iPhone 11 Pro Max internet dropping out when using apps

Hi coffee-bean-7,

Thanks for using Apple Support Communities! If I'm understanding correctly, your iPhone 11 Pro Max is not providing an internet connection when using your home Wi-Fi, and I'd like to help out.

You mentioned resetting the internet, did you mean resetting network settings on your iPhone? Here are the steps to verify that reset was done:

Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you’ve used before.

After that reset, reconnect to your Wi-Fi network, and test to see if you can use the internet.

If not able to, are you able to connect to a different Wi-Fi network and use the internet? Try to avoid using a captive Wi-Fi network, where you sign in on a web page, such as in a hotel, school, airport or coffee shop.

If you can successfully use the internet with a different Wi-Fi network, you'll want to see if there is a firmware update for your Wi-Fi router. Check with your router manufacturer, if you're not sure how to check for that. Especially if your iPad is not also on iOS 13.2.3.

If you're not able to connect and use the internet with any Wi-Fi network, you should have your iPhone examined by a technician.
