Which authentication and encryption method that should be used depends
on what is supported by the connected wireless client(s).
Note: Each wireless client must be configured to use exactly the same
security mode and key/passphrase as the Ericsson W3x or they will
not be able to connect.
In the “Authentication” drop-down list you select which type of
authentication/encryption you want to use for your WLAN. The following
subsections describe the authentication methods supported by the Ericsson
W3x.
3.6.8.1
Open (No security)
If you select “Open” as authentication method no client configuration is
needed but be aware of that the WLAN will now be open without any kind
of security. For example, it is now possible for anyone with a computer and
a wireless interface card to connect to the Ericsson W3x at any time and
having access to both your home network and Internet connection.
3.6.8.2
WEP and WEP Encryption Key (Low security)
WEP (Wired Equivalent Privacy) is considered to be a low security option.
The data is encrypted into blocks of either 64 bits length or 128 bits length.
WEP encrypted data can only be sent and received by users with access to
a private encryption key. This means that each client on your wireless
network has to be manually configured with exactly the same key as the
one entered in the Ericsson W3x in order to allow encrypted data
transmissions.
• WEP-64 bit data encryption requires a key including 10 characters.
Only hexadecimal numbers 0-9 and letters a-f (uppercase or
lowercase) are allowed.
• WEP-128 bit data encryption requires a key including 26 characters.
Only hexadecimal numbers 0-9 and letters a-f (uppercase or
lowercase) are allowed.
Enter an encryption key in the “Passphrase / Key” field and click

to
save the settings.
3.6.8.3
WPA/WPA2 and Passphrase (High security)
WPA (Wi-Fi Protected Access) and its successor WPA2 are the most
reliable security options. WPA encryption uses the TKIP (Temporal Key
