@Fae or somebody from TP-Link how to configure SHA2 encryption on ER605 v2 , and ER605 v1? next firmware have come on ER605 v1 but I don't find SHA2 on it either.

@FlashWeave Strange!! And your controller ip is 192.168.0.101?

@FlashWeave Ok, and you still have problem with adoption?

@dpl73 another option is Controller Migration, I have not tested this myself I always use backup and restore and it always work, but I think Controller Migration have option to set ip on new...

@dpl73 if everything is on same LAN do restore to new controller and then power off oc200, then device will then automatic find the new controller and adopt automatic. you dont ned to do anything,...

@HellBent Why not route to a Black hole, (an ip that not in use on your LAN) you can use same nex hop ip to all routing.
