@ghost124 Have you tried to adopt it connected to a different source?  Is it getting power?  Did you try different ports on the router?

Hi  @ghost124 

If the Omada devices are showing as "pending" on the controller but fail to be adopted, you can follow these steps to troubleshoot the issue:
1. Pay attention to any error messages that appear when you click the "Adopt" button. Here are some common errors and their solutions:
    a) "The Username or Password is incorrect": Check if the default username/password of the Omada device (usually admin/admin) has been changed. If you have forgotten the credentials, you can reset the device by pressing the reset button.
    b) "Device adoption failed because the device does not respond to adopt commands": This error indicates a communication issue between the EAP (Omada device) and the Omada Software Controller/Hardware Controller. Ensure that TCP/UDP ports 29810-29814 are open in any antivirus or firewall settings.
2. Update the firmware of the devices.
3. Try to reset the device and restart the controller.

Thank u for ur response,

I tried with ping and the communication between the software controller and the device is succeed. 

The problem is when i click adopt, it's moving from PENDING>ADOPTING>PROVISIONING then everything is destroyed (the internet cutting off, both WIFI of the EAP610 does not appears in the PC). So every time I do reset the devise nd reconfigure it from the begging.

Like it shown in the captures

I hope it's clear

thank you.

  @Vincent-TP Thanks, the problème was solved nd the devise connected to the manager, but the wifi doesn't appear in the wifi list.

Thank u again
