This is the 802.11b standard. Data is encrypted before transmission, but the
encryption system is not very strong.

WEP
Authentication Select Open System or Shared Key. All wireless
stations must use the same method.
Default Transmit Key Select a transmit key.
WEP Encryption Select an encryption option, and ensure your
wireless stations have the same setting:
64-Bit Encryption - Keys are 10 Hex characters.
128-Bit Encryption - Keys are 26 Hex characters.
Passphrase Generate a key or keys instead of entering them
directly. Enter a word or group of printable characters
in the Passphrase box and click the Generate button
to automatically configure the WEP key. It consists of
1 to 30 characters.
Key Value Enter a key in hexadecimal format.
Security Settings - WPA2-Personal
This is a further development of WPA-Personal, and offers even greater security.

WPA2-Personal
WPA Algorithm The encryption method is AES. Wireless stations must also
use AES.
Pre-shared Key Enter the key value. It is 8 to 63 ASCII characters or 64 HEX
characters. Other wireless stations must use the same key.
Key Renewal Specify the value of Group Key Renewal. It’s a value from
600 to 36000 and default is 3600 seconds.
WPA automatically changes secret keys after a certain
period of time. The group key interval is the period of time
in between automatic changes of the group key, which all
devices on the network share.
Constantly keying the group key protects your network
against intrusion, as the would-be intruder must cope with
an ever-changing secret key.
