Regulatory Information

Wireless communication is often subject to local radio regulations. Although AirStation

wireless networking products have been designed for operation in the license-free 2.4 GHz

band, local radio regulations may impose limitations on the use of wireless communication

equipment.

Network Compatibilty

Draft-N support built off of the Draft Specification 3.0 for 802.11n.

IEEE802.11g/b Standard for Wireless LANs.

Host Operating System

Microsoft Windows® 2000/XP/Vista, Unix, Linux and MacOS

Media Access Protocol

Wired - CSMD/CD (Collision Detection)

Wireless - CSMD/CA (Collision Avoidance) with Acknowledgment (ACK)

Common Problems

• Out of range, client cannot connect to the AirStation.

• Configuration mismatch, client cannot connect to the AirStation.

• Absence or conflict with the Client Driver.

• Conflict of another device with the AirStation hardware.

LED Activity

Monitoring LED activity helps identify problems.

• Power LED should be Green when the AirStation is on.

• The Security LED lights when encryption or authorization is turned on.

• Wireless LED should be Green if the line is active. If is it blinking Green, wireless

communication is active.

• Router LED should be Green (100Mbps) or Amber (10Mbps) while communication is

active.

• The Red Diag LED will flash during boot and firmware updates.

DIAG LED Activity

Unplug the power for three seconds. Plug the power back in to monitor the Diag LEDs

during start-up.

LEDs Work But Client PC Cannot Connect to Network

If the LEDs indicate that the network is working properly (Power LED is on, Transmit/

Receive LED blinks), check the TCP/IP settings of the network.

Changing Client TCP/IP Settings in Windows

Consult the LAN Administrator for correct TCP/IP settings.

To add or change TCP/IP Settings:

1. On the Windows task bar, click Start.

2. Select Settings, then Control Panel.

3. Double-click on the Network icon to view Network Properties.

4. From the list of installed components, verify the “TCP/IP - wireless LAN adapter”

protocol is installed.

Troubleshooting

±¸

•

If the wireless adapter protocol is not yet installed, click the

Add

button and select

the TCP/IP protocol from the list. Refer to Windows Help for more information.

•

If the wireless adapter protocol is installed, select the protocol and click the

Properties

button. Verify that the parameters match the settings provided by your

LAN Administrator. Make changes if necessary, and click OK.

5. If prompted, restart your computer.
