In the method and apparatus for registering wireless terminals with an access point (AP) through a wireless network according to the present invention, there is no need for a re-registration procedure for terminals because, when the AP is restarted, the AP informs wireless terminals registered in its service area of the restart of the AP so as to allow each of the terminals to perform its own location registration. In addition, total update is possible, this method being in contrast to methods in which notification of a restart of the AP is carried out in a one-to-one manner using the broadcast data. As a result, efficiency in time and in the overall network is achieved by the invention. The AP can easily restore the address resolution protocol (ARP) table that has been cleared by the restart process because the terminals send the ARP table themselves, thereby providing for stabilized service.
