Key Length Select the bit-length of the encryption key to be used in WEP connections.
If you select WEP-64 :

0x11AA22BB33) for each Key used.
or
• Enter 5 ASCII characters (case sensitive) ranging from “a-z”, “A-Z” and “0-9” (for
example, MyKey) for each Key used.
If you select WEP-128 :
• Enter 26 hexadecimal digits in the range of “A-F”, “a-f” and “0-9” (for example,
0x00112233445566778899AABBCC) for each Key used.
or
• Enter 13 ASCII characters (case sensitive) ranging from “a-z”, “A-Z” and “0-9” (for
example, MyKey12345678) for each Key used.
Key 1~4 Based on your Key Length selection, enter the appropriate length hexadecimal or
ASCII key.
The following fields are available if you set Security Mode to wpa2 or wpa2-mix .
PSK Select this option to use a Pre-Shared Key with WPA encryption.
Pre-Shared Key Enter a pre-shared key of between 8 and 63 case-sensitive ASCII characters (including
spaces and symbols) or 64 hexadecimal characters.
Cipher Type Select an encryption cipher type from the list.
• auto - This automatically chooses the best available cipher based on the cipher in
use by the wireless client that is attempting to make a connection.
• tkip - This is the Temporal Key Integrity Protocol encryption method added later to
the WEP encryption protocol to further secure. Not all wireless clients may support
this.
• aes - This is the Advanced Encryption Standard encryption method. It is a more
recent development over TKIP and considerably more robust. Not all wireless clients
may support this.
Idle Timeout Enter the idle interval (in seconds) that a client can be idle before authentication is
discontinued.
Group Key Update
Timer Enter the interval (in seconds) at which the AP updates the group WPA encryption key.
Pre-Authentication This field is available only when you set Security Mode to wpa2 or wpa2-mix and
enable 802.1x authentication.
Enable or Disable pre-authentication to allow the AP to send authentication
information to other APs on the network, allowing connected wireless clients to switch
APs without having to re-authenticate their network connection.
