Not sure how best to describe this but I've recently moved my Home Automation to a different system and been more 'aware' of any network activity, devices not available, dropping off etc.

Today at 4pm though my secondary node in an AiMesh seemed to drop off, I'm not sure why or how but the logs are as below, any ideas what happened and where/what I need to look at next?

This is from the RT-AC68U (node)


On the main node RT-AC86U I can't see much if anything to do with the issue in the syslog.
I know it was down as I lost devices and in the AiMesh GUI it showed as down etc

Both are running 386.2

That's because it contains banned word combinations. e.g. /etc followed by /hosts.

Tweaked, bit of a daft rule?

Adding as the code direct in a hope it might get looked at.

The log doesn't show anything particularly helpful, only what you already know. The network interface (192.168.1.45) disappeared, briefly failed back to 192.168.1.1 and then reconnected.

Looking at the log it did it 03:48, 05:50, 06:56 & 14:03 on the 12th, 21:00 on the 10th, logs vanish prior to the 9thh.
There doesn't appear to be anything in the logs prior to this happening.

Any ideas, anyone?

I've done a factory reset of the node and re added to the AiMesh.
See if it behaves better.

Having just experienced this once again I quickly diagnosed it looks to be my TP-Link powerline AV adapters I use for the backhaul.
It's been pretty much flawless for nearly 2 years.
Power cycled both ends, found a slightly newer firmware and updated.
Fingers crossed.
