Our wifi connection has been very difficult to use with Iphones.
Every other internet hardware (laptop, android phones, android pads etc) works fine with no outage.
Constant ping tests show the connection all over the place (see picture). Some of the time it is perfect with expected returns other times it varies between timed out of extremely long ping time returns. If you leave a ping going it will eventually after several minutes return back to normal but then not long after go back to no returns or long returns.
I have tried everything resetting, changing settings on the Iphone, etc just cannot get it sorted.
Iphone pings
Laptop pings exactly same time.
