Hello,
I am having a strange issue with my RT3200 (running OpenWRT 22.03.2) and it losing connection to the WAN every so often. Small brief snippet of log files is below with IP addresses redacted.

I have reset the RT3200 to factory default and the same behavior persists. Currently running it only as a router and have a Ubiquiti switch plugged into Port 1 on the RT3200 and an AP plugged into the switch. Nothing custom at all as far as rules or anything else, purely stock. I have the same issue if I run the RT3200 as the sole device providing routing + WiFi as well. Weird thing is if I substitute the RT3200 for a Google Wifi puck I don't see the disconnecting behavior at all. (I know I can't see log files on the Google WiFi, but the way I have verified this is to keep a stream running all day long and the connection never drops intermittently with the Google WiFi whereas it does on the RT3200)
I am not super savvy with OpenWRT, but I can get my way around with guidance. Any help would be greatly appreciated.
