Hmm that may mean you have a firewall or some other seruticy software preventing data from getting through. You could try disabling stuff like that on your router and see if that helps. Another thing worth trying is creating a network directly on your mac ( Create Network under the airport menu) and connecting your iOS device directly to that. It's kind of tedious, but one upside is that data will be going straight to your Mac so your latency should be really low.
