Abstract

A computer system that attempts to establish an alternative network link upon failing to establish a requested network link is described. The computer system may encounter conditions where access to numerous networks, in particular wireless networks, is not available. Rather than only providing an error message to the user upon a failed attempt to establish the requested network link, the computer system determines whether the user has designated an alternative network link in case the requested network link cannot be established, whereas the alternative network link is selected from the plurality of network links that the computer system is configured to support. If an alternative network link has been designated, the computer system attempts to establish the alternative network link. Hence, the user experience is made smooth and uneventful when the requested network link cannot be established.

Claims

1. A method of enabling a user of an electronic system to provide an alternative network link designation for network links supported by the electronic system, comprising the steps of:

a) configuring one of the network links as network link so that the electronic system can initiate and establish it when requested by an application or the user;

b) designating one or more alternative network link designations for the primary network link, wherein said alternative network link designations are selected from the network links supported by the electronic system; and

c) storing the network link and the alternative network link designations associated with the network link in the electronic system.

2. A method of enabling a user of an electronic system to provide an alternative network link designation for network links supported by the electronic system, comprising the steps of:

a) configuring one of the network links as network link so that the electronic system can initiate and establish it when requested by an application or the user;

b) designating one or more alternative network link designations for the primary network link by omitting one or more network links from the network links supported by the electronic system by the user; and

c) storing one or more sets of the network link and the alternative network link designations associated with the network link in the electronic system.
