Troubleshooting

I plugged in the 802.11g 54Mbps USB Adapter but I do not see the Configuration Utility icons.
Possible Solution:
If you installed the 802.11g 54Mbps USB Adapter without installating the software and drivers first, you will not see the Configuration Utlity.

Click 802.11g 54Mbps USB Adapter Utility and Drivers. Follow the on-screen instructions to finish the installation procedure. If you are prompted, restart your computer.

Windows could not locate the drivers for the 802.11g 54Mbps USB Adapter.
Possible Solution:

I cannot connect to the Internet.
Possible Solution:
Check the Configuration Utility icon for the 802.11g 54Mbps USB Adapter in the system tray to confirm the connection status. If you are connected to your Wireless Router, the icon will be green or yellow. If the icon is red, open the Configuration Utility and scan the area so that you can connect to the correct wireless network.

Possible Solution:
Try performing the ping procedure to make sure you can connect with different areas of the wireless network and the Internet. If at any time during the ping procedure you do not receive a return message for a successful ping, this means that you cannot connect to that IP address. After you have made the corrections, continue with the ping procedure.

1. Click Windows Start and then click Run. In the Run dialog box, Windows 98 and Me users should type command and click OK. Windows 2000 and XP users should type cmd and click OK.
2. At the command prompt, type Ping 127.0.0.1 This is your local host address and this will ensure that the TCP/IP protocol is installed and functioning properly. If you cannot complete this ping, reinstall the TCP/IP protocol on your computer. Refer to your operating system’s documentation for instructions.
3. Type Ping followed by your IP address. To determine your IP address, refer to the previous Possible Solution. This will ensure that your computer is responding to requests and that the 802.11g 54Mbps USB Adapter is properly installed. If you cannot complete this ping, uninstall the 802.11g 54Mbps USB Adapter and repeat the installation procedure.
4. Type Ping followed by your gateway address to check the communication with your gateway. The default gateway address is the IP address of your wireless router or access point. Check your Wireless Router to verify this address. This will ensure that you can connect to the Wireless Router. If you cannot complete this ping, make sure your wireless settings are correct and that the 802.11g 54Mbps USB Adapter is fully inserted into a USB port on your computer.
5. Type Ping followed by the outside Internet address that is provided by your ISP. This procedure will ensure that your wireless network can connect to the Internet. If you cannot complete this ping, verify your Internet connection between your modem and your wireless router or access point.
6. Type Ping followed by your known DNS server address. This will allow you to resolve valid Internet host names to IP addresses and to verify that you can access the Internet.
