Introduction
Thank you for purchasing the
Samsung InfoRanger™ Cable Modem
1. What is the Samsung InfoRanger™ Cable Modem?
Simple and smart, the InfoRanger™ is a true cable modem (MOdulator -
DEModulator) that connects your PC or Ethernet LAN to the Internet and
other multimedia services and networks through your cable TV network.
The InfoRanger™ not only frees up your telephone lines, but gives you
unprecedented transmission speeds for accessing the Internet and the World
Wide Web, interactive communications, e-mail, file transfers and data down-
loads and uploads.
Depending on your cable service’s performance, the InfoRanger™ will pro-
vide downstream (receiving) data speeds up to 100 times faster than the
fastest dial-up (telephone) modem, and upstream (sending) speeds up to 100
times faster than dial-up modems.
The Samsung InfoRanger™ Cable Modem puts you at the leading edge of PC-
connectivity technology.
With this device, you’ll be entering a new dimension of PC and PC-network
capabilities and productivity through a quantum leap in the speed of accessing
the Internet and other multimedia resources via your local cable TV network.
2. Connectivity/Adaptability: the DOCSIS-compliant InfoRanger™.
The Samsung InfoRanger™ complies with DOCSIS (Data Over Cable Service
Interface Specification).
This assures you that your InfoRanger™ will operate with the connectivity
technology of all cable TV service providers and will be compatible with other
brands of cable modems.

modem from the PC.
When this display switch is off, the modem is still powered, interfaced to the
cable, and is on standby.
The modem in this state can send to, and receive data from, the head-end, but
cannot communicate with the PC through the Ethernet port.
In this state, the LEDs are off. There is no indication of modem operation.

If you do not have an Ethernet interface, you will need to call your CATV
provider.
If you do have an interface, then call your CATV provider for TCP/ IP configu-
ration settings, such as DHCP settings, domain name, host name, DNS ser-
vice search order, primary WINS server IP address and secondary WINS
server IP address.
