Key Length

Select the bit-length of the encryption key to be used in WEP connections.

If you select WEP-64: 

• Enter 10 hexadecimal digits in the range of “A-F”, “a-f” and “0-9” (for example, 

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.

WPA2/WPA2-Mix Authentication Settings

PSK

This field is available when you select the wpa2, or wpa2-mix security mode.

Select this option to use a Pre-Shared Key with WPA2 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.

• 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 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 WPA2 encryption key.

Management 
Frame Protection

This field is available only when you select wpa2 in the Security Mode field and set Cipher 
Type to aes.

Data frames in 802.11 WLANs can be encrypted and authenticated with WEP, WPA or 
WPA2. But 802.11 management frames, such as beacon/probe response, association 
request, association response, de-authentication and disassociation are always 
unauthenticated and unencrypted. IEEE 802.11w Protected Management Frames allows 
APs to use the existing security mechanisms (encryption and authentication methods 
defined in IEEE 802.11i WPA/WPA2) to protect management frames. This helps prevent 
wireless DoS attacks.

Select the check box to enable management frame protection (MFP) to add security to 
802.11 management frames.

Select Optional if you do not require the wireless clients to support MFP. Management 
frames will be encrypted if the clients support MFP.

Select Required and wireless clients must support MFP in order to join the NWA/WAC’s 
wireless network.
