Yes, i am having same issues also running on Merlin 386.1.2 with setup of RT-AC86U as main router and RT-AC68U as AIMesh Node. Seeing from the log, the AIMesh Node will disconnect a few times in a day and this is happening every day so i am not sure what is causing this. Kindly report back your findings and if 386.2 still can't resolve this issue, i have to roll back to 384.19 for the stability.
