I found a thread from last year where other people were having a problem I’m having. My Wi-Fi at home is working great on all other devices but on my iPhone XS max, It is constantly disconnecting. I have tried all of the fixes suggested including turning Wi-Fi on and off, Turning the phone on and off, are you studying network settings, for getting the network and reconnecting, airplane mode. Has anybody found a fix?
iPhone XS Max, iOS 12
If you already tried also resetting network settings to no avail, AND if your iphone does the same thing when connected to different wifi networks, it could be a hardware problem. Since the device is still covered by warranty, have it inspected at an Apple Store or Authorized Service Provider: https://locate.apple.com/findlocations
Shouldn’t be this case (your iphone has that behavior at home only), It could be a modem router wrong setting. Check it.
