Chapter 23 Troubleshooting

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.

provider.
