iPhone Wi-Fi Runs Slowly? How To Fix?

The iPhone has faced connectivity issues, particularly with the iPhone XS Max model, where users reported experiencing poor signal and network connection problems. In an effort to rectify these concerns, Apple rolled out the iOS 12.1 update. Despite this, some iPhones may continue to encounter intermittent Wi-Fi connections and sluggish network speeds, even when other devices operate without issue. To tackle this, here are nine effective solutions to resolve the intermittent and slow Wi-Fi issues on your iPhone.

How to Improve Wi-Fi Signal and Internet Speed

Method 1. Restart the router

As mobile phones and operating systems receive constant upgrades, older routers might not keep up due to hardware limitations. Should you encounter weak Wi-Fi signals or slow speeds, it’s important to check your router to rule out external issues. To restart your router, press the power switch or reset button. Keep in mind that restart procedures can differ across brands; it is advisable to refer to your router’s manual for specific instructions. In cases where the router is the source of the problem, you may need to look into repairs or a replacement.

Method 2: Airplane mode reset method

Airplane mode can make the phone reset the network, recheck the network and try to connect, this method is suitable for sudden network failures. When we feel that the internet speed is a bit slow, we can turn on the airplane mode of the iPhone, wait for 10 seconds and then turn off the airplane mode, and then we test the internet speed to see if it is normal.

Method 3: Forget the Wi-Fi network and join it again

Method 6. Force restart iPhone

· If you have an iPhone 7 or iPhone 7 Plus, press and hold the Sleep/Wake button and the Volume Down button at the same time until you see the Apple logo appear on the screen.
