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

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

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.
