Intermittent Internet Connection Issue

[foggdawg01]

Hello all, New here and we just installed a ASUS ROG router/AP. We have comcast internet fed to the ASUS router. The router has LAN connections to three switches. The switches all have several LAN connections as well as 5 different APs throughout the building. The ASUS ROG is also setup as an AP. We had an older ASUS router for years that worked well but we were having some issues. I assumed with errors on the router log it looked like the memory was going bad and I didn't want to risk formatting it and setting up the router, having somehting go wrong and be dead in the water with angry people not having internet. Installed the ROG router, set it up, it looked like it was working good for 48 hours then I started getting phone calls about intermittent internet. Speed tests look great for most times (500+ MBPS) but occassionally it'll go to 10 and then come back up. Upload speeds tend to do the same occassionally. Below is the log but it looks like there's a couple errors and I don't know why. I read somewhere else about turning off all the other services to troubleshoot it. I turned off traffic analyzer, QoS, AI Protection, and everything else I can think of. It's so intemittent I'm not sure how to trouble shoot it. All help would be appreciated:
