• Interference avoidance (on / off, default: off): Enables a WLAN procedure to enhance
radio interference avoidance.
Security settings
These settings determine the encryption used for the WLAN connection. Select one of the
four modes (Open, WEP, WPA, or Radius). This will activate / gray-out the necessary
additional input fields that specify further security settings on the
WLAN profile page.
• Open system : Enable this option to deactivate authentication and encryption (“Internet
Café mode”). Note, that all data is transferred un-encrypted in this mode, which can be
easily eavesdropped with any WLAN equipment.
• Wired equivalent privacy (WEP) : Enable this option to use the older WEP encryption
mode. This mode may be useful, e.g. if your WLAN should support older WLAN clients
that do not implement the recommended WPA encryption.
-
Privacy (on / off, default: off): De-activate this setting to use no authentication (“Open
System”) with standard WEP encryption. Activate this setting to use an additional
shared key authentication between the RFP and the WLAN client.
- Number of tx keys (number, 1..4, default: 1): The WEP encryption can use a single
shared key or multiple shared keys (“key rotation”). Select the number of shared keys,
select how to enter a shared key (by default as
Text or as Hex value ), and select the
Cipher length (see Key settings below).
- Default tx key (number, 1..4, default: 1): If more than one shared keys is used, you can
select the default shared key. You need to configure the same default key on the WLAN
client.
- Key #1 – Key #4 : Enter one or more shared key. The Cipher length setting (see Key
settings below) determines the length of the required input. If you selected to enter as
Text (see above), input a password with 5, 13, or 29 characters that matches a 64, 128,
or 256 bit cipher. If you selected to enter as Hex value , you can input a hexadecimal
number with 10, 26, or 58 characters (0-9, a-f). Press the Generate button to generate
a random shared key that matches the current settings.
• WiFi protected access (WPA) : Enable this option to use the recommended WPA
encryption mode.
-
Type (selection, WPA any / WPA v.1 / WPA v.2, default: WPA any): Select the WPA
version required for WLAN clients. The WPA any setting allows WPA v.1 and WPA v.2
to be used concurrently. The WPA v.1 setting enforces the use of the older RC4-based
encryption. The WPA v.2 setting enforce the use of the stronger AES encryption. You
can also change the distribution interval (see Key settings below).
- 802.1x (Radius) : Select this option if your WLAN should use a RADIUS server for
WLAN client authentication (“Enterprise WPA” with different username/password
combinations per client). You also need to specify the Radius settings (see below). For
details about the RADIUS authentication procedure, using the public keys, and
importing certificates to the WLAN clients refer to the documentation of your RADIUS
server product.
- Pre-shared key : Select this option to use a single shared key for all WLAN clients
( Value setting below). A WLAN client user needs to enter the shared key in order to
connect.
