iOS 8 Wi-Fi problems
WI-Fi problems on iPad Air, iPad mini with Retina display and iPhone 5S after upgrading to iOS 8.
Typical results from OOKLA Speedtest before upgrade: Ping 17 ms, Upload 21 Mbps, Download 4.4 Mbps
Typical results after upgrade: Ping 39 ms, Download 2.9 Mbps, Upload 0.47 Mbps
iPad 2 with iOS 7.1.2 get 15 Mbps download and 4.4 upload on the same network.
Resetting network settings on the iOS 8 devices did not improve the performance.
Changing band on the router from 2.4 GHz to 5 GHz did give me back the speed on all devices.
However the speed occasonally drops on the iOS 8 devices, and the signal strengt can go from full til lost connection without moving the devices.
Also sometimes the Wi-Fi SweetSpots app report 0 mbps when the signal strenght is indicated as full and then suddenly go up to around 58 Mbps again.
It is almost like the device is trying to use cellular network that I do not have on the iPads before it suddenly switches back to Wi-fi nettwork again.
I am thinking about going back to my iPad 2 with iOS 7.1.2 that is working perfectly until the Wi-Fi issues are resolved.
Any help will be very much appreciated!
