Why selecting a WiFi channel?

To communicate, all the components of a WiFi network must use the same channel. In the WiFi network in infrastructure mode (using an access point), it depends on the channel set at the access point.
However, most people leave the default channel, which means that several wireless networks using the same channel and share the good connection.

For better results when using WiFi, it is necessary to adjust the channel on the access point, as well as configured on the client, to take the least used channel in your neighborhood.

To do this, you can use software such as NetStumbler, which will list the neighborhood wifi networks and channels used. Note the channels most frequently used to select one as free as possible.
