Modem performance and modem selection.

Do you mean a cable modem like from Motorola, or do you mean a streamer??

If you mean a cable modem, not sure there’s any difference other than speed and reliability but I have two suggestions:

Use a cable TV isolator in front of the modem. This will prevent ground loops between your gear and the cable tv entrance.

Put all your networking/routing gear outside of your "clean power zone."


Use a separate power strip if necessary.

" use a cable tv isolator in front of the modem. this will prevent ground loops between your gear and the cable tv entrance "

you are suggesting the OP get something that he might not even need.

something like this could also cause issues with the return path.

Yes I did mean a cable modem.  Thank you for the responses.  However, with these responses being in conflict with each other...I am not sure which way to go.  I will keep the Cable modem outside of the clean power zone.  Thank you again.
