I have a computer with Internet connection via Ethernet, it is Wi-fi capable so in order to share the Internet connection I had set up an ad-hoc network.
It works fine with other computers, but if only my iPad is connected, the link breaks whenever mi iPad is sleeping.
When turning on my iPad, I have to reset the ad-hoc network in the computer in order to have Internet available in my iPad again.
I wonder why it happens. Thanks.
