Chapter 30 Troubleshooting

Building Materials: metal doors, aluminum studs.

Electrical devices: microwaves, monitors, electric motors, cordless phones, and other wireless devices.

To optimize the speed and quality of your wireless connection, you can:

Move your wireless device closer to the AP if the signal strength is low.

Reduce wireless interference that may be caused by other wireless 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 wireless client.

Reduce the number of wireless 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 wireless client is sending or receiving a lot of information, it may have too many programs open that use the Internet.

Position the antennas for best reception. If the AP is placed on a table or floor, point the antennas upwards. If the AP is placed at a high position, point the antennas downwards. Try pointing the antennas in different directions and check which provides the strongest signal to the wireless clients.
