If an iPhone 11, 11 Pro or 11 Pro Max cannot join Wi-Fi, Apple's order is: open Settings, Wi-Fi and make sure it is on, join the network and look for the blue checkmark, confirm Airplane Mode is off, check that Connectivity Assist is off, then restart the phone. If the network does not appear, it may be hidden or not meet Apple's router recommendations. Wikipedia lists Wi-Fi 6 (802.11ax) for the iPhone 11, so all three phones can use a modern router; a message that says No Internet Connection usually points at the router or your provider, not the phone.

Model-specific
What is true of this model and not of its siblings

- Tools and supplies
- Your router's admin page or app, your Wi-Fi password and a second device for comparison. A dry towel keeps the phone clean while testing.
- Repair cost

Exact questions
Common questions
Does the 11 Pro connect differently from the iPhone 11?+
No. Apple's Wi-Fi article is the same for every iPhone, and the 11, 11 Pro and 11 Pro Max share the A13 Bionic chip and the same Wi-Fi hardware family per Wikipedia.
Does the iPhone 11 support Wi-Fi 6?+
Yes. Wikipedia lists Wi-Fi 6 (802.11ax) for the iPhone 11, so it can join a Wi-Fi 6 router, and Apple's Wi-Fi article is the same for every iPhone.
Should I forget the network and rejoin it?+
Apple's steps start with the Wi-Fi setting and the network name; if the phone still cannot join, forgetting the network and entering the password again is a low-risk step before resetting network settings.
What does the blue checkmark mean?+
Apple says a blue checkmark beside the network name in Settings, Wi-Fi confirms the phone is connected to it. No checkmark means you have not joined yet.
How do I know whether the router is at fault?+
Apple says to check whether other devices can connect. If they can, the router and network are working and the phone is the likelier cause; if none can, restart the router or contact your provider.
Why is my network missing?+
Apple says the network might be hidden by technology that blocks unauthorized devices, or it does not meet Apple's recommendations.
Will resetting network settings erase my photos?+
No. It removes saved networks, cellular settings and VPN settings, not your photos or apps.
Can a VPN stop Wi-Fi working?+
Yes. Apple says to uninstall VPN and security software as a test.
Could a battery swap fix Wi-Fi?+
No. Wi-Fi is a separate part. At $89 the battery repair does not change it.
What if only one network fails?+
Then the network is the likelier cause; try another network and contact your provider.
