I always lurk on these computer-help threads because they're so informative and downright useful. But this is my first request. My dear lady friend drives long-haul OTR and wanted me to help her with using a laptop logged on the net and without trailing a 3,000 mile cable.So we got a new lap top (a Dell that comes with a "wireless" card.)The question is: What do we need to do to enable (what kind of) wireless link from a mobile (tractor-trailer or a boat/ship) unit to the internet?
