2. Check for iOS Updates

You should also check for the available software updates on your iPhone. Even if you’re running on the latest iOS 17 version, Apple releases monthly patch updates or new build version updates for its iOS. Installing the latest update should fix multiple bugs or slow internet issues. To do so:

• Go to the Settings app on your iPhone > Tap on General.

  • If there is no update available, you’ll see the iOS is up-to-date notification on the screen.

3. Power Cycle the Wi-Fi Router

Sometimes only rebooting the game or device or switching the internet connection may not be useful because there might be an issue with the Wi-Fi router. In that scenario, performing the power cycle on your Wi-Fi router can also fix the internet connectivity-related issues completely. To do that:

• Turn off the Wi-Fi Router first > Once the LED indicators stop, unplug the power cable from the router.
• Now, wait for around 30 seconds, and then plug back the power cable into the router.
• Turn on the router to check for the issue.

4. Check Your Internet Connection

The chances are also high that somehow your internet connection becomes poor or unstable and your iPhone can’t download or update. Cross-check with the internet connection no matter whether you’re using mobile data or Wi-Fi. In case, you’re facing any app-related issues such as the app not downloading or being unable to update then you should ensure your internet connection is running well. Try using any other Wi-Fi network or mobile hotspot to check for the issue.

5. Turn On Airplane Mode and Turn It Off

• Open the Settings app > Tap on Airplane Mode.
• Make sure to Turn On the toggle and wait for a few seconds.

7. Ensure Your Internet Data Limit is Available

It’s also worth mentioning to check whether your internet data limit is still under control or not. If the data limit has expired for the day or for the month then wait for the next data cycle. Otherwise, try recharging the additional data limit to the existing plan to be able to use the internet again.

10. Disable Wi-Fi Assist

11. Enable Data Roaming
