AiDetection alerts (Asus RT-BE86U)

[Carnivore]

I have an ASUS RT-BE86U, 6 months old with the latest ASUS firmware. I use it as a standalone router, not in a mesh configuration.

I frequently get these alerts from the ASUS Router mobile app.
First:

AiDetection
LAN port 2.5G WAN/LAN-1 of RT-BE86U (Home) is disconnected.​

And then immediately after that:

AiDetection
LAN port 2.5G WAN/LAN-1 of RT-BE86U (Home) is connected.

I searched for the cause of this and was surprised to not find much about it. Is this the router blocking malicious attacks and if so, is it routine activity that can be ignored? Or could it be a problem with the LAN port, a cable, a device on my network, or something else?

I don't actually notice any interruption in connectivity on any of my devices when I get these alerts. They have persisted through numerous firmware updates but I don't remember if I was seeing them when I first got the router.

possibly a bad cable between the modem LAN and the router WAN ports. Or a flaky/dirty/misaligned wire fingers in one of the ports.

Thanks, I guess that answers my question about whether it's malware detection or hardware related. I'll change out those cables. The alerts have come intermittently so I'll have to wait and see if that solves it.

That LAN port is connected to a switch that feeds some desktop PCs, Roku streaming devices, a Ring alarm base station and a SmartThings hub. I hope it's not a flakey cable somewhere downstream.

It's marketing related. Connectivity monitoring was there before, now called AiDetection.
