Q: "After updating my iPhone 15 to iOS 17, it won't connect to WiFi, which is a big hassle for me. Is anyone else experiencing the same iOS 17 WiFi issue on their iPhone 15? How do I fix it?"
Since the launch of iOS 17, some users have been experiencing the great features of the new system, but also complained about some issues on iOS 17, of which "WiFi not working" is the most frequently mentioned. If you are also suffering from this problem, this article may help you.
WiFi not working issues on iPhone include the device won't connect to WiFi, slow WiFi speed, and dropped connection. These issues are mainly caused due to bugs on iOS, they can randomly appear on any iOS system and iOS 17 is not an exception. Apart from that, software conflicts, corrupted routers, and malfunctioning or misconfigured devices can cause WiFi issues on iPhone.
The WiFi signal is also one of the influencing factors, users need to keep a certain distance from the WiFi router to be able to connect to the network, the router can't provide a stable connection if the distance is too far. It's simple, but many users ignore it.
Currently, Apple has not officially revealed the reason why the wifi is not working after updating the iPhone to iOS 17, despite the lack of specific details, we can still try to solve the problem by the following methods.
After you realize that your iPhone is not connecting to the WiFi network, you should first come to troubleshoot the router and damage issues. You can verify this by connecting other electronic devices to this WiFi and if they are experiencing the same problem, then the root cause of the problem could be the router.
Just like computers, your router can also die due to software errors or too much of its running memory being used up, causing the CPU to run down. In this case, you just need to reboot your router. For hardware damage to your router, you should take it to a repair store.
There could be another very unlucky situation where both your iOS and the original router are faulty. If you're still not sure if the router is causing the iOS 17 WiFi issues, then you can try switching the WiFi on your iPhone and try connecting again, if the WiFi isn't working on the iPhone but working on other devices, then your iOS seems to be faulty as well.
If you are having problems with your iPhone, such as not being able to connect to WiFi, iOS 17 standby mode not working, iPhone randomly restarts, etc., then rebooting the device may be a good way to fix the problem. Here are the steps to reboot different iPhone models.
iPhone X, 11, 12, 13, or later:
Step 1: Press and hold either the volume button and the side button until the power-off slider appears, then drag it to turn off your device.
Step 2: Press and hold the side button until you see the Apple logo to turn on the device.
iPhone 6, 7, 8, or SE (2nd or 3rd generation):
Step 1: Press and hold the side button and when the shutdown slider appears, drag it to turn off the device.
Step 2: Turn the device back on by pressing and holding the side button until the Apple logo appears.
iPhone SE (1st generation), 5, or earlier:
Step 1: Press and hold the top button until the Shutdown slider appears, and drag it to shut down the iPhone.
Step 2: To turn the device on, press and hold the top button until the Apple logo appears.
After updating iOS, restoring the network settings to their initial state may help resolve connectivity issues if the iPhone is experiencing any of the following.
1. Wifi is not working, not connecting, or disconnecting frequently.
2. Bluetooth doesn't work properly.
3. You can't make or receive calls.
4. The iPhone is showing an unstable signal or only SOS mode.
It is important to emphasize that resetting network settings is not the same as restoring factory settings. Resetting the network settings only clears data related to the Internet, local network, and paired devices, and does not delete any files and browsing history stored on the device.
Step 1: Open the "Settings" app and select "General".
Step 2: Scroll down and tap on the "Reset" option and on the "Reset" screen tap on "Reset Network Settings".
Step 3: Enter your iPhone password as required and click on "Reset Network Settings" again. Wait for a few moments and then you can reconnect to the WiFi network, now check if the iOS 17 issue on your iPhone has been resolved.
If all the above methods fail and the iPhone still can't connect to the wireless network stably, you can try to fix WiFi issues on iOS 17 by upgrading to iOS, it is a common measure.
