I'm having a strange issue. I have 1 5300 acting as the main router & 3 5300 nodes. The problem is all my other devices are working but the IOS devices seem to be connected but internet connectivity isn't working until I toggle either wifi or airplane mode. Is there a certain setting such as MMIO or Airtime fairness or anything in professional that doesn't work correctly with IOS devices. I have a ton of wifi devices and its only my IOS devices giving me problems.
