Today, Wi-Fi - a wireless networking technology - is an indispensable part of our digital life, allowing your iPhone, tablets, and other gadgets to connect to the internet without any physical connections. When we stay at home or in public places, we're used to connecting iPhone to a Wi-Fi to browse the internet. But sometimes wireless connection issue does occur.

Here's a sad but somewhat common story. Your iPhone suddenly disconnects a Wi-Fi after using for a while or when it goes into sleep mode. Then you have to navigate to Settings and rejoin the Wi-Fi to continue surfing the web with your iPhone.

If your iPhone also can't stay connected to Wi-Fi network, you can read on as we talk you through some useful Wi-Fi troubleshooting tips.

Start with the basics: Check, turn off/on, and restart

Before you try more complicated steps to fix your issue, it's best to start with the usual workarounds. Let's look at these no-brainer solutions.

  • Check if your iPhone is within the internet range. The range can vary depending the type of the network. E.g.: The range of home networking using a router operating on the 2.4 GHz band generally can reach up to 150 feet indoors and 300 feet outdoors.
  • Make sure you turn off Airplane mode. If your iPhone is in Airplane mode, it won't stay connected to the Wi-Fi. Thus, you should go to Settings to check it, and disable it if it's turned on by accident.
  • Ensure that you've turned on Wi-Fi. If a Wi-Fi sign doesn't appear on the top left of your iPhone screen, that means it is turned off. Just navigate to Settings to turn it on.
  • Restart your iPhone. As we know, rebooting can resolve many technical issues. So, feel free to try this fix. But before that, you can check if there's new iOS available to download. Maybe the bug in old iOS system prevents your iPhone from keeping connected to Wi-Fi.
  • Verify your router connection. Check your router or modem and make sure the router cable is not loose and attached poorly. If not, you can try to restart the router and then reconnect your iPhone. A modest proposal: use a dual band router; it provides faster speed and flexibility so that your iPhone will always be in a stable wireless network connection.

If none of these simple troubleshooting steps can fix "iPhone won't stay connected to Wi-Fi network" issue, you can scrutinize a comprehensive guide below.

Quick Note: The problem perhaps results from software-related issue on your iPhone. In this case, using iOS System Recovery application is a quick fix. This section presents specific steps.

Forget the Wi-Fi network you're connecting and rejoin it

It's possible that the issue disconnecting to wireless network could be the result of a changed password or network name. To fix it, you can try to forget the Wi-Fi and then reconnect it, but you need to get the correct (new) password or network name first.

1. In the Settings, tap Wi-Fi. You will see the network you've connecting (there's a check mark next to it).

2. Tap the network and select Forget This Network. Then, tap Forget to confirm.

3. After that, the "forgotten" network will appear in the "NETWORKS" list. Tap the network name > Join This Network and enter the correct password.

4. Now you can use your iPhone to watch some videos, or put it aside. After some time, you check if your iPhone keep connecting the Wi-Fi. If so, that indicates the fix is workable.

Note: Make sure you toggle on the switch of "Auto-Join" in the Wi-Fi your phone usually connects to. Just tap the network name, then you will see "Auto-Join" switch. After this, whenever you're in the network range, your iPhone will automatically connect to the network.

Renew lease

If you're on a public place, like coffee shop, restaurant, supermarket and library, the network your iPhone has connected to may be time-limited. In other works, your iPhone won't stay connected to the Wi-Fi connection after a defined period of time - a week or a few hours depending on how the server has been set up. Under the circumstance, you need to renew lease.

In general, you should use an IP address to connect a Wi-Fi, and DHCP (Dynamic Host Configuration Protocol) is a tool that can pass out the address. When you find your iPhone keeps you off the Wi-Fi, just renew lease so that the address information gets updated and you get IP address and permission from DHCP to enter the network.

1. Firstly unlock your iPhone and open Settings. Then tap Wi-Fi and select the disconnected network.

2. The next step is to tap "Renew Lease" and tap "Renew Lease" again. You could continue using the Wi-Fi connection.

Reset network settings instead of all settings

iPhone has a common reset feature that allows you to reset all settings on your iPhone - including network settings, location settings, the keyboard dictionary, and the Home Screen layout - to the default, but other data and content won't be erased.

When your iPhone has wireless network issue, you fix it at Settings > General > Reset > Reset All Settings. Enter your passcode, and tap Reset All Settings to proceed. You will see an Apple logo appears on the screen. Once the process of resetting all settings finishes, join a network to check if the problem still exists.

However, that can be overkill, since sometimes iPhone just needs a network setting reset to fix the problem. Resetting network settings is also pretty straightforward, and this won't deleted other content on your device.

Navigate to Settings app, tap General > Reset > Reset Network Settings. Then tap Reset Network Settings again. Your iPhone will restart. Once done, you can choose a Wi-Fi network to connect your iPhone.

Disconnect overmuch device, try other devices

If you're using home Wi-Fi, a multitude of devices are sharing the same wireless network at the same time, which is a common phenomenon. But, sometimes, the internet speed will slow down or even your iPhone disconnects from the Wi-Fi as the router can't support too many devices to be connected at one time. To avoid this, disconnect some devices.

Still having the issue? Then you should check whether or not other devices can stay connected to Wi-Fi when they connect to the same network as your phone. If they work well, chances are that your phone has hardware issue, e.g. the Wi-Fi antenna is damaged. Given this situation, you should ask for Apple support and let technician check your iPhone.

In addition, it's recommended that you try connecting your device to another router to isolate the issue to the router. If the issue persists, you could also consider replace the router.
