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

table shows examples of the Wireless Security page with various wireless security

modes selected.

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.

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.
