Cabling for Multiple Users
The SURFboard cable modem supports several multiple user configurations. Along with
an optional hub or router, it can serve as an Internet gateway for up to 32 computers.
For information about multiple user service, contact your cable service provider.
Ethernet and USB
You can connect the USB port on one computer and the Ethernet port on another
computer directly to the cable modem, as shown at top left.
Caution
You can connect a single computer to the USB port and from one to 31 remaining users
to an Ethernet hub, as shown at bottom left. You cannot connect more than one
computer to the cable modem through the USB port.
Do not connect both the Ethernet and USB cables to the same computer.
