wireless backhaul fails often.

Note that it’s wl2, backhaul band. One thing that kept the nodes stable longer is setting gtk rekey longer. (Disabling with 0 doesn’t work, it just starts to retry immediately.)

You could try running following commands on main router and nodes.

nvram set wl0_wpa_gtk_rekey=2592000 nvram set wl1_wpa_gtk_rekey=2592000 nvram set wl2_wpa_gtk_rekey=2592000
I tried every combination of settings I can think of, but sooner or later my nodes enter this wpa loop (and there is also a dfs loop that just switch dfs status every second).

Respectfully disagree here... it's a security concern as what you are suggesting is to keep the group keys the sane for a month...

Find another way...

I don’t think this has anything to do with signal/placement. Similar wpa loop happens on xt12 too.

Node logs are not visible to casual user, and no one bothers to check their logs, so the weird stuff keep unnoticed. Some wifi settings don’t sync to them, they try to do site survey every 5 minutes and fail each time, wpa rekey errors, dfs craziness etc…

Well, my issue in this topic is not the connect-disconnect lines. I just mentioned them as a result of your suggestion to run the SSH log command. Or do you think the connect-disconnect issue is related to my instable backhaul connection?

I have stopped smart connect on the router, because my smartphone was switching back and forth from 2.4 to 5.1 Ghz network. Now the ssh command gives me a log without the connect-disconnect lines. Coincidence, or is there a relation between switching of smart connect and the log entries?

edit: the connect-disconnect messages are back on the main router. I see they are related to my smartphone. If I switch wifi off, the disconnect message appears in the log. When I switch it back on, the connect-message appears. Question is: why is my smartphone giving these lines all the time, even if I do not switch WIFI? And why do other devices not give such log entries?

the client device controls which radio it wants to attach to.

Update: the bad signal between the two device (backhaul) seems to be cured. I narrowed bandwidth on the 5Ghz backhaul band to 40, Smart Connection disabled, WIFI Agile Multiband switched on, and Roaming Help disabled. Backhaul is steady for 4 days now. I disabled the nightly restarts (which I had set to force new backhaul connection every night, see opening post). Coming days I will slowly change the other settings to the old values too. Maybe I can discover which causes the issue with the Wifi Backhaul.

The issue with the log entries and some devices disconnecting and reconnecting all the time, I will sort that out later. (that issue still persists, annoying while watching video streams.)
