Thanks @RMerlin !
I applied the 388_22068 firmware to my AX6000 and enabled AIProtection successfully without reboots now for 2 days!
(now if we could only get dual WAN failover/fallback to work better)
Anyone update and stable that has AiProtection enabled with 2.5Gb hardware connected? My GT-AX6000 with 2.5Gb modem and 2.5Gb switch connected to the 2.5Gb ports goes into reboot loop on .388.21617 with AiProtection enabled. If I disable AiProtection, works great. If I unplug 2.5Gb ports...
