@Rick115 CPE needs to be powered by Passive POE. Is there an incompatible issue with the switch here? Does your switch only support standard POE？

@gdurniak Maybe a request post you can put in here. You can also do the ping test, ping -t and keep the device running to observe the connectivity.

@sophiatailor Hi, setting the VLAN to establish the network separation. Check this for more info. Additionally, another easy way is to set the Guest network to separate the main LAN and the guest LAN.

@steveharington5 It would be better if they can provide more flexible space for us to operate.

@Fred_Handoko Uhm.......The error message I thought is a little reasonable, maybe you can backup the settings file and uninstall the controller for testing.

@GoodOmens Hey, it should be OK, the EAP655-Wall(US)_V1_1.0.2 Build 20221115 is the latest firmware on the US official website. You can subscribe this post for further updates.
