several intermediate rate steps between the maximum and minimum data rates. 
The IEEE 802.11g data rate and modulation are as follows:

Wireless security is vital to your network to protect wireless communication 
between wireless clients, access points and the wired network.

Wireless security methods available on the N4100 are data encryption, wireless 
client authentication, restricting access by device MAC address and hiding the 
N4100 identity.

The following figure shows the relative effectiveness of these wireless security 
methods available on your N4100.

Note: You must enable the same wireless security settings on the N4100 and on all 

wireless clients that you want to associate with it. 

In June 2001, the IEEE 802.1x standard was designed to extend the features of 
IEEE 802.11 to support extended authentication as well as providing additional
