devolo dLAN 500 AV Wireless+

Keep the following in mind if you
would like to use doubled channel
width (utilising 40 MHz channels): The
potential transfer rate is 300 Mbps in-
stead of 150 Mbps when using wire-
less channels with doubled channel
width, but increased interference can
occur due to neighbouring access
points.

Security

Without encryption, not only are all data transmitted
from client computers to the dLAN 500 AV Wireless+
in your wireless network without protection, but there
is also no password prompt to establish the connec-
tion. If no other security measures were set up, such as
a WLAN filter (see Chapter 6.5.3 WLAN filters), third
parties could gain access to your network at any time
and, for example, share your Internet connection. Each
instance of access is visible to you in the WLAN monitor
(see Chapter 6.3.2 WLAN monitor).

To secure the data transmission in your wireless net-
work there are two security standards available.

The older and weaker WEP standard can protect
communication with the help of a key having
either 10 or 26 characters. To do so, enter a

series of hexadecimal characters with the corre-
sponding number of characters into the Key field.

The state-of-the-art WPA and WPA2 (Wi-Fi Pro-
tected Access) methods allow individualised keys
consisting of letters and numbers with a length
of up to 63 characters. You can simply enter this
using the keyboard, without having to convert it
into hexadecimal format first (as with WEP).
Under Mode, you can limit access of clients to the
dLAN 500 AV Wireless+ to the method you have
selected.

Save all modified settings before leaving this configu-
ration area again.

You should always encrypt the connec-
tions in your WLAN. Otherwise anyone
within range could penetrate into your
home network and, for example, share
your Internet connection. If possible,
always select the better WPA2 encryp-
tion method. Only use WEP if one of
your wireless terminal devices does not
operate with a better standard.
