How Do I Configure My DOCSIS Residential Gateway?
Field Name
Description
Network
Authentication
Network Authentication allows only authorized users to
gain access to your wireless network. Only users with an
authorized user name, password, or pre-shared key are
allowed access to the wireless network.
Select from the following Network Authentication
protocols:
±
Primary Network
±
WPA
±
WPA-PSK
±
WPA2
±
WPA2-PSK
Note:
Network Authentication restricts access to your
wireless network to only authorized computers or users.
Authentication does not protect the data you send over
the wireless network connection. You must enable
encryption to protect data that is transmitted over your
wireless network.
WPA/WPA2
Encryption
Allows you to select a WPA/WPA2 security method. The
factory default security is WPA-PSK.
±
TKIP (Temporal Key Integrity Protocol) data
encryption is automatically enabled when WPA and
WPA-PSK network authentication is enabled. (factory
default)
±
AES (Advanced Encryption Standard)
±
TKIP-AES
Note:
Select TKIP-AES only if your client adapter
supports this mode. Contact your service provider for
assistance.

How Do I Configure My DOCSIS Residential Gateway?
Field Name
Description
WPA Pre-Shared Key
Allows you to set a WPA Pre-Shared key. Enter a text
string in this field. The text string or phrase is used to
generate a unique set of encryption keys for your
network. Use this string to set up wireless devices in your
network.
The factory default security key is the 9-digit serial
number of the gateway. For example: 20167792. See How
Do I Set Up My High-Speed Internet Access Account? for
the location of the serial number on the label.
±
The PSK can be either a text string or a 64 character
hexadecimal number.
±
The text string must be an ASCII character string with
a minimum of 8 characters but no more than 63.
Note:
Not all wireless adapter devices support PSK. For
these devices, you must enter the encryption keys exactly
as they appear in the in wireless gateway fields in the
preceding illustration of the Setup Wireless Security page.
RADIUS Server
Allows you to enter the IP address of the RADIUS server
used for authentication and encryption key derivation.
±
This field is used with 802.1x and WPA Network
Authentication.
±
The factory default for this field is 0.0.0.0.
RADIUS Port
Determines the port number of the RADIUS server. The
port number is usually 1812 (factory default) or 1645,
depending on the server used.
This field is used with 802.1x and WPA Network
Authentication.
RADIUS Key
Allows you to set the Shared Secret key for your RADIUS
connection.
±
The factory default for this field is empty.
±
This field is used with 802.1x and WPA Network
Authentication.
Group Key Rotation
Interval
Allows you to set the WPA Group Key Rotation Interval
in seconds. This only applies when WPA or WPA2
Network Authentication is enabled.
Set this value to 0 (factory default) to disable periodic
rekeying. The valid range is 1 to 4,294,967,295 seconds.

Description
WPA/WPA2 Re-auth
Interval
Allows you to set the WPA/WPA2 Re-authorization
Interval in seconds. This only applies when WPA/WPA2
Network Authentication is enabled.
Set this value to 0 (factory default) to disable periodic
rekeying. The valid range is 1 to 4,294,967,295 seconds.
WEP Encryption
Allows you to enable data encryption to help secure the
data that is sent over your wireless network.
WEP 128-bit
±
128-bit or-64 bit static key data encryption can be
selected when the network is configured to have no
authentication.
±
128-bit static key data encryption is automatically
selected when 802.1x network authentication is
enabled.
Notes:
±
Static key authentication uses one of the four
encryption keys, as defined below, to encrypt your
data. You must manually change keys. The keys do
not change or rotate automatically as they do with
TKIP.
±
64-bit and 40-bit encryption are two different names
for the same encryption
±
128-bit and 104-bit encryption are two different
names for the same encryption
Shared Key
Authentication
Allows you to determine is Shared Key Authentication is
used in the network. Shared Key Authentication can be
used when there is no other network authentication in the
network.
±
Optional - (factory default)
Wireless clients can associate with the wireless access
point without authentication.
±
Required - Only wireless clients with a valid network
key are allowed to associate with the access point.
802.1x Authentication
Allows you to use 802.1x authentication with WEP
encryption (similar to when WPA or WPA2 is enabled)

Description
Network Keys
1 through 4
64 bit keys
or
Select these keys for use with Encryption Mode set to 64-
bit encryption. Enter 5-byte values for a Key. You do not
have to set all four Keys. Only one Key is used for a home
network. Each value is represented in hexadecimal. Use
only these numbers or letters: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b,
c, d, e, and f to set up your encryption keys.
Note:
It is generally a good practice to use only lowercase
letters when entering WEP encryption keys. Uppercase
letters can sometimes be confused with numbers. For
example, the uppercase letter “B” is often mistaken for the
number “8.” Using lowercase characters minimizes the
risk of confusing characters when copying keys from one
device to another. Uppercase characters will
automatically be converted to lowercase when the key or
keys are applied and saved to memory.
Use two numbers or letters in each box. Record your Key
values. You will need these Key values when you set up
your client wireless adapter. The Key values in each
wireless network device must match.

Field Name
Description
Current Network Key
Allows you to select which of the four 64-bit or 128-bit
keys to use to encrypt your data when you are using
encryption that requires the manual entry of an
encryption key. Only one WEP key is in use at a time. You
must manually change keys. They do not change
automatically.
Notes:
±
64-bit and 40-bit encryption are two different names
for the same encryption
±
128-bit and 104-bit encryption are two different
names for the same encryption
PassPhrase
Automatically generates WEP encryption keys required
to communicate with the network.
Although not required for WEP operation, use of a
PassPhrase can simplify the configuration and setup of
each of your client wireless adapters.
Using a PassPhrase eliminates the need to manual enter
lengthy encryption keys and reduces the chance of error
associated with entering entry of large numbers.
