    Are you getting any error messages ?
    If you connected the coax after you plugged in the H21 you can get a 775 error. To remedy this, unplug the unit and wait at least 1 minute and then plug it back in.

    You should use either a Band-Stop Filter or a DECA if you aren't already. These shield the H21 from the MoCA signals.

    You must NOT use a BBC.

    A BSF or Band Stop filter is used to block the DECA signal to receivers that don;t needed like all SD receivers as this signal is stronger than the satellite signal and in the long run it can damage the receivers.

    My money is on problems associated with not using a BSF. ;)
