Hello @AMG_55,

The PMF feature was supported since Omada Controller v5.7, which requires to upgrade the EAP device firmware to take effect.

While the EAP655-Wall 1.2.2 and EAP650-Wall 1.1.2 are both adapted to controller 5.9, which supports the PMF feature. It seems that your IoT client is non-PMF-capable, so changing PMF from "Mandatory" to "Capable" can fix the issue. If your IoT still has connection issue with the "Capable" option, you may disable PMF for the IoT network.

Could you please also tell your controller version, your previous EAP device firmware with the build number?

Hi @BoboXX，

Go to Settings > Wireless Networks > WLAN > Advanced Settings, here you can see the PMF feature:

Hi @AMG_55，

its strange problem for example i have wifi thermostat and its connect to my 2.4ghz wifi with 100% signal but when i change the temp from my pc or mobile its delay or not response

for now i rollback to the old firmware and everything work great

May I ask which specific version of the old firmware for EAP655-Wall and EAP650-Wall?

Did these issues occur on all client devices or just on the 2.4G devices?
