I searched all over the place for this issue, and never saw a clear cut thread - to the point I spent significant time of trial and error to figure this out. I hope this will help someone out...
Setup:
Issue:
I saw several messages in my router's log that my AiMesh node was frequently disconnecting and my router was re-registering itself.
AiMesh Node was reporting this (forgot to save the entire log portion of this):
Deauthenticated because sending station is leaving
Around the same time my Router was reporting this:
Apr 27 09:37:18 kernel: wfd_unregisterdevice Successfully unregistered ifidx 2 wfd_idx 0
Apr 27 09:37:19 kernel: wfd_unregisterdevice Successfully unregistered ifidx 1 wfd_idx 1
Apr 27 09:37:23 kernel: wfd_registerdevice Successfully registered dev wds1.0.1 ifidx 1 wfd_idx 1

Apr 27 09:37:26 kernel: wfd_registerdevice Successfully registered dev wds0.0.1 ifidx 2 wfd_idx 0
Apr 27 09:37:26 kernel: Register interface [wds0.0.1] MAC: d4:5d:64:0c:XX:XX
Apr 27 09:37:27 kernel: wfd_unregisterdevice Successfully unregistered ifidx 1 wfd_idx 1

Apr 27 09:37:28 kernel: Register interface [wds1.0.1] MAC: d4:5d:64:0c:XX:XX
As a result, this was causing all kinds of grief and instability with my network. Whenever the above message happened, my AiMesh node went completely offline and eventually restarted itself. This happened several times a day.
Troubleshooting:
1) Used @L&LD 's guide to completely reset both my devices: https://www.snbforums.com/threads/major-issues-w-rt-ac86u.56342/page-4#post-495710
2) Used @OzarkEdge AiMesh Notes: https://www.snbforums.com/threads/o...-supported-products.44375/page-14#post-381537
3) I was on firmware 384.17
4) Returned the AC86U device and received another one thinking it was defective. Same problems after getting a replacement.
5) Tested both wireless bands on my AC68U for a few days independently (as a Media Bridge) and they were rock solid. I had thought that perhaps my AC68U was on its way out since I purchased it several years ago.
6) Tried upgrading to Asus stock version firmware published in May (86U: 384.81858; 68U: 385.20490). Still unstable despite notes of improved connection stability.
Result In the End / Conclusion:
1) I ended up downgrading to Merlin Firmware 384.13 (both routers) and I have not seen any issues for the past few days. I read another thread where someone was having a similar issue and used this as a last ditch effort before returning the router: https://www.snbforums.com/threads/deauthenticated-because-sending-station-is-leaving-ac68u.62451/ (thank you @Draken)
2) Kind of surprising and disappointing after serious trial and error. Hope this helps someone and Asus eventually gets this fixed. I surely cannot be an edge case of this happening to (or maybe I am). I also wonder if this happens for people who just have this particular configuration (1 AC86U Router; 1 AC68U AiMesh Node).
Setup:
AC86U = Main Router
AC68U = AiMesh Node
Backhaul = Wireless
Smart Connect = Disabled
SSID's = Same
AC68U = AiMesh Node
Backhaul = Wireless
Smart Connect = Disabled
