1. Before You Begin
Your new wireless cable modem provides high-speed wireless access to the Internet by using
IEEE 802.11b wireless standard and an active Internet Connection through your cable
service provider. This user guide describes how to set up and use the wireless cable modem.
Before installing the wireless cable modem, you should read this user guide to ensure proper
wireless cable modem operation.
Understand the Wireless Cable Modem’s Features
Your wireless cable modem has the following features to help you access and use the Internet:
• Wireless connectivity means that you can use your PC just about anywhere in your
home.
• 802.11b compliance ensures interoperability with other 802.11b compliant devices
• Your wireless cable modem supports transmission rates of 11, 5.5, 2, and 1 Mbps. If
the signal becomes weak, your wireless cable modem will automatically fall back to
the optimal transmission rate.
• Two-way design allows the wireless cable modem to send and receive data over the
cable television network.
• Cable bandwidth allows data rates of up to 38 megabits per second (Mbps)*, which is
faster than analog modems, integrated services digital network (ISDN), or asymmetric
digital subscriber line (ADSL).
• Using your cable line means that the wireless cable modem is always on, always
connected, and doesn’t tie up your phone line.
• Plug-and-play operation through universal serial bus (USB) ensures easy setup and
installation.
• Data Over Cable Service Interface Specification (DOCSIS) compliance ensures
interoperability with DOCSIS compliant cable operators.
*NOTE: Speeds may vary based on the following factors:
• Computer equipment including available RAM and processor speed
• Software applications utilizing your computer’s resources
• Network traffic depending on the time of day
• Limitations set by your Cable Service Provider

NAT
Network Address Translation/Port Address Translation (NAT/PAT) gateway is designed for IP
address simplification and conservation, as it enables private IP network that uses no registered IP
addresses to connect to the Internet. NAT/PAT operates on a wireless LAN cable modem,
connecting to Internet, and translates the private (not globally unique) addresses in the internal
network into legal addresses before packets are forwarded onto the Internet. As part of this
functionality, NAT can be configured to advertise only one address for the entire network to the
outside world. This provides additional security, effectively hiding the entire internal network
from the world behind that address. NAT has the dual functionality of security and address
conservation, and is typically implemented in remote access environments.

Wireless LAN Cable Router IP address. The standard MAC access list performs frame filtering
based on source MAC address from the CPE host(s). Basically, the access list works as a source
address packet filter, if the access list is empty, the cable router will forward any packet, if access
list is not empty, packet filtering will be enforced according to the access list(s). The wireless MAC
access list performs filtering based on source MAC address from the wireless card, configure this
list will make only the wireless card’s MAC address match this list will be associate to wireless AP.
1~20, access list ID, for standard IP access list
21~40, access list ID, for management access list
41~60, access list ID, for standard MAC access list
61~75, access list ID, for Wireless MAC access list
Example:
1) Set the access list to permit source IP 192.168.100.xxx to access network.
CM>access-list 1 permit 192.168.100.1 0.0.0.255
Note: 0.0.0.255 means 192.168.100.1~192.168.100.255
2) Set the access list to permit source IP 192.168.100.10 to access cable router (telnet, web-page,
snmp)
CM>access-list 21 permit 192.168.100.10 0.0.0.0
Note: No network packet will be filtered
3) Set the access list to permit source MAC 00D0.5921.3354 to access network
CM>access-list 41 permit 00d0.5921.3354 ffff.ffff.ffff
Note: The cable router only forward packet with this source MAC, all other packet will be
discarded.
4) Set the access list to permit source MAC 00D0.5911.22.33 to associated the wireless Cable
Router
CM>access-list 61 permit 00d0.5911.2233
¾ access-list delete {list ID|all}

Wireless Configuration
SSID
• You can input SSID to group your wireless network. The wireless clients that have the
same SSID can communicate with others.
Host
• In Host item, you can define the wireless cable modem name.
Channel
• There are 11 channels available for US. You also can specific wireless
communication channel in Channel section. If there are multiple wireless cable
modems or access points in the same area, wireless channels should be well organized
to avoid interference. We recommended the adjacent wireless cable modems or
access points should be 5 channels apart. For example, WLCM1 is channel 1, then the
next cell, WLCM2 should use channel 6.
Security WEP
• Security WEP (Wired Equivalent Privacy) offers wireless data security. The default
WEP setting is “off”. You can enable this function by choosing two types of WEP
keys, 64 or 128 bits.

WEP Key
• 64 bits WEP requires a 10 Hexadecimal digits key, and 128 bits WEP key needs a 26
Hexadecimal digits key.
Access Permission
• Access permission is set for “Allow everyone access” by default.
• If Access Permission is set for “only allow access if on this list”, only CPE with
matching MAC address from the list is allowed to access.
