For Access Points that support power save mode and for stations equipped with 
WLAN cards, enabling this mode can significantly reduce power consumption, 
which is particularly important if the host computer is operating on battery power. 
However, be aware that power save mode also results in lowered transmission and 
reception speed on the wireless LAN. 
 

Selecting the Ad Hoc Channel 

 
When communicating in AdHoc or Pseudo AdHoc mode, you must specify a 
channel  on which communications will take place. To specify a channel, click the 
up or down arrow at the right of the AdHoc Channel field until the channel you want 
to set appears, and then click the Apply button.    
 
This field is greyed in infrastructure mode because the Access Point automatically 
selects the channel.  
 
 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 

 

6.  Encryption Menu

 

 

The Encryption menu lets you enable encryption and set the encryption keys. To 
see  the available encryption methods, click the down arrow at the right of the 
Encryption {WEP} field. 
 
There are two encryption methods available. The IEEE 802.11 specification 
defines  Wired Equivalent Privacy (WEP) using a 64-bit key. This capability was 
extended by  the industry to allow a 128-bit key.  If you specify an encryption 
method, you will only be able to communicate with Access  Points and stations that 
use the same encryption method and keys.
