Just bought a Deco X4300 Pro (3 decos), set up was easy, the app works great.  I used Netgear before and no issues, but wanted to try Tp Link.  Unfurtunately, I did not read enought and was not aware these units have issues with IOS devises.  They many other issues like suddenly disconections, etc.  But I am more concern about solving the iPhones and iPads loosing wifi connections.  I have tried many solutions from the forums, but still no solving the problem.  Can someone advise if there is a definitive solution?  Firmware up to date, if an IT person is on this forum, please help
