This cable modem equips USB, wireless and Ethernet interfaces. You can choose either one to connect to the cable
modem. Go to the “Installation Procedure for Ethernet Interface” section, if your computer has installed TCP/IP and
Ethernet card with 10/100BaseT capability. Go to the section “Installation Procedure for USB Interface”, if your PC
has USB port and the operating system is Microsoft Windows 98/ME/XP or Windows 2000.
Note: You don’t need to do installation for wireless interface.
Installation Procedure for Ethernet Interface
Follow the steps below for proper installation:
1. Connect a coaxial cable (supplied by the local Cable Television Company) to the CABLE connector on the
modem.
Note: To speed up the registration process of cable modem, the coaxial cable should be
connected to the modem prior to the power connector.
2. Connect the RJ-45 Ethernet cable to one of the ETHERNET connector on the modem, connect the other end
with the 10/100BaseT Ethernet port on your computer.
3. Plug the power adapter into the POWER connector of the modem.
4. Plug the other end of the power adapter into a power outlet.
5. The cable modem will look for the proper cable modem signal in the Cable Television network and process the
initial registration. The cable modem is ready for data transfer after the LED “CABLE” is in solid green.
Note: The Reset button at the rear panel is for maintenance purpose only.

Wall Mounting
The number of the screw: 2 pcs
Direction for wall mounting: LED panel upward.
Dimension for the screw: TBD
There are 2 slots on the underside of the Cable Modem and 4 slots on the underside of the Battery Pack that can be
used for wall mounting.
Note: When wall mounting the unit, ensure that it is within reach of the power outlet.
You will need 2 suitable screws which screw diameter would be 4.4 mm to wall mount the Cable Modem or the
Battery Pack. Two different wall mount directions could be chosen for the Battery Pack.
To do this:
1. For the Cable Modem, ensure that the wall you use is smooth, flat, dry and sturdy and use the 2 screws holes
which both are 101.6 mm apart.
2. For the Battery Pack, ensure that the wall you use is smooth, flat, dry and sturdy and use the 2 screws holes
which both are 101.6 mm or 152.0 mm apart for two different mount directions.
3. Fix the screws into wall, leaving their heads 3 mm (0.12 inch) clear of the wall surface.
4. Remove any connections to the unit and locate it over the screw heads. When in line, gently push the unit on
to the wall and move it downwards to secure.

For this mode, the settings that you can adjust
including wireless encryption level, default key,
passphrase for keys, wireless wep key #1 to #4.
Wireless Encryption Level:
Select the WEP mode for the WEP key function. You
can choose 64-bit or 128-bit for your necessity. If
you choose Off, the Encryption Keys will not be
shown on this page. If selected, data is encrypted
using the key before being transmitted. For example,
if you set 128-bit in this field, then the receiving
station must be set to use 128 Bit Encryption, and
have the same Key value too. Otherwise, it will not
be able to decrypt the data.
Default Key:
Select one of network key (from 1 to 4) that you set
on the Key boxes as default one.
PassPhrase for Keys:
You can type in ASCII codes into this field. The
range is from 8 characters to 64 characters. For
ASCII characters, you can type in 63 characters
in this field. If you want to type in 64 characters,
only hexadecimal characters can be used.
Generate WEP Keys:
Click this button to generate the PassPhrase.
Wireless WEP Key #1 to #4:
Type the encryption key length and fill out WEP
keys. The system allows you to type in 4 kinds of the
WEP key. For 64-bit WEP mode, the number you
can type is that 5 characters or 10 hexadecimal digits.
As for 128-bit WEP mode, the number you can type
is that 13 characters or 26 hexadecimal digits.

For this mode, the settings that you can adjust
including RADIUS Server, RADIUS Port, and
RADIUS Key.
RADIUS Server Address: RADIUS Server is a
protocol for carrying authentication, authorization,
and configuration information between a Network
Access Server which desires to authenticate its links
and a shared Authentication Server. Please type in the
IP Address for the RADIUS Server.
RADIUS Port: Except for the IP address of the
RADIUS Server, you have to enter the port number
for the server. Port 1812 is the reserved
RADIUS-authentication port described in RFC 2138.
Earlier AP (RADIUS clients) use port 1945. The
default value will be shown on this box. You can
keep and use it.
Shared Key: A Shared Key is like a password,
which is used between IAS and the specific RADIUS
client to verify identity. Both IAS and the RADIUS
client must be use the same Shared for successful
communication to occur. Type in the words for the
Shared Key.
After finished settings, click Save Settings for

For the WPA network Authentication, the settings
that you can adjust including WPA Algorithms,
RADIUS Server Address, RADIUS Port, Shared key,
Key Renewal Timeout.
WPA Algorithms: Select the data encryption for the
WPA mode. There are two types that you can choose,
TKIP and AES.
RADIUS Server Address: RADIUS Server is a
protocol for carrying authentication, authorization,
and configuration information between a Network
Access Server which desires to authenticate its links
and a shared Authentication Server. Please type in the
IP Address for the RADIUS Server.
RADIUS Port: Except for the IP address of the
RADIUS Server, you have to enter the port number
for the server. Port 1812 is the reserved
RADIUS-authentication port described in RFC 2138.
Earlier RADIUS clients use port 1945. The default
value will be shown on this box. You can keep and

Shared Key: A Shared Key is like a password,
which is used between IAS and the specific RADIUS
client to verify identity. Both IAS and the RADIUS
client must be use the same Shared for successful
communication to occur. Type in the words for the
Shared Key.
Key Renewal Timeout: Type in the time for the
WAP group rekey interval. The unit is second.
TKIP takes the original master key only as a
starting point and derives its encryption keys
mathematically from this mater key. Then it
regularly changes and rotates the encryption keys
so that the same encryption key will be never used
twice.
AES provides security between client
workstations operating in ad hoc mode. It uses a
mathematical ciphering algorithm that employs
variable key sizes of 128, 192 or 256 bits.
After finished settings, click Save Settings for

If the suggested solutions in this section do not resolve your issue, contact your system administrator or Internet
service provider.
Can I use the same cable line for TV and cable modem?
A. Yes, the TV and cable modem uses the cable line. You need a splitter to use them at the same time. Ask Cable
Company to install the splitter for you to avoid signal degradation.
My cable modem cannot get a solid green light on the Status LED when I connect
the cable back.
A. The cable modem lost the signal during the disconnection period and it will keeps scanning other available signal.
When you connect the cable back, it might take a while to find the correct channel. You can power cycle the
modem to speedup the process since modem will remember the channel last time and it will start from that
channel at startup.
Which port of the Ethernet hub should I connect to the modem if I need to connect
multiple PC to the modem?
A. You should connect the modem to the up-link port of the hub. The link LED of the hub will be on.
How do I see my IP address?
A. If you are using Windows 95/98/ME, the winipcfg command will show you to IP address of the PC connected to
the cable modem. Notice that even though you seem get the same address all the time, it may still be a dynamic
address.
Can I just connect the cable modem and two computers to a hub?
A. Yes. You need to make sure you can get two IP addresses from your cable modem service provider. Connect the
modem to the up-link port of the hub.
I have a cable modem. How can I make it work?
A. Basically, modem is plug and play. You can just connect the modem and you are ready to go if you have the
subscription. For ensure good signal for your cable modem, you should ask your cable provider to install the
cable modem for you.
Can I switch between a notebook and PC using the same cable modem? Will there
be a problem to obtain a DHCP IP address?
A. This issue depends on how your cable modem service provider manages the modems. If you are using one of the
cable modem service providers that register your PC based on the MAC address of the Ethernet card in the PC,
then you will have to call them and have them change that entry every time you switch between the two. Ask
them if you have problem on this issue.
