Authentication RADIUS Server: RADIUS is an authentication,
authorization and accounting client-server protocol. The client is a Network
Access Server that desires to authenticate its links. The server is a server that
has access to a user database with authentication information.

default is 1812.
IP Address: Enter the RADIUS Server’s IP Address provided by your ISP.
Password: Enter the password that the AP shares with the RADIUS Server.

Fragment Threshold: Fragmentation mechanism is used for improving the
efficiency when high traffic flows along in the wireless network. If your
802.11g Wireless LAN PC Card often transmit large files in wireless
network, you can enter new Fragment Threshold value to split the packet.
The value can be set from 256 to 2346. The default value is 2346.
RTS Threshold: RTS Threshold is a mechanism implemented to prevent the
“Hidden Node” problem. “Hidden Node” is a situation in which two
stations are within range of the same Access Point, but are not within range
of each other. Therefore, they are hidden nodes for each other. When a
station starts data transmission with the Access Point, it might not notice that
the other station is already using the wireless medium. When these two
stations send data at the same time, they might collide when arriving
simultaneously at the Access Point. The collision will most certainly result
in a loss of messages for both stations.
Thus, the RTS Threshold mechanism provides a solution to prevent data
collisions. When you enable RTS Threshold on a suspect “hidden station”,
this station and its Access Point will use a Request to Send (RTS). The
station will send an RTS to the Access Point, informing that it is going to
transmit the data. Upon receipt, the Access Point will respond with a CTS
message to all station within its range to notify all other stations to defer
transmission. It will also confirm the requestor station that the Access Point
has reserved it for the time-frame of the requested transmission.
