Devolo DLAN 200 AV Wireless N User Manual page 34

The WLAN filter should be used only as
an additional option. By using it you
could limit access to your wireless net-
work, but without encryption it would
be relatively easy for third parties to
eavesdrop on all of your data transmis-
sions.
To use the WLAN filter, enable the option Enable fil-
ters. Now you can enter various network devices by
means of what is known as your MAC address for ac-
cess to your dLAN 200 AV Wireless N. Confirm each
entry with Add. Network devices or stations connected
to your dLAN 200 AV Wireless N are automatically list-
ed, that is, to enable an already connected station for
the dLAN 200 AV Wireless N, simply select the MAC
address of the respective device and confirm it with
Add. This then appears under Approved WLAN sta-
tions. To remove an enabled station, select its MAC
address and confirm it with Delete.
The MAC address designates the hardware
interface of each individual network device
uniquely (e.g. the WLAN adapter of a compu-
ter or the Ethernet port of a printer). It con-
sists of six double-digit hexadecimal
numbers, each separated by a colon (e.g.
00:0B:3B:37:9D:C4). The MAC address is on
the housing of the device.
Network configuration 33
You can easily determine the MAC address of a Win-
dows computer by opening the window with the com-
mand prompt under Start
Accessories Command Prompt. Enter the com-
mand IPCONFIG /ALL here. The MAC address is dis-
played under the designation Physical address.
After entering the MAC addresses, do not forget to
click the Save button. If the entered values are incor-
rect (e.g. because the colons are missing), a corre-
sponding error message is displayed.
Keep in mind that you also have to en-
ter the MAC address of your own com-
puter if you are connected to the
dLAN 200 AV Wireless N not via the
Ethernet port, but via WLAN. Other-
wise you will block your own access to
the device via WLAN by activating the
WLAN filter!
