7/2/12 I've been having the issue of the "Turn on Internet Sharing" button not appearing when creating a new Ad Hoc network which I have just resolved. Happy to get back on the web, I created the network and turned on the internet sharing button from this computer, which is a Hp windows 7 and tried to connect the Dell windows vista computer, which is a room or two away to the ad hoc network. When I tried to do this however, the dell connected to the network without any issues, but would not connect to the internet. Any help?
7/3/12 I'll try system restoring the dell D:
