I received the switch in the link I provided above, but I'm still very confused. There is no "Main" plug in from the cable modem. Just 5 ethernet plug-ins. The instructions, what very tiny amount there is, only says to plug an ethernet cat6(which I also purchased) cable from a computer, into the switch. What am I missing here? The switch still needs internet from the modem, right? Do I just plug in the ethernet cable from the modem into one of the switch plug-ins as well?
