WebSTAR DPC2223 and EPC2223 VoIP Cable Modem User’s Guide Preliminary Draft 02 – 1/26/06

Q. After my cable modem is connected, how do I access the Internet?
A. Your local cable service provider becomes your Internet Service Provider
(ISP). They offer a wide range of services including e-mail, chat, news, and
information services. Your cable service provider will provide the software you
will need.
Q. Can I watch TV and surf the Internet at the same time?
A. Absolutely! If you subscribe to cable television service, you can watch TV and
use your cable modem at the same time by connecting your TV and your cable
modem to the cable network using an optional cable signal splitter.
Q. Can I run more than one device on the modem?
A. Yes—a single WebSTAR cable modem will theoretically support up to 253
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
cable service provider for further assistance.
Common Troubleshooting Issues
I don’t understand the front panel status indicators.
See Front Panel LED Status Indicator Functions, later in this guide, for more
detailed information on front panel LED status indicator operation and function.
The modem does not register an Ethernet connection.
• Verify that your computer has a 10/100BaseT Ethernet card and that the
Ethernet driver software is properly installed. If you purchase and install an
Ethernet card, follow the installation instructions very carefully.
• Verify the status of the front panel status indicator lights.
The modem does not register an Ethernet connection after connecting to a hub.
If you are connecting multiple PCs to the cable modem, you should first connect
the modem to the up-link port of the hub. The LINK LED of the hub will illuminate
continuously.
The modem does not register a cable connection.
• The modem works with a standard 75-ohm RF coaxial cable. If you are using
a different cable, your cable modem will not function properly. Contact your
cable service provider to determine whether you are using the correct cable.
• Verify that you have followed the procedures in Troubleshooting My
Internet Service Installation, earlier in this guide.
• Your NIC card or USB interface may be malfunctioning. Refer to the
troubleshooting information in the NIC or USB documentation provided with
the device.
