How Do I Configure the Cable Modem 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:
Disabled (factory default)
802.1x
WPA
WPA-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 Pre-Shared Key Allows you to set a WPA Pre-Shared encryption 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 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.
WPA Group Rekey
Interval
Allows you to set the WPA Group Rekey Interval in
seconds. This only applies when WPA and WPA-
PSK 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.
