Wi-Fi Not Working On iPhone But Working On Other Devices: Troubleshooting Steps

After facing Wi-Fi issues on my phone, while other devices connected smoothly, I realized it’s a surprisingly common problem. No need to fret though – this can typically be fixed with straightforward solutions. In this guide, we will delve into the why and how of this, offering you ways to navigate and resolve these Wi-Fi woes. So, let’s dive in!

Possible Causes and Solutions

A Wi-Fi issue on your phone can stem from several sources, often differing vastly in nature. Here’s a quick rundown of the most common causes and their corresponding remedies:

  1. Incorrect Password: Make sure you’ve got the right credentials for your Wi-Fi connection.
  2. Weak Signal: Being too far from the router could be the problem. Try to shorten the distance, or consider a Wi-Fi extender.
  3. Interference: Other electronic devices can disrupt Wi-Fi signals. Keeping them away from your phone might help.
  4. Software Problem: Potential bugs in your phone’s system could be the culprit. A phone restart or system update could resolve this.
  5. Hardware Problem: If none of the above applies, a hardware issue might be at play, and a visit to the repair shop could be in order.

In the following section, we will delve deeper into these issues, providing you with a comprehensive understanding of each and more. So, keep reading!

1. Incorrect Password

Incorrect password input is a common cause of Wi-Fi connection issues on phones. When you connect to a Wi-Fi network, your phone needs to authenticate the connection by using the correct password. If the password is wrong, your phone won’t be able to establish a secure connection, which results in the Wi-Fi not working.


Make sure you’re entering the correct password. Passwords are often case-sensitive, so ensure that you’re entering every character accurately. If you’re unsure about the password, check with the network owner or the person who set up the Wi-Fi network. If you are the network owner and have forgotten the password, you may need to reset it via your router’s settings.

Keep in mind, regularly updating your Wi-Fi password boosts your network’s security, and maintaining a record of the current password could save you from connection headaches down the line.

2. Weak Signal

Wi-Fi signals, just like any other radio signals, weaken as they travel further from their source, in this case, the router. When you’re too far away, the signal becomes too weak to establish a reliable connection, and your phone may struggle to maintain a stable Wi-Fi link. Walls and other physical obstacles can also interfere, further reducing signal strength.


Try moving closer to your router. If your phone’s Wi-Fi works well when you’re in the same room as the router but struggles as you move away, a weak signal might be the culprit. In larger homes or buildings, you may want to consider using a Wi-Fi extender or a mesh network system. These devices can amplify the signal, effectively extending the range of your Wi-Fi network and providing a stronger signal in areas that were previously out of reach.

3. Interference

Interference is another common issue that can disrupt your phone’s Wi-Fi connection. Other electronic devices, such as microwaves, cordless phones, or even your neighbors’ Wi-Fi networks, can operate on the same frequency as your router, leading to interference that weakens your Wi-Fi signal. This interference can result in a slower connection or cause your Wi-Fi to drop out entirely.


You can try to alleviate interference by moving your phone away from devices that may cause it. If your Wi-Fi problems seem to occur only when certain devices are in use, those devices might be the culprits. Also, consider changing your router’s channel through its settings. Most routers are set to auto-select a channel, but if neighboring networks are using the same channel, switching to a less crowded one can help reduce interference.

4. Software Problem

Sometimes the Wi-Fi issues you’re experiencing aren’t due to your network at all, but a software glitch on your phone. Software issues can range from minor bugs that cause occasional hiccups in connectivity to more severe problems that prevent you from connecting to Wi-Fi altogether.


A simple yet effective solution for software-related Wi-Fi problems is restarting your phone. This can often clear minor software glitches that are causing issues. If the problem persists, check if there are any pending updates for your phone’s operating system. Keeping your device updated can resolve any software bugs that might be affecting Wi-Fi connectivity.

For persistent issues, consider using third-party software like Tenorshare ReiBoot. This is an iOS system recovery tool that swiftly fixes software bugs on your iPhone, potentially resolving your Wi-Fi issues. It’s easy to use – connect your phone to a computer, run ReiBoot, and follow the on-screen instructions to repair your device’s system. Remember, always backup your data before performing any major software fixes.

5. Hardware Problem

If you’ve exhausted all the above methods and your phone’s Wi-Fi is still not functioning, you may be dealing with a hardware issue. A hardware problem can range from a simple issue like a faulty antenna to something more serious like damage to the Wi-Fi chip on your phone’s motherboard.


In the case of a potential hardware issue, it’s advisable to get professional help. Schedule a visit to a nearby authorized repair center. If your phone is an iPhone, contacting Apple Support or visiting an Apple Store would be your best course of action. They have trained technicians who can diagnose and fix the issue. Remember, unauthorized repairs can void your warranty and may cause more harm than good. It’s crucial to ensure that your device is in safe hands.

Further Troubleshooting Steps

Even after identifying the potential causes, you might find that your Wi-Fi issue persists. In such cases, a more systematic approach to troubleshooting might be necessary. Here, we will discuss in detail, some of the most effective troubleshooting methods:

Checking the Wi-Fi Router

Your Wi-Fi router could potentially be blocking your device or facing some glitches.


  1. Visit your Wi-Fi router physically.
  2. Either unplug the router and plug it back in after a few seconds or hit the reboot button, if available.
  3. Wait until the router fully restarts, then check if your phone’s Wi-Fi is now functioning.

Reconnect After Forgetting the Wi-Fi Network

This method essentially refreshes your phone’s connection to your Wi-Fi network.


  1. On your phone, navigate to Wi-Fi settings.
  2. Select the troublesome network and choose the ‘forget network’ option.
  3. After forgetting the network, locate the same network again in the list of available networks, and reconnect by entering your password.

Reset Network Settings

This method clears all your network settings, providing a clean slate for your device to connect to networks.

Author’s Note: This worked for me.


  1. Go to your phone settings.
  2. Locate and tap on the ‘reset network settings’ option. Remember, this step will erase all your saved networks and VPN settings.
  3. After the reset, reconnect to your Wi-Fi and verify if it’s working.

Update Your Phone’s Operating System

Sometimes, an outdated operating system can cause Wi-Fi connection problems due to incompatibility issues or bugs.


  1. For both iOS and Android devices, navigate to your phone settings.
  2. Find the ‘software update’ or similar option.
  3. If there’s a new update available, download and install it.

These are some of the further troubleshooting steps you can take to address Wi-Fi issues on your phone. It’s important to remember that the order of these steps does not necessarily reflect their effectiveness. You can try them in any order, or skip some based on your specific situation.
