since I plugged it up. My kids say it happens in the mornings too, but I cannot confirm that. It will knock everyone offline for 2-3 minutes and then come back online and work fine. Any suggestions on what could be causing it and what I can do to fix it? The modem is a cable modem, that was updated a few weeks before I purchased this router.
