my main computer is desktop windows xp set up the router to the lan modem. trying to password protect from my g4 ibook ,( although my internet signal is pretty strong ) contacted Linkseye with no response after acknowledging my inquiry. someone suggested: Connect the iBook to the internet and then go to sharing in system preferences, click the internet tab, make sure airport is checked then click start. Airport options lets you make a WEP key to make the network secure. when I tried this on my ibook it said that It could effect my isp settings and violate the lan agreement with my cable company , your thoughts please.
