@flabbybuns Is the light of the WAN ports still on? Have you changed different cables to test? Based on your description, it seems like the hard connection has some trouble.

@Daggett So is it working now?

@Oscar71 Is the main LAN wired connection working? Can a reboot of EAP or controller fix it? Did you set the management VLAN?

@HiBou30 Hi, ~60dbm means the signal strength is still good and reliable. EAP225 supports Mesh with the controller, change the channel and channel width for testing. Check this: How to Configure Load...

@Selwynas Hi, did you test with different clients, like your phone, iPad, or PC? It may be due to the connection machinist of client devices.

@Daire88 It definitely only supports 2.4G single band.
