My home network consists of RT-AX68U (latest Merlin) and mesh node RT-AC68U (latest stock firmware).

Since a while back (a few months) I started having issues with my network and that clients lost connection. Only for me having to reboot the router.

In the attached log after line 991:

"Dec 22 12:03:37 avahi-daemon[1332]: Service "RT-AX68U-4" (/tmp/avahi/services/alexa.service) successfully established."

is where I had to restart the router and then the timestamp for the log is May 5th until time is synced with ntp.

Code:

I notice here that avahi-daemon is having some problems here. And I reckon that Google Nest/Home devices use mDNS and I have issues with those devices disconnecting, restarting etc.
Could it be related?

Asus router in general and Merlin's mod have always worked well for me.

I'm literally out of ideas, so any help troubleshooting would be highly appreciated.
