Apparatus and method for automatic configuration of a personal computer system when reconnected to a network
First Claim
1. A method of reconnecting a computer terminal which supports stored original settings for network connection to a data transmission network, the steps of the method comprising:
- storing an indicator in the computer terminal and the data transmission network whenever the computer terminal has been physically disconnected from the data transmission network;
determining upon reconnection of the computer terminal to the data transmission network and in response to the indicator that the computer terminal has been disconnected from the data transmission network, whether original settings stored on the computer terminal are valid for attaching to the network in the location where the computer terminal is being reconnected;
reconnecting the computer terminal using those original settings if the original settings for the computer terminal are valid for attachment to the data transmission network where the computer terminal is being reconnected; and
requesting, using a network protocol, a refresh of the original settings if the original settings on the computer terminal are not valid and reconnecting using such refreshed settings for connecting the computer terminal to the data transmission network whereby the computer terminal requests new settings on its own volition and stores the new settings on the computer terminal for connecting the computer terminal to the data transmission network where the computer terminal is being reconnected.

Abstract
A system and method for connecting a computer terminal (e.g., a personal computer) to a data transmission network with the appropriate settings for connection obtained from the network if the terminal has been moved and the settings are not appropriate for the new location. The system and method involve detecting that the terminal has been removed from the data transmission network, and, if the terminal has been moved, checking to determine whether the previous settings are appropriate for use in the new location. If the settings are appropriate, then the previous settings are used; if not, new settings for the terminal are obtained from the network, using a program such as the IBM'"'"'s Dynamic Host Connection Program (DHCP), with the details on the settings (or connection) maintained at both the network and the computer terminal and updated when a new or changed connection to the data transmission network is made.

3. A system for connecting a computer terminal to a data transmission network with valid settings for connection thereto, the system comprising:
-
a sensing module for determining when the computer terminal has been removed from the data transmission network;
a module responsive to the removal of the computer terminal from the network for generating and storing a signal that indicates which computer terminal has been removed from the network;
a module for determining when a computer terminal is reattached to the transmission network and for determining whether the stored settings for the computer terminal are valid for the connection of the terminal at its new location on the network; and
logic for testing if the settings are valid for the reconnection on the network, then using those settings if valid; and
upon detecting the settings are not valid, obtaining and storing new settings for connection of the computer terminal to the data transmission network at the new connection, whereby the act of requesting new settings is triggered by the computer terminal acting on its own volition only if the old settings are not valid for the new location of the computer terminal on the data transmission network.- View Dependent Claims (6, 7)
