The last few gigs, my iPad air has been re-syncing litterally every minute while performing. I keep it mounted to my mic stand right in front of me and it's to the point I'm going to call tech support. I just checked and 'Ask to join networks' was on so I flipped it off. A number of times I needed to make an volume adjustment and I had to access MF on my phone as the ipad would take forever to re-sync. Im up to date software wise using MF4 and my Apple airport express which is a couple of years old. Any one want to chime in with ideas?
That was happening to me, as well, and I found a trick to fix it. I turned off WiFi on my iPad, then turned it back on again, and connected to the router. It worked just fine after that. I've had to do this on more than one occasion.
