Troubleshooting an iPhone 11 with slow internet connection after updating iOS to the latest version
Performing the following procedures can help rule out software-related errors that might have affected your browsing speed and slowed down the internet connection on your phone. Aside from a post-update bug, other factors that you should rule out are random firmware crashes that slowed down the network system on your iOS device, incorrect network settings, corrupted Wi-Fi network in use, as well as complex network system errors. Each of these factors will be eliminated through these subsequent methods.
Don’t forget to test your internet speed after performing each solution to determine whether or not your internet speed is back to normal. You can use free platforms such as fast.com or speedtest.net to test your iPhone’s internet connection.
First solution: Restart your iPhone (soft reset).
Symptoms that suddenly arise from an update are usually due to some minor system flaws that can be addressed by a system reboot. Thus, performing a soft reset is the first recommended solution to try on. A soft reset can help fix various types of problems including post-update network symptoms. Just follow these steps if you haven’t yet restarted your iPhone 11:
- Press and hold both the Side and Volume Up buttons for a few seconds.
- Release both buttons when the Slide to Power off bar appears.
- Swipe or drag the bar to turn your device off.
- After about 30 seconds, press and hold the Side button and then release when the Apple logo appears.
When the reset if finished, allow your iPhone to re-establish Wi-Fi signal and then reconnects to Wi-Fi. When it’s connected, check your browsing speed to see if it has improved.

Second solution: Disconnect your iPhone from Wi-Fi internet reconnect.
Another possible method to fix slow browsing issues from an iOS update is to restart or refresh your iPhone’s wireless internet functions. There are several ways for this to be done. First and the usual method is through the Wi-Fi toggle. And here’s how you do it:
- Tap Settings from your Home screen.
- Select Wi-Fi.
- Tap the Wi-Fi switch to the OFF position.
- After about 30 seconds, tap the switch again to turn Wi-Fi back ON.
Forgetting the Wi-Fi network can also help fix the problem if the recent update ended up corrupting your Wi-Fi network and thereby caused your internet connection to become sluggish. This will delete the network and then disconnect your device from Wi-Fi. Just follow these steps:
- Go to Settings-> Wi-Fi and make sure that the Wi-Fi switch is enabled.
- Scroll down to the list of available Wi-Fi networks.
- Select your Wi-Fi network then tap the option to Forget this Network.
- If prompted, confirm that you want to forget your Wi-Fi network. After confirming, your network will be deleted from your device. Turn Wi-Fi off and then restart your iPhone.
- As soon as your phone boots up, head back to Settings-> Wi-Fi menu and enable Wi-Fi again.
- Wait for your Wi-Fi network to show up in the list then select it.
- Tap the option to Join or Connect.
Be sure to input the correct Wi-Fi password to successfully connect to the network.
Another tweak you can use is the so-called Airplane Mode trick. It works by simultaneously restarting your iPhone’s wireless features including Wi-Fi networks. Performing this trick can also help eliminate wireless connectivity issues inflicted by iOS bugs. Here’s how it’s done:
- From the Home screen, tap Settings.
- Select Airplane Mode.
- Toggle the Airplane Mode switch to turn the feature ON. Doing so disables your iPhone’s wireless radios and associated features like Wi-Fi and Bluetooth.
- While Airplane Mode is turned on, reboot or soft reset your iPhone to clear out network cache.
- After it reboots, go back to Settings-> Airplane Mode menu.
- Then toggle the Airplane Mode switch to turn it OFF again.
Wait for your phone to re-establish Wi-Fi signal. When the signal becomes stable, reconnect to your Wi-Fi network and then check your internet speed to see if the slow browsing problem is gone.

Third solution: Update carrier settings, if possible.
Network connectivity issues including slow browsing symptoms attributed to an iOS bug can also be resolved by installing carrier settings update on your iPhone. These updates are rolled out by your carrier separately. Similar to iOS updates, carrier updates also embed some dedicated patches to eliminate existing errors from the phone’s network system including post-update bugs that caused your internet to slow down. Just follow these steps to manually check and install carrier updates available for your iPhone 11 using iTunes. Your computer must also be connected to the internet to make the carrier update installation successful. Just follow these steps when everything is set:
- Connect your iPhone to the computer and then open iTunes. Be sure to use the latest version of iTunes app to avoid bumping into some system conflicts.
- Wait for your device to sync and back up with iTunes.
- Click to select your iPhone 11 when it appears in iTunes.
- Navigate to the Summary section and then hold down the Shift key on the keyboard and click Check for Update. Doing so will prompt iTunes to install an iOS image (*.ipsw).
- Change the file type to iPhone/iPad Carrier Configuration File (*.ipcc).
- Select the desired file and then follow the rest of the onscreen instructions to complete the process.
When the carrier update installation is complete, turn your iPhone off and then disconnect it from the computer.
Fourth solution: Reset network settings to fix your iPhone that has slow internet connection after updating iOS.
Performing a network settings reset may be necessary to eliminate complex errors from the phone’s network system after the iOS update. These errors might have ruined your phone’s wireless internet system and thus resulted in slow internet browsing problem. To reset network settings on your iPhone 11, simply follow these steps:
- From the Home screen, tap on Settings.
- Select General.
- Scroll down and tap on b.
- Tap Reset Network Settings from the given options.
- Enter your passcode if prompted to continue.
- Confirm action by tapping on Reset Network Settings again.
Wait for your iPhone to finish resetting the network settings. It will restart automatically when the reset is complete. By then you can start re-enabling Wi-Fi and reconnect to your Wi-Fi network to get back online.
Fifth solution: Factory reset your iPhone 11.
A factory reset is usually the last solution to try if none of the previous methods is able to fix the problem and that your iPhone 11 still has slow internet connection. What you’re dealing with could be due to some major system errors that require more advanced solutions to be resolved. But be sure to note though that a factory reset also wipes all your iPhone data. That said, creating a backup is highly recommended before you proceed. You can back up your iPhone data to iCloud or iTunes depending on how you’d wish to factory reset your iPhone. If you prefer a factory reset through settings, then you can back up your critical data to iCloud then follow these steps to factory reset your iPhone 11:
- From the Home screen, tap Settings.
- Select General.
- Scroll down and tap on Reset.
- Select the option to Erase all content and settings. This will erase everything from your iPhone system including all saved data on the internal memory.
- Enter your device passcode if prompted to continue.
- Then tap the option to confirm that you want to erase your device.
If you prefer to use iTunes to manually erase and restore factory default settings on your iPhone, then you can back up your iPhone data to iTunes instead.
Does your iPhone 11 still has slow internet connection?
Slow browsing issues that are not remedied by the given procedures are usually attributed to some network problems that aren’t rectifiable on your end. In some cases, a damaged modem or router in use is to blame. Random firmware crashes on the network equipment can also be the underlying cause of slow browsing issue. To clear this out, performing the so-called power cycle on the network equipment can help. If you can reach your network equipment (modem or router) right now, follow these steps to power cycle it:
- Turn off your modem/router by pressing its power button.
- While the device is powered off, unplug its AC adapter from the power source. Keep it that way for about 30 seconds to 1 minute.
- After the elapsed time, press the power button to turn it back on.
- Wait for all the light indicators to become stable.
For further assistance in performing more advanced internet problem solutions, you can contact your Internet service provider. If necessary, they can re-provision or reset your network equipment remotely. A modem or router reset is often needed to fix recurring internet issues attributed to a corrupted modem or wireless router.
You can also escalate the problem directly to Apple Support so that they can make necessary assessments to confirm whether or not the slow internet connection experienced by your iPhone 11 is inflicted by an iOS bug.
