PART II
Troubleshooting and Appendices

CHAPTER 2 Troubleshooting

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

• Power and Hardware Problems
• WiFi Problems

Power and Hardware Problems

The NWD7605 does not turn on.

1. Make sure the NWD7605 is correctly installed (refer to your Quick Start Guide).
2. Restart the computer to which the NWD7605 is attached.
3. If the problem continues, contact the vendor.

The LED does not behave as expected.

1. Make sure you understand the normal behavior of the LED. See Table 1 on page 10.
2. Check the hardware connection. See the Quick Start Guide.
3. Restart the computer to which the NWD7605 is attached.
4. If the problem continues, contact the vendor.

WiFi Problems

The WiFi connection is slow or intermittent.
The following factors may cause interference:

• Obstacles: walls, ceilings, furniture, and so on.
• Building Materials: metal doors, aluminum studs.
• Electrical devices: microwaves, monitors, electric motors, cordless phones, and other WiFi devices.
• To optimize the speed and quality of your WiFi connection, you can:
• Move your WiFi device closer to the AP/router if the signal strength is low.
• Reduce WiFi interference that may be caused by other WiFi networks or surrounding wireless electronics such as cordless phones.
• Place the AP where there are minimum obstacles (such as walls and ceilings) between the AP and the WiFi client.
• Reduce the number of WiFi clients connecting to the same AP simultaneously, or add additional APs if necessary.
• Try closing some programs that use the Internet, especially peer-to-peer applications. If the WiFi client is sending or receiving a lot of information, it may have too many programs open that use the Internet.
