Just to inform you so if someone have a similar setup and problem.
I have 3 AC66U_b1 (2 aimesh)
I upgraded to 386.1_2 about ago and I add many instability problem. Even with a default reset I had Internet disconnecting from the provider, high memory usage (384 was about 25% and 386 was higher than 50%, sometime 90%), voip disconnecting. I probably rebooted 20+ times
I rolled back to 384.19 2 days ago and no more problem.
