Troubleshooting

This chapter offers some suggestions to solve problems you might encounter. The potential problems are divided into the following categories.

• Power, Hardware Connections, and LEDs

• Accessing the Utility

• Link Quality

• Problems Communicating with Other Computers

6.1 Power, Hardware Connections, and LEDs

V The NWD210N does not turn on. None of the LEDs turn on.

1 Make sure the NWD210N is correctly installed (refer to your Quick Start Guide). 2 Restart the computer to which the NWD210N is attached. 3 If the problem continues, contact the vendor.

V One of the LEDs does not behave as expected.

1 Make sure you understand the normal behavior of the LED. See Section 1.1 on page 21. 2 Check the hardware connections. See the Quick Start Guide and Section 1.1 on page 21. 3 Restart the computer to which the NWD210N is attached. 4 If the problem continues, contact the vendor.

6.2 Accessing the Utility

V I cannot access the Utility

NWD210N User’s Guide

Chapter 6 Troubleshooting

1 Make sure the NWD210N is properly inserted and the LEDs are on. Refer to the Quick

Start Guide for the LED descriptions.

2 Use the Device Manager to check for possible hardware conflicts. Click Start, Settings,

Control Panel, System, Hardware and Device Manager. Verify the status of the

NWD210N under Network Adapter (steps may vary depending on the version of Windows).

3 Install the NWD210N in another computer. 4 If the error persists, you may have a hardware problem. In this case, you should contact

your vendor.

6.3 Link Quality

V The link quality and/or signal strength is poor.

1 Scan for and connect to another AP with a better link quality using the Site Survey

screen.

2 Move your computer closer to the AP or the peer computer(s) within the transmission

range.

3 There may be too much radio interference (for example from a microwave oven, or

another AP using the same channel) around your wireless network. Lower the output power of each AP.

4 Make sure there are not too many wireless stations connected to a wireless network.

6.4 Problems Communicating with Other Computers

V The computer with the NWD210N installed cannot communicate with the other

computer(s).

In Infrastructure Mode

• Make sure that the AP and the associated computers are turned on and working properly.

• Make sure the NWD210N computer and the associated AP use the same SSID.

• Change the AP and the associated wireless clients to use another radio channel if interference is high.

• Make sure that the computer and the AP share the same security option and key. Verify the settings in the Profile Security Setting screen.

• If you are using WPA(2) or WPA(2)-PSK security, try changing your encryption type from TKIP to AES or vice versa.

In Ad-Hoc (IBSS) Mode

NWD210N User’s Guide

Chapter 6 Troubleshooting

• Verify that the peer computer(s) is turned on.

• Make sure the NWD210N computer and the peer computer(s) are using the same SSID and channel.

• Make sure that the computer and the peer computer(s) share the same security settings.

• Change the wireless clients to use another radio channel if interference is high.

APPENDIX A

Setting up Your Computer’s IP

Address

" The purpose of this appendix is to show you how to configure an IP address

on your computer depending on what operating system you have. It does NOT mean that your NWD210N supports all these operating systems. To see what operating systems your NWD210N supports, refer to Chapter 7 on page 77.

All computers must have a 10M or 100M Ethernet adapter card and TCP/IP installed.

Windows 95/98/Me/NT/2000/XP/Vista, Macintosh OS 7 and later operating systems and all versions of UNIX/LINUX include the software components you need to install and use TCP/ IP on your computer. Windows 3.1 requires the purchase of a third-party TCP/IP application package.

TCP/IP should already be installed on computers using Windows NT/2000/XP, Macintosh OS 7 and later operating systems.

After the appropriate TCP/IP components are installed, configure the TCP/IP settings in order to "communicate" with your network.

If you manually assign IP information instead of using dynamic assignment, make sure that your computers have IP addresses that place them in the same subnet as the NWD210N’s LAN port.

Windows 95/98/Me

Click Start, Settings, Control Panel and double-click the Network icon to open the Network window.
