Chapter 7: Security settings

Standard WEP encryption

As standard, WEP128 encryption is activated for every unconfigured device.

The key consists of the first letter “L” followed 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 “00A0570FB9BF” thus has a standard WEP key of “L00A0570FB9BF”. This key is entered into the 'Private WEP settings' of the device for each logical WLAN network as 'Key 1'.

To use a WLAN adapter to establish a connection to a new LANCOM access point, the WEP128 encryption must be activated for the WLAN adapter and the standard 13-character WEP key entered.

ensure that you have a secure connection.

Note that a reset also causes the WLAN key settings to be lost from

the device and the standard WEP key comes into effect again. WLAN access can only work after a reset if the standard WEP key is programmed into the WLAN adapter as well.
