There could be various reasons for iPhone Not Connecting to Wi-Fi, ranging from minor software glitches and network related problems to other issues.
Since the problem cannot be narrowed down to a single reason, any of the following troubleshooting steps might help in fixing the problem of iPhone not connecting to Wi-Fi network.
iPhone Can’t Connect to Wi-Fi
Before going ahead with the troubleshooting steps, make sure that your iPhone is not in Airplane mode. This is especially true, if you have been travelling and forgotten to disable Airplane mode.
Open Settings > make sure the toggle next to Airplane Mode is set to OFF position.
If this is not the case, you can move to other troubleshooting steps and hopefully make your iPhone connect to your home, office, or hotel’s Wi-Fi network.
1. Enable/Disable Wi-Fi
The simple act of switching off Wi-Fi and switching it back ON again can often help in fixing Wi-Fi Connectivity issues on iPhone.
1. Open Settings > tap on Wi-Fi.
2. On the next screen, move the toggle next to WiFi to OFF position.
3. Wait for 30 seconds > switch ON Wi-Fi by moving the toggle to ON position.
2. Restart iPhone
Another simple fix that often works in fixing network connectivity problems is to Power OFF and Restart your device.
1. Go to Settings > General > scroll down to bottom and tap Shut Down.
2. On the next screen, use the Slider to Power OFF your device.
3. Wait for 30 seconds and then restart iPhone by pressing the Power Button.
3. Turn OFF Wi-Fi Assist
The problem could be due to your iPhone automatically switching from Wi-Fi to cellular network, due to Wi-Fi Assist feature being enabled on your device.
1. Go to Settings > Cellular.
2. On the next screen, scroll down and disable Wi-Fi Assist by moving the toggle to OFF position.
After disabling Wi-Fi assist, reconnect to your Wi-Fi network and see if Wi-Fi is now working on your iPhone.
4. Power Flush Modem/Router
1. Switch OFF the Power Supply to your Modem/Router – Use the switch (if available) or Unplug the power cable from the wall socket.
2. Make sure you wait for at-least 60 seconds and restore back the power supply to Modem.
The above step resets Wi-Fi Network, assigns a New IP Address to your iPhone (if required) and can help in fixing most Wi-Fi connectivity problems.
5. Forget WiFi Network and Rejoin
Forgetting Wi-Fi network and re-joining the network is known to help in fixing Wi-Fi connectivity problems.

4. Wait for 60 seconds > select your Wi-Fi Network > join Wi-Fi Network by entering your Wi-Fi password.

Before following this step make sure that you note down your Wi-Fi Network Password as it will get erased.
