If it was just 2.4 I wouldn't need the mesh at all. But these thick cabin walls play hell on the 5 band. The 5 drops way off in the corner of the basement and connections often fail and are very intermittent. The router is at one end of the 1st floor and the node is mid floor in the basement, separated by about 4 layers of thick wood. From about middle it's -64 dBm to the router and -51 dBm to the node.
I can't afford the router downtime at the moment. I do plan on resetting the router if these symptoms continue. I've done it several times over the last year and it never made a difference.
Yes. All Trend Micro features are enabled.
Yes, all 3 boxes have been tested for weeks in a sole router mode. Performance is great (except for the dead spot in the basement) and identical.
Mid day today the router started logging these lines every couple of seconds for over an hour:

1 is the node so something between the router and node got hosed. I did a telnet reboot on the node which fixed it. It's quiet again.
BTW, Roaming Assistant is off. It caused attach thrashing on a couple of Android phones so I had to disable it. I played with the dBm a few times, but could never get to help roaming without causing more problems than it fixed.
