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:

GT-BE98 Pro, Firmware Version 3.0.0.6.102_39112

If it is truly 10Mbit/s or 100 Mbit/s, start by verifying the WAN cable to the ISP equipment. Also, check the logs in the ISP equipment.

To clarify, this router is used as an AP?
I'd be concerned about all those failed logins coming from external IPs. Do you have WAN admin access enabled?

No WAN connections in AP mode, the world is the LAN...

@foggdawg01 Comcast service is what type/speed? That is a lot of clients even for the mighty GT-BE98 Pro. If in AP mode Comcast provided a gateway, and it is running as a router? What was the old ASUS router model and was it in AP mode as well?

Then it's not an AP, still seeing attempted logins from the Web - it's in the syslog, if you even bothered to read it. If admin access wasn't open we wouldn't see failed captchas.

Sorry for stating the technicality....

Yes I do see it, but technically speaking all ports are LAN ports in AP mode...

EDIT- More specifically the router gets an IP assigned by a DHCP server or manually assigned as part of the local network. Both sides (of traditional WAN port) are the same Private IP address and it is difficult to access from the WAN side as such.

I had a bad line earlier on a switch and the ASUS ROG told me it was a bad line with the color identifier on the connections. I replaced that wire and it showed green instead of yellow. The modem wire shows green, but I didn't replace it or test it otherwise.

I changed Comcast modem to only be a modem, disabled router and AP so everything would run through the ASUS router. Our prior ASUS router was AC5300. We've traditionally had 80-100 devices. 10-15 are the infrastructure for the system (two directional antenna, 4 switches, 6 APs). A lot of them are phones/watches in the firehouse for the 15-20 guys here each day. And everyone has a smart TV now.... Most of the devices aren't high traffic, but always a lot of devices.

I'm not sure on your question? Yes, I have WAN access enabled for HTTPS on a specific port so I can log in from home and see the router when people say the internet is acting up.
