This isn't a problem with me setting up a wireless internet connection for the first time, I am just trying to re-establish it and am having difficulties. The situation is as follows. I have an Apple Extreme Base Station, ADSL modem, ethernet cables and an iBook. When I link up the modem correctly and connect to the internet using a cable between modem and iBook, all is well. However if I link the modem to the base station (with an ethernet cable) and then try to connect wirelessly I can't do it. Does anyone have any solutions?
