C5c problem lost conection

i have c5c lost conection many time in day i dont way

have you tried the new firmware? v2.8.0

Yes, and the problem was not solved. I need to know the reason for the interruptions

Looks like at least one of the reboots is from a loss of power.

Could be a bad PoE injector or Cabling or bad Ends. I would check those.

How gain of antenna are you using? There could be multiple issues here.
