E51 User Guide - Nokia

To use WLAN, you must create an internet access point in a
WLAN. Use the access point for applications that need to
connect to the internet. A WLAN connection is established
when you create a data connection using a WLAN access
point. The active WLAN connection is ended when you end
the data connection. You can also end the connection
manually. See "Connection manager", p. 101.
You can use WLAN during a voice call or when packet data is
active. You can only be connected to one WLAN access point
device at a time, but several applications can use the same
internet access point.
When the device is in the Offline profile, you can still use
WLAN, if available. Remember to comply with any applicable
safety requirements when establishing and using a WLAN
connection.
If you move the device to another location within the WLAN
and out of range of a WLAN access point, the roaming
functionality can automatically connect your device to
another access point that belongs to the same WLAN. As long
as you remain within range of access points that belong to
the same network, your device can stay connected to the
network.
Tip: To check the unique media access control (MAC)
address that identifies your device, for example to
configure the MAC address of your device to a WLAN
router, enter *#62209526# on the device keypad. The
MAC address is shown on the device display.

Always enable one of the available encryption methods to
increase the security of your WLAN connection. Using
encryption reduces the risk of unauthorised access to your
data.
