Abstract

A device and method support dialup modem access over a wireless local area and/or personal area network such as, for example, an IEEE 802.11 a/b/g/n and/or IEEE 802.15.3a network. A representative embodiment permits a user of a conventional Internet web browser application to access a dialup information provider via a switched telephone network, using the wireless network. A terminal adapter comprising a wired network interface and a wireless network interface receives messaging containing dialing information from a user of a personal computer, via the wireless network. The terminal adapter establishes a dialup connection to the information provider, and exchanges information between the personal computer and the information provider via the wired and wireless interfaces. Information used for dialing may be contained within a universal resource locator received by the terminal adapter, or may be received as a result of user input on a webpage type user interface displayed by the browser application using information sent by the terminal adapter.
