When I checked the pictures you posted on page 26, and I noticed that your iphone is still on 3G cellular network. If the ad hoc works, you should see wi-fi sign on your iphone, and the special (don't know the name) sign on your Mac instead of wifi waves. Maybe something wrong when you tried to set the ad hoc?
Try delete whatever you made, restart both mac and iphone, and start all over.
I just tried deleted absolutely everything and starting from scratch for the third time. Nothing. I see the little "special sign" on the mac but 3G remains on the phone. The guy had the 3G sign on his phone when he got it working in the video so I dunno. Thanks for the suggestion though
I had the same problem you have but I tried this. Go to the Network Preferences page, then to TCP/IP and set Configure IPv6 to off. Make sure the subnet mask is manually set and matches that on the iPhone (mine is 255.255.0.0) and the IPv4 address is manually set to 13.37.13.38.
This worked for me. I'm posting this via tethering.![]()
This got me excited because when I came out of the advanced settings screen in network preferences, airport showed a green light and said it was connected (as opposed to the orange light and self-assigned IP). False hope however as when I went to open Safari it still didn't work.
I'm really not understanding what's going on and will take whatever help you all can offer. Thanks.
