Hello, here are some potentially useful ways to fix the iPhone 11's slow wireless network:
1. Make sure your iPhone 11 is connected to a stable Wi-Fi network, not a crowded one.
2. Restart your iPhone 11 and Wi-Fi router. This helps refresh the network connection and may increase wireless speed.
3. Try disconnecting your iPhone 11 from the Wi-Fi network and reconnecting it. This helps clear up any possible connection issues.
4. Make sure you have the latest iOS version on your iPhone 11 and try to update it.
5. Disable Wi-Fi Assist. This feature may switch to cellular data when your Wi-Fi signal is weak, resulting in slower speeds.
6. Clear your iPhone 11's network Settings. This will delete your Wi-Fi network and password and restore your network Settings to factory Settings.
7. Contact your Internet service provider for assistance. If your wireless speed is still slow, it may be because your Internet connection is slow or there is a problem.
