Chapter 23 Troubleshooting 138
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 b
y o
ther 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 w
ireless 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
wir
eless client is sending or receiving a lot of information, it may have too many programs open
that use the Internet.
