Use a WLAN connection

You can use a wireless LAN (WLAN) data connection to
connect to the internet. Only one connection to one wireless
LAN can be active at a time, but several applications can use
the same internet access point.
About WLAN
To use a wireless LAN (WLAN) connection, it must be available
in the location, and your device must be connected to the
WLAN. Some WLANs are protected, and you need an access
key from the service provider to connect to them.
There might be some restrictions for Wi-Fi use in some
countries. Check with your local authorities for more
information.
Features that use WLAN, or that are allowed to run in the
background while using other features, increase the demand
on battery power and reduce the battery life.
Your device supports the following WLAN features:
IEEE 802.11b/g standard
•
Operation at 2.4 GHz
•
Wired equivalent privacy (WEP) with keys up to 128 bits,
•
and Wi-Fi protected access (WPA2-Enterprise)
authentication method. These functions can be used only
if they are supported by the network.
Important: Always enable one of the available encryption
methods to increase the security of your wireless LAN
connection. Using encryption reduces the risk of
unauthorized access to your data.
