The MAC address designates the hardware
interface of each individual network device
uniquely (e.g. the WLAN adapter of a com-
puter or the Ethernet port of a printer). It con-
sists of six double-digit
numbers, each separated by a colon (e.g.
00:0B:3B:37:9D:C4). In general, the MAC
address is on the housing of the device.
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
enter the MAC address of your own
computer if you are connected to
the dLAN 200 AVpro Wireless N not
via the Ethernet port, but via WLAN.
Otherwise you will block your own
access to the device via WLAN by
activating the WLAN filter!
Security (encryption)
Without encryption, not only are all data transmitted
from
dLAN 200 AVpro Wireless N in your wireless network
hexadecimal
without protection, but there is also no password
prompt to establish the connection. If no other security
measures were set up, such as a WLAN filter (see Chap-
ter WLAN filter), third parties can gain access to your
network at any time and, for example, share your Inter-
net connection. Usually this happens without you no-
ticing it.
