Configuring WiFi-b
™
by Wireless Settings utility
The Wireless Settings utility allows you to set your WiFi-b™ card in Station (STA) or Soft Access Point (Soft AP) mode. In STA mode, your WiFi-b™ connects to an access point to access a wireless network or the Internet. In Soft AP mode, your
WiFi-b™ transmits and receives signals to and from other WiFi devices in a wireless network. The Soft AP feature is available only on systems running on
Windows ® XP.

Internet Connection Sharing (ICS)
After setting the WiFi-b™ card on Soft AP mode, you may enable Internet
Connection Sharing (ICS). ICS is a Windows ® XP feature allowing several computers in a wired or wireless network to share a single Internet connection.
With ICS, other wireless clients in a home or small office network rely on the
WiFi-b™ for Internet access. Follow these instructions to enable ICS.
4.5.1
Connect to the Internet using a broadband connection that is always on
To enable ICS if your computer connects to the Internet using a broadband that is always on:
1. Open the Wireless Settings utility.
Select Config from the property window, then select the Soft AP tab.
2. Select the built-in 3Com Gigabit LAN connection from the Available
Network Connections field, then drag it to the Internet field.
3. Check Enable ICS and Enable
Firewall, then click Apply.
4. Click OK when this dialog box appears.
5. An Internet Sharing Configuration dialog box appears. Click Yes. The
Internet network connection and the
WiFi-b™ card is bridged. See section
4.6 “Network Bridge” for details.
Wireless clients must be set to Infrastructure network type and STA (station) mode to connect to the Internet via the soft AP. The SSID and WEP keys of client computers must be identical with that of the soft AP.

Network Bridge
Host computers with multiple network adapters may use the network bridge function to connect several LAN segments. A LAN segment is a physical connection between a host computer and a client computer. Network bridging is a cost-effective method of connecting LAN segments since it does not require expensive hardwares such as routers and technical expertise for configuring
Internet protocol (IP) addresses. Network bridge is essential in enabling ICS among wireless clients in a home network.
You must have Administrator privileges before you could create a network bridge.
To bridge a wired network connection to the WiFi-b™:
1. Open the Wireless Settings utility.
Select Config from the property window, then select the Soft AP tab.
2. Select a network connection from the
Available Network Connections box, then drag the connection to the
Internet field. Click Apply.
Chapter 4: Utility information 4-19
3. A warning message appears. Click OK.
4. The Wireless Settings utility displays the wired and wireless network connections to be added in a network bridge based on your configuration.
Write down these network connections in a piece of paper. Click OK.
5. Select the network connections to be bridged. Press the Control key while clicking the network connection icons to select. Right-click on any selected network icon to open a drop-down menu. Select Bridge Connections.
6. Wait while the selected network connections are bridged.
7. The bridged network connections are displayed in the Network
Connections window.

Problem Action
I cannot connect to an Access
Point.
3. Restart your computer and repeat the WiFi-b™ software installation following the instructions contained in this User Guide.
• Check if the Network Type of the
WiFi-b™ card is set to
Infrastructure mode.
• Check if the WiFi-b™ has the same Service Set Identifier
(SSID) as that of the AP.
• Check if the WiFi-b™ card and the
AP have the same Encryption. If
WEP encryption is enabled, set the same WEP keys for the
WiFi-b™ and the AP.
• Check if the MAC address of the
WiFi-b™ card is added in the AP
Authorization Table. Inquire this with your LAN administrator.
• There is poor signal reception.
Re-orient the WiFi-b™ antenna.
I can connect to an Access Point but I cannot connect to the
Internet.
• Check if the WiFi-b™ card and the
AP have the same Encryption. If
WEP encryption is enabled, set the same WEP keys for the
WiFi-b™ and the AP.

Encryption. If WEP encryption is enabled, set the same WEP keys for the WiFi-b™ and the AP.
• There is poor signal reception.
Place the WiFi-b™ antenna nearer to the station.
I cannot connect to other computers linked via an Access
Point or Ad Hoc network.
• Check if the WiFi-b™ card and the other APs and/or clients have the same Encryption. If you enable
WEP encryption, you must set the same WEP keys for the WiFi-b™ card and the other AP/s and/or clients.
• Check the TCP/IP settings (IP address, subnet mask, gateway, and DNS) of your computer.
• Enable file and printer sharing in each client computer to allow file sharing.
I always have poor link quality and low signal.
Observe the following to achieve better link quality and stronger signal:
• Keep the WiFi-b™ away from microwave ovens and large metal objects to avoid radio interference.
• Reorient the WiFi-b™ antenna.
• Shorten the distance between the
WiFi-b™ card and the AP/station.
