I was having this issue for a couple of months now and I thought that it was optimum dropping internet connection so I switched to Verizon for fiber internet and I opted out of getting a router with Verizon so I only have a modern with no router or WiFi capabilities. Also I have the r2 and as for how constant it happens sometimes it will be back to back and sometimes I’ll be fine for a week.
I am experiencing constant connectivity issues where the Wi-Fi and internet drop off for a couple of minutes and then come back. I've set the lease time to 168 hours, assigned static IPs to my main devices, and turned off IPv6.
