Switched to Beta 2 this morning. Really amazing stability and speeds on my 3 node RT-AC68U Mesh setup.
1 node was never used in the past, even though it was closer to some clients.
Distribution between nodes is much faster and feels more optimized.
Looking forward to the final release ;)...
Also pretty stable for me. The main router (AC68u) has been running stable for 13 Days :)
I had some random reboots of two AIMesh Nodes (same model) in the past days, but they reconnected without a reboot.
