1 Check your Wi-Fi Router

If you are experiencing iOS 17/18 Wi-Fi not working problem, the first thing you need to check is your Wi-Fi router. If the router is too hot to withstand, then it's likely that the router is not stable enough for you to establish a Wi-Fi connection. Also, if the light on it won't flash as normal, it means your Wi-Fi is disconnected. Check the cable and make sure that it's firmly connected to the socket.

2 Toggle Wi-Fi Off & On

If the router is 100% not problematic, you can switch off the Wi-Fi on your iPhone and then turn it on to identify whether the problem of the iPhone not connecting to Wi-Fi can be solved. Also, you can turn to Cellular and see if the signal is stable. If not, you can seek other spacious places before trying these methods. Follow the given instructions.

• 1. Open the Settings app on your iOS device find the Wi-Fi option and turn off it.
• 2. Tap the switch to restart the Wi-Fi after waiting for 30 seconds. Now, join your Wi-Fi network using your iPhone.

You can try to connect your iPhone to another Wi-Fi network, if one is available, see if the issue is with the network or your iPhone.

3 Toggle On & Off Airplane Mode

If your iPhone not connecting to Wi-Fi because your iPhone not accepting Wi-Fi password, it's also advised to restart the network by first activating airplane mode on your iPhone and then disabling it. Though it's quite simple and works for some people, it can easily fail. If this happens, you can try 4-5 times and give it enough time to search and retrieve the signal for your iPhone. To do this, take the following actions:

• 1. Swipe down from the top of your screen (For iPhone with the Home button, this should be seen by bringing up the control center from the bottom of your screen).
• 2. Tap the airplane icon to turn it on and stay still for 15 seconds or so, then tap it again to turn it off, and don't connect your iPhone until it fully obtains the signal.

4 Disable the VPN

If you have the habit of turning on the VPN all the time, it's time to give it a break since it may interrupt your device and that's why your iPhone won't connect to Wi-Fi. Switch the VPN off for a few minutes, or you can log into the router's admin dashboard and then switch it off from there to deactivate the VPN. If this is not the solution you're looking for, please keep reading.

• 1. On your iPhone, open the Settings app and select Wi-Fi.
• 2. From the list, tap the name of the Wi-Fi network. Then click the "i" next to it. Then click Forget This Network.
• 3. Wait for a few minutes and once again connect it with the password.
