Switching from wifi to cellular after update

I have an iphone15 pro max with AT&T. I updated to ios 18.3. Now when I am at home it keeps switching between wifi and cellular every few seconds. I Tried turning off wifi assist but still does the same thing.

iPhone does not switch automatically from wifi to cellular internet Hi, I just upgraded to the iPhone 14 Pro from the iPhone 12 Pro. I am having trouble with my cellular internet on the new iPhone 14 Pro. The iPhone does not switch automatically from wifi to cellular internet. When I leave the wifi range, I have to restart my iPhone to get cellular internet to start working. Needless to say, this is very annoying to restart my iPhone all of the time. Any recommendations?

If you connect to Wifi, doesn't necessarily mean you are connected to the internet. --> Internet not available WiFi and Cellular … - Apple Community

Wi-Fi Assist is on by default. This will automatically switch to Cellular Data if the device is not connected to the internet.
