Anybus Wireless Bridge - Ethernet to WLAN

2.2.5 WLAN Security
The Wireless Bridge supports various authentication and encryption methods. The following authenti-
cation methods are supported:
Open connection
Shared secret
WPA and WPA2 Preshared key
•LEAP
•PEAP
The following encryption methods are supported:
No encryption
•WEP64
WEP128
•TKIP
AES/CCMP
The following table shows valid combinations of authentication and encryption methods (x means valid
configuration):
There are a few important considerations that also need to be addressed. If selecting WPA/WPA2 PSK
and TKIP, this is considered to be a WPA connection. If selecting WPA/WPA2 PSK and AES/CCMP,
a WPA2 connection is assumed. It is not possible to have WPA with AES/CCMP encryption.
To use LEAP or PEAP as the authentication algorithm, ensure that the access point supports this, as
not all do. Neither LEAP, PEAP nor WPA/WPA2 PSK will work in ad-hoc mode.
Note: Some access points have support for a combination of WPA and WPA2, as well as AES/CCMP
and TKIP. These options are not supported by the Wireless Bridge.
