Hi all,
I like this program and I want to see it succeed. I was having grief, but the advice "Also, sometimes when the device has not been active on the network for a while the router may "forget" about it and the connection will fail. A suggestion to avoid this is to open the 'Settings' app on your iPhone/iPad, turn off wifi and then turn it back on to join the network again. This will help making sure that the connection with the router is established." worked for me.
