|The correct way to connect is as follows:|
Highspeed Cable Modem >> Router >> Switch
If you connect the switch before the router then anything else plugged into the switch is wide open to intrusion from the internet.
To feed your TV separately from the internet on cable, you put a cable splitter in the line before the highspeed cable modem. One goes to the modem, the other to the TV.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
