ePMP 2000 with smart antena this problem Smart Antenna is Disconnected, Power Off

I have the antenna mounted since 2016 I have updated the firmware to version 3.5.2 and it gives me the message in red this of the smart antenna (Smart Antenna Smart Antenna is Disconnected, Power Off) what can I do?

Hi,

Please try to reboot the AP.

It makes sense to check Smart Antenna cables too.

Thank you.
