Section Field Description  
Wireless Network Name (SSID) 
The SSID is the name of your wireless network. The SSID is used by wireless 
technology to identify your network from other wireless networks in the area. 
The SSID can be up to 32 characters long. The factory default SSID is typically 
the last 6 characters of the CM MAC address found on the rating label located 
on the bottom of your gateway. 
This SSID is a unique identity and does not need to be changed unless you 
choose to do so. Your service provider may provide you with wireless setup 
information that may call for a different SSID. 
BSSID 
Displays the Basic Service Set Identifier (BSSID) of your wireless network. The 
BSSID is typically the MAC Address of the wireless access point.  
Note: This may not be the same MAC Address as the CM MAC Address used 
to determine the factory default SSID. 
Broadcast SSID 
When this box is checked (factory default), the gateway transmits or advertises 
its presence to other wireless devices. Client devices can automatically detect 
the access point when this beacon is enabled. 
Uncheck this box if you want to hide your network from wireless clients. If you 
hide your network, you will need to configure each of your wireless client 
devices manually. 
Important: The Enable check box is not currently in use and does not impact 
operation of the gateway.  
Wireless > Wireless Security 
Selecting a wireless security mode helps protect your network. If you select Disable, 
then your wireless network is not secure and any wireless device within range may 
connect to it.   
To keep intruders out of your wireless network, use the Wireless Security page to 
configure your security parameters including the security mode (the level of 
encryption), encryption keys, and other security settings. 
Select the Wireless Security tab to open the Wireless Security page. The following

Security 
Wireless Security Mode 
Choose one of these options for the security mode: 
WEP 
Wired Equivalent Privacy (WEP) security mode is defined in the original IEEE 802.11 standard. 
This mode is no longer recommended because of its weak security protection. Users are urged to 
migrate to either WPA-Personal or WPA2-Personal. 
Note: WPS mode does not support WEP on this device. 
 
Field Descriptions 
 Encryption. Select a level of WEP encryption, 40 / 64 bits (10 hex digits) or 104 / 128 bits (26 
hex digits). 
 Wireless Passphrase. To complete your wireless security setup, you should choose a wireless 
passphrase that is easy for you to remember and hard for anyone else to guess. The first time 
you connect a new wireless device to this network you may need to enter this passphrase into 
the appropriate setup section in the connected device. To improve your network security, do 
not give out this passphrase to unauthorized uses. Please enter a phrase of letters and/or 
numbers from 4 to 24 digits long. Then, click Generate to create the Passphrase. 
 Key 1-4. If you want to manually enter WEP keys, then complete the fields provided. Each 
WEP key can consist of the letters A through F and the numbers 0 through 9. It should be 10 
characters in length for 40/64-bit encryption or 26 characters in length for 104/128-bit 
encryption. 
 TX Key. Choose a Transmit (TX) Key from 1 to 4. The TX key is the key that will be used to 
encrypt your data. Although four keys can be created, only one key is used for encrypting 
data. Select one of the four keys for WEP encryption. Use the selected TX key to set up your 
wireless clients.

Section Field Description   
 WPA 
Security for Personal Networks – WPA or WPA2 Personal Modes 
Wi-Fi Protected Access (WPA) is a more secure wireless technology than WEP. WPA can be used 
for both Enterprise (corporate applications) and Personal (home network) wireless networks. We 
strongly recommend that you select either WPA-Personal or WPA2-Personal as the security mode 
for your home network, depending on which mode is supported by the wireless adapter in your 
PC or wireless clients. 
WPA-Personal (aka WPA-PSK or WPA-Pre-Shared Key), provides a more secure wireless 
network that WEP. WPA-Personal introduces TKIP user authentication and stronger encryption 
keys than WEP. 
WPA2-Personal (aka WPA2-PSK or WPA2-Pre-Shared Key) provides the most secure standards-
based wireless networking. WPA2-Personal incorporates AES (Advanced Encryption Standard) 
for data transmission. 
Note: Not all wireless adapters support WPA2. WPA is supported across a wider range of 
devices. Whether you use WPA or WPA2, make sure to use a ―strong‖ passphrase. A strong 
passphrase is a string of random characters at least 21 characters in length.  
Select from one of the following three WPA or WPA2 Personal modes: 
 WPA-Personal 
 WPA2-Personal 
 WPA or WPA2-Personal 
 
Field Descriptions 
 Encryption. The default is TKIP+AES. 
 Pre-Shared Key. Enter a key of 8 to 63 characters. 
 Key Renewal. Enter a Key Renewal period, which instructs the device how often it should 
change encryption keys. The default is 3600 seconds.
