My WiFi is working sometimes after few minutes automatically off then can’t be able to turn until switched off the device

Hi there rhy_them,

Thanks for joining us in Apple Support Communities! We understand you're having difficulty maintaining a reliable Wi-Fi connection on your iPhone, and sometimes you're unable to turn Wi-Fi on in Settings. We're glad you're here, and we can provide some guidance.

To begin, we noticed that your iPhone is running an outdated software version. The latest iOS version available is iOS 15.2. You can check which version is installed by going to Settings > General > About. Learn more about updating your iPhone here:

Update your iPhone, iPad, or iPod touch

Next, you'll want to be sure you worked through all the suggested steps in the related article linked in blue at the top left corner of this page.

Let us know how it goes, and we'll take a closer look if needed.

Take care.
