Wireless Security Overview
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 N220 are data encryption, wireless
client authentication, restricting access by device MAC address and hiding the
N220 identity.
The following figure shows the relative effectiveness of these wireless security
methods available on your N220.
Note: You must enable the same wireless security settings on the N220 and on all
wireless clients that you want to associate with it.
