reserved this block of addresses specifically for private use; please do not use any 
other number unless you are told otherwise. Let's say you select 192.168.1.0 as 
the network number; which covers 254 individual addresses, from 192.168.1.1 to 
192.168.1.254 (zero and 255 are reserved). In other words, the first three 
numbers specify the network number while the last number identifies an individual 
computer on that network.
Once you have decided on the network number, pick an IP address that is easy to 
remember, for instance, 192.168.1.2, for your device, but make sure that no other 
device on your network is using that IP address.
The subnet mask specifies the network number portion of an IP address. Your 
device will compute the subnet mask automatically based on the IP address that 
you entered. You don't need to change the subnet mask computed by the device 
unless you are instructed to do otherwise.
7.3.1  Administrator Authentication on RADIUS
The administrator authentication on RADIUS feature lets a (external or internal) 
RADIUS server authenticate management logins to the NWA. This is useful if you 
need to regularly change a password that you use to manage several NWAs. 
Activate administrator authentication on RADIUS in the SYSTEM > Password 
screen and configure the same user name, password and RADIUS server 
information on each NWA. Then, whenever you want to change the password, just 
change it on the RADIUS server.
