Not an adequate communications link between the outlet that the rcvr is plugged into and the Slinglink/Dishcomm to properly transmit the information that the rcvrs send out, or to fully access the functions of the rcvr remotely. You may be plugged into a surge protector, too far from the Slinglink or Dishcomm modem, missing a DSL filter on the line, plugged into a GFCI outlet, etc. We were told that all red confirmations would not count towards our connectivity when Dish pings the rcvrs. Satellite signal strength would have nothing to do with the actual send status as it is done through the high-speed internet or landline service.
