Wireless LAN Connection Troubleshooting

Whenever you experience problems with the wireless LAN connection between the Data Projector and the computer, check the following points first.

Check the following on the computer.

•Did you disable “Network Connection” before connecting the YW-2 wireless LAN adapter to your computer’s USB port?

On the Windows Control Panel, click “Network Connections” (“Network and Dial-up Connection” in the case of Windows 2000). If you see “Local Area Connection”, “Wireless Network Connection” or “Network Bridge” on the window that appears, right- click the icon and then click “Disable”.

•Is a wireless LAN utility other than Wireless Connection (which comes with the Data Projector) running?

If so, shut down the other utility.

Check the following on the Data Projector.

•Is the same connection profile selected on the computer and on the Data Projector?

Wireless LAN connection is not possible when different connection profiles are selected on the computer and the Data Projector (such as “Manual Connection 1” on the computer and “Simple Connection 1” on the Data Projector). Make sure the same connection profile is selected on both.

Also check the following.

•Are the Data Projector and computer too far apart or are they separated by a wall or other barrier?

Try moving the Data Projector and computer so they are closer to each other.

•Is a microwave oven or a Bluetooth device being used nearby?

Operation of a device that uses the 2.4 GHz frequency band (which is the same frequency band as the IEEE802.11b wireless standard used by the Data Projector) in the vicinity of the Data Projector can cause radio interference, resulting in a wireless communication error. Avoid using the nearby microwave oven or Bluetooth device when performing Data Projector wireless LAN communication.

If the above countermeasures do not resolve your problem, try the following depending on the problem you are experiencing.
