There are a few things that you can check although I suspect you've already done this:
Change the settings on your iOS device to "Local" to verify that you can get any data.
Change the settings on your iOS device to the trixology-test address to verify that you can get data over the Internet.
Inspect the router administration page to verify that a private fixed IP address is still assigned to your host computer.
Inspect the host computer Network settings panel to verify that the private fixed IP address is being used.
Inspect the router settings to verify that the port range 49250 to 49254 is assigned the the private fixed IP address.
Wave 3 stalks of daffodils over your iOS device and say "Spring to life and bring me data!" three times.
Okay, may the last suggestion is a little far out, but I hope it made you smile. A smile can help.
