Last couple of days I noticed my teams meetings / online games will disconnect every once in a while. Today I finally looked at my router log, it seems internet is lost every 80 minutes, each time for 15 seconds.

Those logs could be down to something on the modem. They show nothing in the way of action at the router end. What do you see when this happens? Is there an LED on the modem that you can check? What is that modem? What firmware is installed on the router? Just another user with time on their hands.

Could be yes, but last night I decided to reset only the router and left the modem running (modem is Comcast Gateway), and the issue is gone.

Does the front Internet LED on the RS turn AMBER or RED when this happens? If it does, means the RS is not getting a good signal from the ISP Modem or Gateway. If your ISP Modem already has a built in router and wifi. This would be a double NAT (two router) condition which isn't recommended.

Now that the problem is gone I can't check it anymore. But the modem is already in bridge mode. Regardless, I can't imagine what kind of issue will cause precise internet disconnect every 80 minutes, almost to the second.

Ya thats a odd one for sure. Glad the factory reset seemed to help. Wondering if some odd issue got the modem or router or both in some bad state. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.https://kb.netgear.com/24231/How-do-I-back-up-the-router-configuration-settings-on-my-Nighthawk-routerEnjoy. 📡
