Ruckus Metro Broadband Gateway
USM-Metro-RKS1-091807-01
Customizing Metro WLAN or Home WLAN Settings
•
Key Entry Method
•
Hexadecimal: The encryption key only accepts hexadecimal characters (0-9, A-F).
•
ASCII Text: The encryption key accepts ASCII printable characters.
•
Passphrase
: This assists in automatic key generation. Enter some text and click the Generate
button. The system will generate the WEP key automatically. You may specify a passphrase up
to 32 characters. Please note that the algorithm used for key generation may vary from system to
system. Checking the WEP keys used between wireless stations and the Metro Broadband
Gateway is recommended.
•
WEP Key
: Enter the key manually according to the Key Entry Method and Encryption Strength
settings.
•
Key Index
: Choose the index, from “1” to “4”, that the WEP key is to be stored in.

Customizing WPA Encryption
When WPA-Auto is selected, the wireless client decides the version of WPA will be used.
•
WPA
is the recommended default compatibility-wise. Wi-Fi WPA-capable PDAs and other
gadgets are usually limited to
WPA + TKIP
.
•
WPA2
is an advanced option.
WPA2
support on Windows requires a Microsoft patch and is only
available on Windows XP with Service pack 2 or later.
•
WPA-Auto
is an advanced option. Only the best WPA 802.11i-conforming/Wi-Fi WPA-certified
client devices can operate in this mode.
Use of WPA PSK allows automatic key generation based on a single passphrase. WPA-PSK provides very
strong security, but may not be supported on older wireless devices. In some cases, the older devices can be
upgraded with adapters to take advantage of WPA-PSK.
If you configure the Metro Broadband Gateway with WPA-PSK, some devices will not be able to connect
to your WLAN unless the devices are manually set to WPA-PSK and configured with the same passphrase.
To configure WLAN-specific WPA encryption settings, follow these steps:
1.
Open the Web User interface, and click
Wireless
under Configuration.
2.
When the Configure :: Wireless :: Common workspace appears, click the
Metro WLAN
tab.
3.
When the workspace appears, open the
Encryption Method
menu and choose
WPA
. An additional set of
WPA-specific encryption options appear in this workspace.
ALERT
Do not undertake the customizing of these options unless you are an experienced
network administrator or are under the guidance of an IT/support professional.

You can make the following changes:
•
WPA Version
: Your options are WPA, WPA2 or WPA Auto.
•
When WPA-Auto is selected, the wireless client decides the version of WPA will be used. WPA
is the recommended default for best compatibility. Wi-Fi WPA-capable PDAs and other gadgets
are usually limited to WPA + TKIP.
•
WPA2 is an advanced option. WPA2 support on Windows requires a Microsoft patch and is only
available on Windows XP with Service pack 2 or later.
•
WPA-Auto is an advanced option. Only the best WPA 802.11i-conforming/Wi-Fi WPA-certified
client devices can operate in this mode.
•
WPA Authentication
: PSK is suitable for home/personal use. 802.1X uses the network RADIUS
server to verify user identity. The Auto mode offers both options to the wireless client to pick.
•
WPA Algorithm
: When Auto is selected, the wireless client decides whether TKIP or AES will
be used. AES is the strongest encryption and requires additional hardware support on wireless
devices.You should consult the documentation of your wireless client devices. Auto is an
advanced option and some wireless clients may fail to associate.
•
Passphrase
: Enter a new passphrase between 8 and 32 characters long, using any combination
of printable characters (letters, numbers, hyphens and underscores).

Customizing 802.1X Settings
If you choose “WPA” as the encryption method, you have the option to set up the Metro Broadband Gateway
to act as an 802.1X proxy, utilizing external authentication sources such as a RADIUS server. This provides
a higher level of security, when compared to the static security process in a WEP configuration.Using
802.1X lets a device complete authentication prior to the exchange of data.
To configure WLAN-specific 802.1X authentication settings, follow these steps:
1.
Open the Web User interface, and click
Wireless
under Configuration.
2.
When the Configure :: Wireless :: Common workspace appears, click the
Metro WLAN
tab.
3.
When the workspace appears, open the
Encryption Method
menu and choose
WPA
. The basic set of
WPA-specific encryption options appear in this workspace.

Certificate Management
Certificate management can be a part of two-factor authentication in your environment. In conjunction with
other security requirements that you know (“what I know”), such as a user name and password, using a
certificate fills the “what I have” requirement in two-factor authentication.
To manage certificates, follow these steps:
1.
After selecting WPA and 802.1X settings under the Metro WLAN workspace, click the
Certificate
Management
link. The “Cert Management” screen appears.
