iPhone 11 Pro Max Slow Internet? Here’s How to Fix It

by

If your iPhone 11 Pro Max is loading websites painfully slow or taking forever to stream, you’re not alone. Slow internet browsing on an iPhone usually stems from software glitches, network issues, or simply an overloaded connection. Whether you’re using Wi-Fi or cellular data, there are proven steps you can take to speed things up.

Here’s how to fix slow internet on your iPhone 11 Pro Max.

1. Reboot Your Wi-Fi Router

Before diving into your iPhone settings, start with the basics — your router.

  1. Press the power button on your modem or router to turn it off.
  2. Unplug it from the wall and wait 30 seconds.
  3. Plug it back in and turn it on.
  4. Wait for all lights to become stable (especially the Wi-Fi or Internet light).

Once it’s back online, let your iPhone reconnect and test your browsing speed again using speedtest.net.

2. Restart Your iPhone

A quick reboot often solves weird bugs and laggy performance.

  1. Press and hold the Side button and Volume Up button together.
  2. Drag the power off slider to turn off your phone.
  3. After 30 seconds, press the Side button again to turn it back on.

Test your browser after the restart and see if your speed improves.

3. Clear Safari (or Browser) Cache and Website Data

Too much old cache can slow down your browser.

If you’re using Safari:

  1. Go to Settings > Safari.
  2. Scroll down and tap Advanced.
  3. Tap Website Data.
  4. Tap Remove All Website Data.

For Chrome or Firefox, clear cache from the in-app settings.

4. Forget and Reconnect to Wi-Fi

A corrupted Wi-Fi profile can mess with speed.

  1. Go to Settings > Wi-Fi.
  2. Tap the “i” next to your current network.
  3. Tap Forget This Network > Confirm.
  4. Reboot your iPhone.
  5. Reconnect to your Wi-Fi and re-enter the password.

5. Update iOS to the Latest Version

Apple often releases bug fixes that include improvements to connectivity.

  1. Go to Settings > General > Software Update.
  2. If an update is available, tap Download and Install.
  3. Make sure you’re connected to Wi-Fi and have enough battery or plug into a charger.

If your connection is too slow for wireless updates, update using a computer via iTunes or Finder.

6. Reset Network Settings

If misconfigured settings are causing issues, this will reset all network-related features to factory defaults.

⚠️ You’ll need to re-enter Wi-Fi passwords afterwards.

  1. Go to Settings > General > Transfer or Reset iPhone.
  2. Tap Reset > Reset Network Settings.
  3. Enter your passcode and confirm.

After your phone restarts, reconnect to your network and retest.

Using Cellular Data Instead of Wi-Fi?

Make sure:

  • You have sufficient data balance or allowance.
  • Signal strength is strong (avoid using data in low-signal zones).
  • Low Data Mode is turned off:
    Settings > Cellular > Cellular Data Options > Low Data Mode (turn this off).

Still Experiencing Slow Internet?

If none of the above helps:

  • Try using your iPhone on a different Wi-Fi network. If it’s faster there, the problem is likely with your home internet.
  • Contact your internet service provider to check for outages or request a modem/router reprovision.
  • You can also try a factory reset as a last resort — but only if you’ve backed up your device.
