The Wireless LAN Adapter is approved to create a wireless LAN network to send data and e-mail messages, to browse on the Internet, and to establish connections with other computers.

Data connections can be made from most locations where your Wireless LAN Adapter operates. However, it is recommended that you move the Wireless LAN Adapter to a location where the strongest possible network signal can be obtained. When the signal is strong, data transmission is efficient.

The following factors may impair wireless connections:

Noise

Radio interference from electronic appliances and equipment, as well as from other wireless devices in areas where wireless devices are prevalent.

Handover

As the Wireless LAN Adapter user moves from one network cell to another, the signal strength of the channel drops and the network may hand the user over to a different cell and frequency, where the signal is stronger. A cell handover may also occur when the user is stationary due to varying network traffic loads.

Electrostatic discharge

A discharge of static electricity from a finger or a conductor may cause erroneous functions in electric devices. The discharge may result in unstable software operation. Network connections may become unreliable, data may be corrupted, and the transmission halted. In this case, end the existing connection (if any) and restart the unit by powering off and on again.

Dead spots and dropouts

Dead spots are areas where radio signals cannot be received. Dropouts occur when the Wireless LAN Adapter user passes through an area where the radio signal is blocked or reduced by geographic or structural obstructions.

Signal impairment

Distance and obstacles can cause out-of- phase reflected signals that result in a loss of signal strength.

Low signal strength

Due to either distance or obstacles, the radio signal strength from a network cell may not be strong or stable enough to provide a reliable wireless connection for communication. Therefore, to ensure the best possible communication, remember to consider the following points:

•Data connection works best when the Wireless LAN Adapter is in a stationary position.

•Do not place the Wireless LAN Adapter on a metal surface.
