use by the wireless client that is attempting to make a connection.
• a e s - 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.

This field is available only when you select wpa 2 in the Se c urity Mo d e field and set Ciphe r
Type to a e s.
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 O p tio na l if you do not require the wireless clients to support MFP. Management
frames will be encrypted if the clients support MFP.
Select Re q uire d and wireless clients must support MFP in order to join the Zyxel Device’s
wireless network.
OK Click O K to save your changes back to the Zyxel Device.
Cancel Click C a nc e l to exit this screen without saving your changes.
