A method and system for conserving battery strength of a client device, such as a laptop computer, on a wireless local area network (WLAN). The client device monitors the addresses of incoming data packet messages while running at a lowest bandwidth permitted by the protocol of the client device. When a data packet is detected that is addressed to the client device, the client device bandwidth is increased to a higher bandwidth to receive subsequent data packets. Subsequent incoming data packets are received by the client device until transmissions cease, after which the client device returns to the lowest bandwidth. By remaining in a lowest bandwidth mode while monitoring incoming packets, the client device is able to extend the life of the client device battery.
