@John1234 the manual adopting thing i did aswell. about 8 times with different firmwares. i will try the downgrading next.

i tried the 10min without power thing, didn't work. now one of my offsite ER605's wont adopt anymore too. so i dont know.

@John1234 i will try waiting sometime. "sadly" i already deployed 2 offsite routers and some aps that are also connected to the controller, so i am more or less limited to night times for testing....

Hello! I've got a ER7206, a switch and some APs all connected to an oc300, but today the router "disconnected" and i failed re-adopting. its just disconnected and done after 2 tries. resetting, new...

@Philbert yes you can change the IP of the Controller, my problem ist that the offsite devices cant report to the Controller anymore afterwards. at least without resetting and re-adopting.

hello, is it possible to change the controller inform url/ip after all the routers and aps are adopted? without resetting them? thanx
