Power Management—The Power Save option is designed to conserve your computer’s battery life. If you click the Power Save, your wireless LAN Card will go into sleep mode, minimizing power consumption.
Note: If you enable power saving, the Access Points you use need to support power saving as well—otherwise communication cannot be established.
RTS Threshold—RTS Threshold is intended to prevent the problem of “Hidden Nodes.” Hidden Nodes involve two stations that are within range of the same Access Point, but are not within range of each other—they cannot hear each other. When one station begins transmitting data via the Access Point, it might not notice that the other station is already active. When these two stations send data at the same time, they may collide when arriving at the Access Point. Such collisions result in a loss of messages for both stations.
Click Enable to use RTS Threshold on a suspect hidden station. The station and its Access Point will then use a Request to Send/Clear to Send protocol (RTS/CTS). The station will send an RTS to the Access Point, informing that it is going to transmit data. On receipt, the Access Point responds with a CTS message to all stations within range, notifying them to defer transmission.
