I'm trying to get internet on my iphone via my home adsl connection. I've got a standard adsl modem (no router) with a direct ethernet connection to my imac (early 2009 model) running 10.6.8. I thought the process would simply be to turn on internet sharing in system prefs and set a network. Since the imac has airport extreme built in. The iphone see's the network but can't connect. I just get the spinning circle animation. Can anyone help sort this out?
