Selecting a channel
When using Wireless LAN, radio frequencies are used to transmit data from one computer to another. Radio
frequencies are divided into several channels (1 to 14). However, in France, you have to use channels 10 or
11 (indoor and outdoor) and in the Netherlands, you have to use channels 9, 10 or 11 (outdoor).
