On this page you select an encryption procedure to secure your radio connections.

WEP Encryption

The WEP encryption standard is out of date. This setting provides only insufficient protection for your wireless connections. Even unauthorized persons can share your Internet access, monitor data and files you transmit and use shared printers in your network. Therefore we urgently recommend that you use secure WPA encryption if your WLAN devices support this standard.

  • WEP key length
    Select here the length of the key to be used as the WLAN key. Select the value "64 bits" only if the WLAN device you are using does not support any longer keys.
  • Decimal WLAN key
    Enter the network key in ASCII format in this field and click the "Generate Key" button to have a WLAN key generated. Define four WLAN keys and specify which is to be used for data encryption in the FRITZ!Box.
    There are two ways to enter the values for the keys in the fields "WLAN key 1" through "WLAN key 4":
    • Enter the WLAN keys in the WLAN key fields directly in hexadecimal format. For a key length of 64 bits, the WLAN key must be exactly 10 characters long. For a key length of 128 bits, the WLAN key must be exactly 26 characters long.
    • Have the program generate the values for the WLAN key fields.
      Proceed as follows to generate hexadecimal WLAN keys:
      1. Enter any word in the "Decimal WLAN key" field. The word may contain capitals and lower-case letters as well as numerals. The length of the word depends on the length you selected for the WEP key:
        64 bits: The key word must contain exactly 5 characters.
        128 bits: The key word must contain exactly 13 characters.
      2. Click the "Convert" button.

        3. The value entered in the "Decimal WLAN key" field is converted to a hexadecimal value and entered in the currently selected hexadecimal WLAN key field:

        5 characters: The WEP key is exactly 10 characters long in hexadecimal format.
        13 characters: The WEP key is exactly 26 characters long in hexadecimal format.
      3. Repeat steps "1" and "2" until a hexadecimal value is generated for each of the four WEP key fields.
      4. Once you have generated all four WLAN keys, select the radio network the four generated keys will use to protect the WLAN connection.

        All four WLAN keys must be made known in the WLAN settings of the WLAN devices. Define there which of the four keys is to be used to encrypt the data in the WLAN device.

  • Permit shared authentication in the network

    • Some WLAN devices request entry of the WLAN key even to register at the FRITZ!Box. Enable this setting to allow this kind of registration.

Click the "Apply" button to implement your changes to the settings.

Once you have clicked the "Apply" button, the "Settings for WLAN Security" window opens. All information required for the WLAN settings in the WLAN devices is summarized here. You can print out these settings.
