You don't normally connect a MOCA bridge directly to your router. You connect a MOCA bridge to your coax where you need an ethernet connection.
said by andyboy:Is there a limit to the number of devices I can connect with this method?
Not clear whether you're referring to MOCA devices or ethernet devices. There is no limit to the number of ethernet devices you can connect. The number of MOCA devices depends on the version of your MOCA devices. The limit is 8 for MOCA 1.0. This includes the router, MOCA bridges, and STBs. The limit is 16 if all devices are MOCA 1.1 compliant. If you have a mix of MOCA 1.0 and MOCA 1.1 devices, the limit is 8.
said by andyboy:I assume I can connect just one bridge to my router
There is no need to connect a MOCA bridge to the router. The router has a built-in MOCA bridge.
said by andyboy:I am not sure what the channels mean when it comes to MOCA.
A channel is simply a frequency over which MOCA data is transmitted.
said by andyboy:If I connect 4 other devices throughout the house via MOCA bridges, I assume they would all work because they would be on the same channel, correct?
Yes, assuming you're not exceeding the MOCA device limits.
