I've found that Wifi does not work properly on the iPad mini w/ Retina display. Some background: I own three iPads (iPad mini w/ retina display, iPad mini, and iPad 3rd gen), an iPod touch 5th gen, and a Macbook Air, and use them all frequently with my portable Wifi router. None of them exhibit any Wifi problems whatsoever except for my iPad mini w/ Retina display. Here are the details: - In the middle of using Wifi with my portable Wifi router, the Wifi connection will abruptly drop, then reconnect. After the Wifi reconnects, it is no longer able to connect to the internet (even though Wifi itself is connected). - Once the iPad mini w/ retina display's Wifi gets into this state, the following may or may not restore WiFi temporarily: -- Restart the device -- Reset network settings -- ...yet, even if connectevitiy is restored, the problem will happen again within minutes. - When the iPad mini w/ retina display gets into this state, the Wifi on my iPod touch, other iPads, and on my Macbook Air continue to work perfectly fine, so I know the problem is not with my Wifi device or it's connection, but specifically with the iPad mini w/ Retina display. Note: The iPad mini w/ Retina display never has any issues with my home or work Wifi networks. The problem only happens when connected to my portable Wifi device. Yet, all of my other iOS devices and my MacBook Air work perfectly with my portable Wifi device, therefore I know the problem is not with the Wifi device, but with the iPad mini with Retina display. Solutions: - Resetting the iPad mini w/ retina display to factory settings does not solve the problem - Resetting network settings on the iPad mini w/ retina display does not solve the problem - I have even replaced my original iPad mini w/ Retina and got a new one. Yet, the new device exhibits the exact same behavior as the original device. So this was not simply a hardware problem with my original iPad mini w/ Retina display. Conclusion: - I know this is not a hardware problem (since it happened with both my original as well as replacement device). - I know this is not a problem with my pocket WiFi router, since it works perfectly with all of my other iOS devices and MacBook Air. - Therefore, this must be a software / firmware bug with the iPad mini w/ retina display. Apple will need to fix this in a future software update. Has anyone else seen this problem?
