LANCOM 1811n Wireless – LANCOM 1821n Wireless
Chapter 8: Security settings
Standard encryption with WPA- PSK
The factory settings (or those after resetting the device) are different in LANCOM Access Points
than in LANCOM Wireless Routers.
Unconfigured Access Points with standard factory settings cannot be commissioned by
means of the WLAN interface. The WLAN modules are switched off and the devices search
the LAN for a LANCOM WLAN Controller which will supply a configuration profile.
Unconfigured Wireless Routers with standard factory settings cannot be commissioned by
means of the WLAN interface. Furthermore, encryption with WPA-PSK as described here
is used as standard.
The preshared key (PSK) for the standard WPA encryption consists of the first letter "L" follo-
wed by the LAN MAC address of the access point in ASCII characters. The LAN MAC addresses
of the LANCOM devices always begin with the character string "00A057". You will find the
LAN MAC address on a sticker on the base of the device. Only use the number labeled as
"MAC address" that starts with "00A057". The other numbers that may be found are not the
LAN MAC address.
A device with the LAN MAC address "00A05713B178" thus has a preshared key of
"L00A05713B178". This key is entered into the 'WPA or private WEP settings' of the device
for each logical WLAN network as 'Key 1/Passphrase'.
To use a WLAN adapter to establish a connection to a LANCOM Wireless Router that has fac-
tory settings, the WPA encryption must be activated for the WLAN adapter and the standard
13-character preshared key.
After registering for the first time, change the WPA preshared key to ensure that you

have a secure connection.
