Hello , Little test of latest beta from 386.7_2.
I have 2xAX86U, with 388.1 Beta 2 , I have little issue with mesh , connection is ok but on WebGUI I have "great" connection but with red alert.
I can't manage my mesh node with this issue (test with led on/off for example). I rollback to previous and all is ok now.
I will retry when RC or final. Thank you for your amazing work.
I have almost the same setup, only a Ax86s as node. In my experience running the latest Merlin beta on the router and latest stock on the node (both 388) gives the best stability. You can give it a try if you want.
