Quite often when I'm listening to my radio app it will stop working for no reason and all I get is the little circle thing rotating as it tries to reconnect. I then find if I try to open anything that needs a wifi connection it won't work, I.e. BBC iPlayer. I have to hard shut down the iPad and switch it back on and then I get connection back. This happens a lot and is really annoying. The wifi is definitely ok and if I go into Settings it says that wifi is connected. Is this a common problem and if so are Apple doing anything to rectify it.
