Frequently Asked Questions
Q. Can I run more than one device on the modem?
A. Yes. If your service provider permits, a single cable modem can support up to 63
Ethernet devices utilizing user-supplied Ethernet hubs or routers that you can
purchase at your local PC or office supply retailer. Another user at your location can
simultaneously connect to the USB port on the cable modem. Contact your service
provider for further assistance.
