Configuration and Management
2.6.7.1 None
If you select “None” 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 W21 at any time and
having access to both your home network and Internet connection.
2.6.7.2 WEP and WEP Encryption Key
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 device on your WLAN has
to be manually configured with the same key as the Ericsson W21 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 Apply to
save the settings.
2.6.7.3 WPA/WPA2 and Passphrase
WPA (Wi-Fi Protected Access) and its successor WPA2 are the most
reliable security options. WPA encryption uses the TKIP (Temporal Key
Integrity Protocol) while WPA2 encryption follows AES (Advanced
Encryption Standard). AES offers a higher level of security and is approved
for sensitive corporate and government data transmission.
WPA and WPA2 authentication and encryption require a passphrase. A
passphrase is a sequence of words or other text and is similar to a
password in usage, but is generally longer for added security.
Each device on your wireless network has to be configured with exactly the
same passphrase as the Ericsson W21 in order to allow encrypted data
transmission.
A WPA or WPA2 passphrase is case sensitive (distinguish between
uppercase and lowercase letters) and consists of between 8 and 63
