iPhone switches from wifi to LTE

My iPhone SE (64 GB with 24.69 GB available) with iOS 12.1 has recently stopped holding the connection to my home wifi and switches to LTE. How can I resolve this?

I have Verizon wireless phone service. I have Comcast Xfinity internet service. My router is Apple Airport Time Machine.

iPhone SE, iOS 12.1

Hello Mary,

Thank you for reaching out in Apple Support Communities. I understand your iPhone is having trouble staying connected to your home Wi-Fi. One thing to test is if this is happening on other Wi-Fi connections as well. This will help you isolate the issue to either your phone or your home Wi-Fi. Regardless, there are a few steps you can take to help resolve the issue.

Make sure that your router is on and you're within range

If you're too far from your router, you can't get a signal, so make sure that you're within range.


Make sure that Wi-Fi is on and you can see your network

Tap Settings > Wi-Fi and make sure that Wi-Fi is on. Tap the name of your Wi-Fi network to join. A blue checkmark beside a network name means that you're connected.

If you see Auto Join Disabled under your Wi-Fi network name, tap it turn on Auto-Join.

If asked, enter your Wi-Fi password

If asked, enter the password for your Wi-Fi network. Get help if you don’t know your password.

Even if you enter the correct password, you might see an "unable to join the network" message or an "incorrect password" message. Restart all of your devices, then try to enter your password again.


Check for issues with your Wi-Fi network

If iOS detects an issue with your Wi-Fi connection, you might see a Wi-Fi recommendation under the name of the Wi-Fi network that you're connected to. For example, you might see the alert "No Internet Connection." To get more information, tap the Wi-Fi network.

Check your cables and connections

If you still can’t connect to your network or get online, make sure that your router is connected to the modem and turned on.


Restart

Try restarting your iOS device, router, and cable or DSL modem. To restart your router or modem, unplug it, then plug it back in.

After you restart each device, see if you fixed the issue.

Still can’t connect?

Reset your Network Settings. Tap 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.
