1. Cool Down and Restart the Router/Modem

If your Wi-Fi is running at low speed, you should consider turning the router/modem off and letting them cool down for a while before restarting them again. This is recommended especially for those who keep these two devices running all the time but don’t have the habit of turning them off once in a while. If they keep running in extreme heat, chances are you won’t have a stable Wi-Fi connection.

2. Toggle Airplane Mode On and Off

If you're using the cellular but the phone Internet is too slow to even load a picture, seeking help from toggling airplane mode on and off might work. However, every time you do so, please give it time to search for a better signal. And if it doesn’t work, try 3-4 times and wait patiently for it to respond.

3. Turn Off Background App Refresh

If this feature is enabled, it means your iPhone will keep updating the latest content under Wi-Fi or cellular connection. If it goes on for a long time, your iPhone may be packed with tons of information, which cause it unable to run smoothly for the lack of enough storage space, thus preventing the network to run at a normal speed. Therefore, it’s necessary for you to turn off this feature to release certain storage.

Go to Settings>General>Background App Refresh>Toggle off the button next to it.
