  WPA/WAPI Encryption –  selects a WPA/WAPI data  encryption method: TKIP+AES, 
AES: 
–  TKIP  –  the  encryption  protocol  used  for  WPA.  It  implements  a  more 
efficient mechanism of key change management in comparison with WEP; 
–  AES  –  an  algorithm  of  128-bit  clock  encryption  with  a  key  of 
128/192/256 bits that is generally used for WPA2;  
Make sure that PC's wireless adapter supports the selected encryption type. 
 
The most  secure  protection of a wireless channel is reached by  joint  operation of  access point and 
RAIUS server (for authentication of wireless clients). 
— WEP Encryption – select Enable in the drop down list to enable WEP encryption; 
—  Encryption Strength – 64- or 128-bit key encryption; 
—  Current Network Key – the key that will be used for connection; 
—  Network  Key  1..4  –  allows  specification  of  4  different  keys,  which  comprise  of  10  hex 
characters of 5 ASCII characters

 for 64-bit encryption. Other options are 26 hex characters or 
13 ASCII characters for 128-bit encryption.

4.5.3  The MAC Filter Submenu. Filtering Settings of MAC Addresses 
The menu allows filters configuration for MAC addresses. 
 
–  Select SSID – the identifier of the wireless network, for which a rule will be created; 
–  MAC Restrict Mode – filtration mode for MAC addresses:  
–  Disabled – filter is disabled; 
–  Allow – filters allowed addresses; 
–  Deny – filters denied addresses. 
In  order  to  add  a  MAC  address  to  the  filtration  table,  click  Add  and  enter  the  address  into  the  MAC
