If your iPhone 6s suddenly can’t connect to Wi-Fi after installing iOS 9.3.2, you’re definitely not alone. Some users also reported getting hit with the dreaded Error 56, which can even brick the device. Before you panic or rush to the Apple Store, there are a few things you can try yourself to fix the problem.

Here’s exactly what to do.

Why Wi-Fi Problems Happen After Updates

Even though updates are supposed to fix bugs and improve performance, they can sometimes mess with your settings. Some common reasons why your iPhone can’t connect to Wi-Fi after an update include:

Network settings reset automatically.
Third-party apps interfering with Wi-Fi connections.
Issues with your wireless router (outdated firmware, bad connection).
Hardware issues triggered by a botched update.

6 Ways to Fix iPhone 6s Wi-Fi Problems After iOS 9.3.2

1. Reboot Your iPhone

Sometimes a simple restart can clear out update-related glitches.

How to restart:

Hold the Power button until “slide to power off” appears.
Slide to turn off your phone.
After 30 seconds, press and hold the Power button again to turn it back on.

2. Check and Reset Your Wi-Fi Settings

Make sure Wi-Fi is actually turned on and you’re connected to the correct network.

Steps to check Wi-Fi:

Open Settings > Wi-Fi.
Make sure Wi-Fi is toggled on.
Tap your network name and re-enter the password if necessary.
Look for the blue checkmark next to the network name—it means you’re connected.

3. Disable Third-Party Security Apps

If you have a third-party VPN or security app installed, it might be blocking Wi-Fi connections.
Temporarily disable or uninstall the app and see if that fixes the issue.

4. Restart Your Router and Modem

Sometimes the problem isn’t your iPhone—it’s the network itself.

How to restart your router/modem:

Power off both the router and modem.
Unplug them from the wall.
Wait 30 seconds.
Plug them back in and turn them on.

After your network is back up, reboot your iPhone and try reconnecting.

Also double-check that all cables are plugged in tightly!

5. Reset Network Settings on Your iPhone

If your Wi-Fi still isn’t working, reset all network settings.
(This erases saved Wi-Fi passwords and VPN settings, but it won’t delete your personal data.)

How to reset network settings:

Open Settings > General > Transfer or Reset iPhone > Reset.
Tap Reset Network Settings.

Your iPhone will reboot and you’ll need to reconnect to Wi-Fi manually.

6. Restore Your iPhone Using iTunes

If nothing else works, restoring your iPhone might clear up any deep-seated software problems.

Here’s how to do it:

Open iTunes (or Finder on macOS Catalina and newer).
Connect your iPhone to your computer with a Lightning cable.
Follow the prompts to Trust This Computer if needed.
Select your iPhone when it appears in iTunes/Finder.
Click Restore iPhone.

This will wipe your iPhone and reinstall a fresh version of iOS 9.3.2.
You can then either set it up as new or restore from a previous backup.

If Nothing Works…

If you still can’t connect to Wi-Fi or if you’re getting Error 56, it’s time to escalate:

Contact Apple Support or visit a Genius Bar.
Tell them you’ve already tried rebooting, resetting, and restoring—they’ll know you’re serious.

There’s a chance your iPhone needs a hardware repair or replacement if it was damaged during the update.
