I have three iPhones in front of me right now. 1) iPhone 6S, 2) iPhone X, 3) iPhone XS Max. All of them connected to the same Wifi at home. The first two NEVER drop Wifi connection when they go into Lock Mode, Screen Saver, Sleep mode etc. WiFi is always available regardless if I have a VPN connection or not. Therefore my Wifi Calling is always available as are apps like WhatsApp Web that are connected with the first two iPhones. I have no complaints and everything works as it should.
However, the iPhone XS Max, the newest of all my phones, will ALWAYS drop Wifi when it goes into Lock Mode, Screen Saver, Sleep mode etc. Hence, WIFI CALLING, WEB APPS - NOTHING WORKS!!! I have wasted over a week trying to trouble shoot this problem, searching online, reseting network settings, hard restart, soft restart, with VPN, without VPN - Nothing Works. It is very disappointing that the Apple Genius's here cannot confirm how to fix this error. I dont want my iPhone XS Max to reconnect to the WiFi a few seconds after I unlock it, I want to REMAIN connected just like my first two iPhones so that I may be able to use them all in the same way.
How do I get my iPhone XS Max NOT TO DROP THE WIFI CONNECTION SO IT WORKS (with regards to not dropping Wifi Connection) EXACTLY LIKE MY iPHONE 6S and MY iPHONE X?
I'm not the only one with this issue so kindly put forward the solution.
Thank you!
