Chapter 3 Using the Wireless Utility
The GN-WB31N-RH Wireless Utility is a powerful application that helps you to configure
the Adapter and monitor the statistics of the communication link. It also permits the
configuration for parameters while the Adapter is operating – no restarting is required. It
also offers more configuration options than does Windows native Zero Wireless
Configuration. It appears as the “G” icon in the task bar at the bottom right corner of
screen whenever the Adapter is in operation (see Figure 3-1). The quick start icon also
doubles as a signal strength monitor, as indicated by its four small green lights.
Figure 3-1. GN-WB31N-RH Wireless Utility quick start icon
To open the GN-WB31N-RH Utility, double click the quick start icon located in your system
tray. Or, go to Windows Start menu, select Programs, Gigabyte Wireless Network
Adapters, GN-WB31N-RH and then GN-WB31N-RH Utility.
Note: You may only use the utility to change wireless configurations when the
GN-WB31N-RH is enabled and operating. You have to use Windows native Zero
Configuration tool provided with Windows when the Adapter is not enabled.
Opening the GN-WB31N-RH Wireless Utility, you are presented with the Profile Tab.
There are 5 main tabs with which to control and monitor your GN-WB31N-RH – Profile,
Link, Site Survey, Statistics and the About Tab. The following sections will cover each tab
in detail.
3.1.Profile Tab
The Profile tab shows you the current association information about the profile. (see
Figure 3-2). Profiles are useful if you often associate with different access points. You
can configure a group of settings depending on the access point you often associate with
and save as a profile, Click the Add button to create a new profile (see section below for
further details), the Delete button to delete a selected profile, the Edit button to modify a
selected profile and click the Activate button to have a selected profile become active.

Figure 3-2. Current profile
Description of items in Figure 3-2 is as follows:
Profile Name: A profile can be saved for various wireless settings in different
environments, i.e. home, office, and the corner coffee shop.
SSID: The Network Name of the wireless router or Access Point.
Channel: Shows the current wireless channel.
Authentication: Sever authentication types. They include “OPEN”, “Shared”, “LEAP”,
“WPA”, “WPA-PSK”, “WPA2” and “WPA2-PSK”.
Encryption: The type of encryption used in this profile: “None”, “WEP”, “AES” and “TKIP”.
Network Type: Informs you if an Access Point (infrastructure) or Ad Hoc is connected. In
Ad Hoc, you may select a channel for each member participating in Ad Hoc.

1
3-1-1. Configuration Screen
If you want to ADD new profiles, or EDIT existing ones, the Configuration screen will open.
Here you will Name your profile, and if you like, select an alternate network type (Ad hoc),
restrict on SSID connections and more. All three tabs shown (see Figure 3-3) are related,
so when you’re done with all three (Configuration, Authentication, Advanced) tabs, click
OK.
Figure 3-3. Configuration
Description of items in Figure 3-3 is as follows:
Profile Name: Users can save different profiles names for different configurations.
SSID: Select the AP detected by the system from the drop-down menu or input a SSID.
(Default: ANY)
Power Saving mode: Select “Power Saving Mode” (PSM) to turn off the Adapter’s
transceiver when not in use, or select CAM to continuously turn on transceivers. (Default:
OFF)
Network Type: “Infrastructure” and “Ad Hoc”. When Infrastructure network type is chosen,
PSM will function but not Preamble. On the contrary, when Ad hoc type is chosen,

2
Preamble will function but not PSM. Also, the Channel option will appear and 802.1X
Authentication will be disabled. (Default: Infrastructure)
TX Power: Select percentage of transmitted power. (Default: Auto)
RTS Threshold: This is a mechanism implemented to prevent the “Hidden Node” problem,
“Hidden Node” is a situation in which two stations are within range of the same Access
Point, but are not within range of each other. Therefore, they are hidden nodes for each
other and can not detect each other. This mechanism is a way to prevent data collision
when Adapters require transmission. (Default: OFF)
Fragment Threshold: Fragmentation mechanism is used for improving the efficiency
when high traffic flows along in the wireless network. (Default: OFF)
3-1-2. Authentication and Security Screen:
If an authentication or security setting is configured in your Access Point or router, you
must enable this function to ensure successful connection. Use the following tab to
configure data security and ID authentication (see Figure 3-4). You may configure
different settings in the profile, including 802.11 Protocol Authentication and Security and
802.1X Protocol.
Figure 3-4. Authentication and Security

3
Authentication Type: Before a station connects to a SSID, the authentication type used
by the SSID must be known. Authentication types include OPEN SYSTEM, WPA,
WPA-PSK, WPA2, WPA2-PSK, LEAP and SHARED.
Encryption: To prevent unauthorized access to data transmitted on the network, the
Adapter and the Access Point agree on a type of data encryption. Any station that wishes
to connect must have the same password and encryption scheme to connect. Different
authentication types have different level of security. (Default: TKIP)
WEP encryption: Select one of the four keys as the default encrypted key.
To setup WEP, you will need to set a ASCII or HEX key to connect to Access Point. The
WEP Key can only be saved through the setting of profile.
1. Select a Key #.
2. Select a form of the key (Hex or ASCII).
3. Enter password. Please enter 26 hexadecimal digits or 13 ASCII digits.
4. Click OK to save the settings.
Making HEX keys:
64-bit - Generated as 10 alphanumeric characters (0-9, a-f) (example: 843c29a562)
128bit - Generated as 26 alphanumeric characters (0-9, a-f) (example:
3c29f2536bef3276d32e364a2c)
Note: Using a Hex key is more secure than using an ASCII key, and if you are connecting
to a GIGABYTE Router or Access Point, ASCII keys are not allowed and you must use a
Hex key.
WPA-PSK/WPA2-PSK encryption: WPA-PSK/ WPA2-PSK (Preshared Key) uses TKIP
or AES based on your choice. You create a password (or Passphrase as its often called)
and the system will use the Passphrase to create a cipher code in which it will encrypt the
data.
To use WPA-PSK/ WPA2-PSK:
1. Create a Passphrase, and key it in. Use 8~63 ASCII digits.
2. Remember this Passphrase. If you forget the Passphrase, you will have to do a
hard reset of the Access Point in order to restore default settings and connect
again.
3. Click “OK to save these settings.
3-1-2-1. 802.1X Setting - Certification Tab
Clicking Use 802.1X Authentication and then Enter 802.1X configuration from the
Authentication and Security Window will bring up the 802.1x Setting Window and the
Certification Tab (see Figure 3-5).
From the Certification screen, you may configure information about authentication, such as
Tunnel Protocol, ID and Password and Client Certificate or Certificate Chain. (see Figure
3-5 and 3-7)

4
Figure 3-5. 802.1X Authentication
Description of items in Figure 3-5 is as follows:
Authentication type: PEAP, TLS/Smart Card, TTLS and MD5-Challenge. (Default:
PEAP)
Session Resumption: This feature can create a new connection without the overhead of
a full handshake.
Identity: The Account’s User ID.
Password: Passwords for users accounts can be used when LEAP and MD5-Challenge
are selected as authentication types.
Use Client Certificate: This certificate is necessary for TLS and an option for PEAP and
TTLS. Check “Use Client Certificate” to verify the authenticity of a Client Certificate during
the authentication process.
Clicking More will open the Client Certificate Selection Window (shown in Figure 3-7).
Users can select one suitable certificate as Client Certificate. (Default: OFF)
Tunnel Authentication: PEAP and TTLS use two-step authentication method. The first
step is that Server sets up a Tunnel with its authentication. No option is need to be
set for Client (the PC with the Adapter). The second step is to confirm the validity of
Client with assigned authentication type in the Tunnel. Data needed for
authentication includes Tunnel ID, Tunnel Password, Client Certificate or Server
Authentication.

5
Protocol: Use assigned authentication type in the safe tunnel.
Tunnel ID: Users’ accounts.
Password: Passwords for users’ accounts.
Figure 3-6. Client Certificate Selection List

1
3-1-2-2. 802.1x Settings - CA Server Tab
CA Server is used when TLS, TTLS or PEAP is in use. When Use certificate chain is
checked, the Client can verify if such server is reliable and then transmit Client Certificate
after the verification is confirmed.
Figure 3-7. CA Server Setting
To verify the CA server:
1. Confirm if the Server Certificate is issued by assigned certificate issuer. If “Allow
Intermediate Authentication” is checked, the server certificate can be issued by
one intermediate certificate issuer.
2. Check the server name of server certificate is the same as the name entered by
the user or belongs to the same domain.
Use certificate chain: If “Use certificate chain” is checked, it indicates that Client will
confirm whether CA server is reliable. (Default: OFF)
Certificate issuer: CA of a server certificate can be selected from certificate issuers on
the drop-down list. (Default: ANY)
Allow intermediate Certificates: When this option is checked, the certificate issuer can
be an issuer recognized by a specific certificate issuer. On the other hand, the server
certificate must be issued by a certificate issuer selected by the user.
Server name: This value can be a server name or the name of a domain where the server
is located.

2
Server name must match exactly: If this option is selected, the server name of server
certificate must be the same as “Server Name” or as the name of domain where the server
is located.
Domain name must end in specified name: If this option is selected, the certificate
issuer must be the domain or secondary domain entered in “Server Name”.
3-1-3. Advanced Screen
