This is correct.

You need one IP for each device attached to the modem, and the modem itself can only issue ONE IP.

Your simplest option is to get rid of the switch, and get a router.

Basically, a router issues it's own IPs (usually in the range 192.168.1.2 to 192.168.1.254) to any PCs/Printers/Xboxs attached to it, and uses the IP from the modem for itself. It then manages traffic between your home network and the modem (this is called Network Address Translation) and essentially makes your network appear to be one device.

Switches cannot do this.
