I am designing a car computer that is a simple readout and data logger using an OBD cable. I want to avoid buying a screen, so I am planning to generate a wifi network using an AP dongle I have, and then VNC into the Pi using my iPad. However, when I connect to the wifi network with my iPad, it seems to disconnect after only a few seconds. I am thinking this is because the Pi is not providing any internet for the iPad. Is there a way to get around this?

In short, can I trick my iPad into thinking there is working internet using the raspberry pi?

    You need to be more specific. Not really sure what you are asking about? it is very confusing what you have wrote. Please try and re phrase the question or make a diagram so that we can understand you better. – Piotr Kula Sep 24 '13 at 15:52

    Could be a power issue. The pi is having to draw more power to usb to connect the iPad and cannot provide enough. I would suggest using a powered usb hub. – Jivings Sep 24 '13 at 19:32
  • @Jivings I don't have the ipad directly connect to the pi with usb. I want to connect it with wifi, but the iPad keeps disconnecting. – TheDoctor Sep 25 '13 at 2:21
  • IIRC, Apple devices have some sort of check to make sure they can contact apple or something when they connect to a WiFi network ? Maybe that's what's causing it ? Check the forums, they had a thread on apple devices a little while ago. – Lawrence Sep 25 '13 at 3:42

    @TheDoctor I realise that. When the iPad connects to the AP dongle wirelessly it will create more power draw on the Pi, causing it to kill the connection. – Jivings Sep 25 '13 at 7:48

There could be many things going wrong here, but this seems most likely to be a power issue to me, if USB dongle is draining too much power then the dongle will drop in and out every few seconds. Hope this helps.

    and so connecting the Wi-Fi dongle to the Pi via a powered USB hub would be the solution... – Greenonline Jul 16 '15 at 11:35
