I have an Arris SB8200 and installed the MoCA network. Before I got done installing the 2nd POE filter, the MoCAs all connected and began working.
Is the 2nd filter really necessary? How can I tell if there is an issue because the second filter is not there?
Will I need to have a filter between the inbound internet line and the HDHomeRun Prime cable device as well?
SB8200 is a DOCSIS 3.1 modem. The upper frequency can be up to 1218MHz. Will has overlap with MoCA(1125-1675MHz).
So you'd better to install the 2nd filter to separte the two netoworks.
If there is no such filter, there are maybe some packet loss or link unstable.
