@bubuyu @ladypxy https://help.ubnt.com/hc/en-us/articles/204909754-UniFi-Device-Adoption-Methods-for-Remote-UniFi-Controllers If you can SSH into the device, it's possible to do L3 adoption via CLI command: 1. Make sure the device is running updated firmware. 2. Make sure the device is in the factory default state. 4. After issuing the set-inform, the UniFi device will show up for adoption in the Devices section of the controller. Once you click Adopt, the device will appear to go offline or have the status of "Adopting". 总归是要重置的, 而且要求最新固件
