There are at least two ways. First, you connect the wireless router directly to the cable modem, and then the switch in the wireless router. You have to connect the cable coming from the modem in the wireless router internet port. Second, you connect the wireless router to the switch, again the cable coming from the switch you have to connect on the wireless router internet port. It's better to put the wireless router just after the modem, but it's not required.
