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 and an infrastructure network.
To change channels, proceed as follows:
1 Click Start and then Control Panel.
2 Double-click System.
The System Properties dialog box appears.
3 On the Hardware tab, click Device Manager.
The Device Manager window appears.
4 Double-click Network adapters.
The list of available network adapters appears.
5 Right-click LAN-Express IEEE 802.11 PCI Adapter and select Properties.
The LAN-Express IEEE 802.11 PCI Adapter Properties dialog box appears.
6 On the Advanced tab, select Channel.
Use default channel appears in the Value screen.
7 Set the Value to the correct channel.
- France: only 10 or 11 (whether used indoor and outdoor).
- the Netherlands: 9, 10, 11 (when used outdoor).
8 Click OK.
The correct channel has been set.
✍ When you change the channel number on one computer, you need to change the channel number manually on all other devices intended for wireless
connection.
If you use a non-Sony Access Point, read the manual of the Access Point to be sure which channel to use.
