Cannot connect to EAP225, green light for 4 seconds
Hello - if this is not in the right forum, sorry, my first post...
Just bought a new EAP225 ceiling mount (aka TP-Link AC1350) and I cannot connect to it. I have it connected to the POE switch, the small light on the POE adapter is on, the LED on the device shines green for about 4 seconds, goes off for a second, then back on for 4 seconds, and repeats. I am trying to use it as an access point for my TP-Link Archer C4000 router (which is working fine, by-the-way).
It displays the two SSIDs, one for 2.4 GHz and one for 5 GHz, but when I try to connect, the connection times out (my Android phone says it couldn't get an IP address).
Although it is wired to my C4000 router, I cannot see it in the router. Since I cannot connect to it, or see it from the router, I cannot enter to do any admin work (reset SSID, use internet, etc).
I have downloaded the Omada app, but it says it cannot see any controllers, and when I go to add the EAP225, the software asks me to scan the QR code (which doesn't exist on the device), or enter the "Device ID" which also doesn't exist on the label on the bottom of the EAP225.
I have done a reset (pressed the reset button) and the results are the same.
Anyone have a suggestion to get this working?
Thanks,
Bill
