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). But in
France
, you have to use
channels 10
or
11
(indoor and outdoor). In the
Netherlands
, you have to use channels
9
,
10
or
11
(outdoor).
You need to change the channels in case of an
ad-hoc
network. You cannot select a channel for an
infrastructure network; in that case, you have to use a channel configured on the wireless access point.
To change channels, proceed as follows:
1

When you change the channel number on one computer, you need to change the channel number manually on all other devices intended for wireless

If you use a non-Sony Access Point, read the manual of the Access Point to be sure which channel to use.
