Aimesh node keeps restarting wireless

[bones20]

Hi All,
I have an Aimesh setup at home for the last 2 years:
APs (RT-AC68u) * 2
Firmware: 3.0.0.4.384_45717 (although tried all including latest)
Config: Fixed channels, 20MHZ for 2.4ghz, disabled these (airtime fairness, beam formations (except ac), Nat acceleration), everything else default.

Since the last 4-5 weeks, I am seeing jittery wifi near the Aimesh node in the bedroom. I see the below logs when that happens. I have tried everything I could think of including rebuilding from scratch, different firmware versions, reducing radio power etc. Why does the rc_service daemon keep restarting the wireless 5/6 times a day?:
Apr 4 12:07:45 rc_service: amas_wlcconnect 22852:notify_rc restart_wireless

At this point, I have given up and planning to buy a new system unless somehow here has a clue on how t solve this problem. Thanks in advance. Your help is much appreciated.

Should it be scanning if you are using fixed channels?

OE

No idea

 

[bones20]

for 5 GHZ, extension channel is set to AUTO (no other option)
channel bandwidth is 20/40/80

I use:
- set 2.4 WLAN to n-only, 20 MHz, ch 1,6,11 or 1,5,9,13 (non-overlapping, least congested), WPA2-Personal AES
- set 5.0 WLAN to n/ac mixed, 80 MHz, ch 149 or above (US, non-radar, highest Tx power), WPA2-Personal AES

I tried the fixed bandwidth 80MHz. Still see the acsd scan log messages. Rest of my configuration is same as yours.

Given it worked for two years and is now acting up, maybe a router is failing.

thanks @OzarkEdge thats what it seems like.

Before you give up on the hardware, see if a full reset helps.

Please see the link in my signature below for the M&M Config and the Nuclear Reset guides.

The following links may also be of use to get your router back to a good/known state.

If after following these suggested steps the issue is still present, without any of your specific customizations in place, then a hardware issue is more likely the real problem.

HTH.

Just Fyi, the problem seems to have gone (17 hours so far) after I replaced the power adaptor. Will be able to confirm if and once this is sustained our few days.
