I recently updated my iPhone to iOS 16.3.1 and now my phone is continuously dropping it's wifi connection. I have done all the usual tests (check my wifi, restart my router, hard restart of the iPhone etc.) and am still continuing to have problems. Any suggestions on how to fix this would be great!
Hi bscurf,
Thank you for posting in Apple Support Communities. You've tried some great steps so far. If you haven't already, it would also be best to test with multiple networks. That will help to identify whether the issue is network related. Make sure you've tried all steps in If your iPhone or iPad won't connect to a Wi-Fi network - Apple Support which can help with most Wi-Fi issues. It sounds like you've tried some of them but for your convenience, we've included all below.
1 Make sure that your router is on and that you're within range
If you're too far from your Wi-Fi router, you can't get a signal, so make sure that you're within range.
2 Make sure that Wi-Fi is on and that you can see your network
Go to 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 Settings > Wi-Fi > [Your Network], tap the More Info button and then tap Auto-Join.
3 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.
4 Check for issues with your Wi-Fi network
If iOS or iPadOS 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.
5 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.
6 Restart
Restart your iOS or iPadOS device.
Restart your router and cable or DSL modem by unplugging the device and then plugging it back in.
After you restart each device, see if you fixed the issue.
7 Reset your network settings
If you're using iOS or iPadOS 15 or later, tap Settings > General > Transfer or Reset [Device] > Reset > Reset Network Settings.
If you're using iOS or iPadOS 14 or earlier, 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.
Take care.
