1. PRODUCT OVERVIEW
The wireless cable modem is a DOCSIS compliant wireless cable router
that provides high-speed connectivity to residential, commercial, and
education subscribers on public and private networks via an existing cable
infrastructure. The wireless cable modem is equipped with IEEE802.11b
wireless AP, and can inter-operate with the Wi-Fi compliant IEEE 802.11b
wireless LAN card. The wireless cable modem can inter-operate any
DOCSIS compliant headend equipment. The IP traffic can transfer between
the wireless cable modem and DOCSIS compliant headend equipment. The
data security secures upstream and downstream communications.

2.2 Installation Procedure
This cable modem equips USB and Ethernet interfaces. You can choose
either one to connect to the cable modem. Go to Section 2.2.1, if your
computer has installed TCP/IP and Ethernet card with 10/100BaseT
capability. Go to Section 2.2.2, if your PC has USB port and the operating
system is Microsoft Windows 98/Me or Windows 2000/XP.
2.2.1 Installation Procedure for Ethernet Interface
Follow the following instructions for proper installation:
Step 1:Make sure your computer meets the system requirements in Section
1.2.
Step 2:Connect a coaxial cable (supplied by the local Cable Television
Company) to the CABLE connector on the modem.
NOTE: To speed up the initial cable modem registration process, the coaxial
cable should be connected to the modem prior to the power
connector.
Step 3:Connect the RJ45 Ethernet cable to the ETHERNET connector on the
modem, connect the other end with the 10/100BaseT Ethernet port
on your computer.
Step 4: Plug the power adapter into the POWER connector of the modem.
Step 5: Plug the other end of the power adapter into a power outlet.
