4. Ensure That Your Router is Working Properly

When the WiFi connection on your phone is not working, an important step to troubleshoot the issue is to check if the router is working properly.

Here are the steps to do this:

  • Ensure that the router is plugged in and switched on.
  • Inspect all the connections and cables to ensure that they are plugged in properly and securely.
  • Check if your router’s lights show that there is a connection. If the light is flashing or there is no light, there might be an issue with the connection.
  • Reset your router by unplugging it from the power outlet, giving it a few seconds, and plugging it back in. This will refresh the connection and help establish a new one.
  • Regularly check your router/modem for software updates. These updates help in fixing bugs and improving the performance of the modem/router, hence solving any connectivity issues.

5. Check for Any Interference

If other electronic devices are causing interference, it may affect your phone’s WiFi connection.

Below are a few things that you need to check:

  • Check for other WiFi networks: your phone may be trying to connect to the wrong network if there are many WiFi networks in your area. Move closer to the router to improve the strength of the signal or try switching to a different network.
  • Check for electronic interference: Electronic devices in your home such as baby monitors, cordless phones, and microwaves can disrupt the wireless signals. Try moving the electronic devices away from the router or moving your phone closer to it to see if this solves the problem.

6. Turn Airplane Mode On & Off

Your phone’s WiFi connection can also be affected by Airplane mode so another step you can take is to turn Airplane On and Off to see if that improves the quality of the connection.

To implement this on iPhone, follow the steps below:

  • Open the Control Center by swiping up from the bottom on older iPhone models or swiping down from the top right corner of the screen on iPhone X and later models.
  • Click on the Airplane mode icon, which is similar to a small airplane.

For Android, follow the steps below:

  • Scroll down to the main menu.
  • Click on the Airplane mode icon to turn it on.
  • Turn it off after a few seconds then turn the WiFi on.
  • Now check whether your phone has a connection.

7. Check for Software Updates

Up-to-date phone software improves security, adds new features to your phone, improves network speed, and helps in solving WiFi connectivity issues.

Your devices need to stay updated, but before proceeding with any update, ensure that any necessary information is backed up because newer versions of operating systems may need additional reconfiguration or adjustments.

8. Inspect Your Phone’s Hardware

Inspecting the physical parts of your phone such as circuit boards, ports, and internal antennas can help diagnose a variety of potential issues. Check the back of your phone for any loose WiFi antenna connections.

Check all the external ports to see if there is any damage that might be preventing the transfer of data. If you notice that there is something out of place in the ports such as dust particles, use compressed air to dislodge them.

Additionally, you should contact a specialist to run a few diagnostics on the hardware inside the phone and perform in-depth tests to check whether something is wrong that may be causing the connectivity issues.

9. Disable Battery-Saving Mode

When the battery-saving mode is enabled in some models, access to system resources can be limited which may reduce the phone’s performance.

Additionally, some background applications that use the internet connection may be disabled or restricted when this feature is on.

Disabling the battery-saving mode will ensure your phone has full access to the system resources that are needed to maintain a stable connection.

10. Manage Congestion by Turning Off Bluetooth, Changing Frequency Bands, or Configuring the Quality of Service

Bluetooth can easily interfere with WiFi networks because both WiFi and Bluetooth send signals using the 2.4 GHz frequency band.

Sometimes Bluetooth can significantly slow down the internet speed and it can also cut off access entirely.

You can easily test this by turning Bluetooth off on your phone and checking whether you can now connect to WiFi.

If this solves the problem, we recommend that you switch your router to the 5 GHz band from the 2.4 GHz band to ensure the Bluetooth network does not cause WiFi connectivity issues.

Switching bands is a recommended step in case there is any network congestion on one of the bands. To do this, go to the settings on your router and change the bands.

Typically, the 5 GHz band is recommended because it has more bandwidth available for better performance and reduced latency.

If both bands appear congested, you can also configure the Quality-of-Service settings to allow the router to prioritize specific traffic over others. You can also limit the number of connections on the network.

11. Ensure Proper Placement and Range of Your Modem/Router

Poor WiFi connectivity on your phone can be caused by the wrong placement of your modem/router or when one of the devices is out of range.

Make sure that there are no physical obstructions between your phone and the modem/router such as large furniture or walls.

Place the modem/router closer to your phone for easier network connectivity.

12. Change Your Password

Changing your WiFi password will help prevent connectivity problems related to forgotten passwords as well as increase the security of your network and devices.

To ensure that no devices are using your network without permission, you should change your password regularly and only share it with the people you trust who need access.

Create a strong password by mixing numbers, lowercase, and uppercase characters to prevent hackers from easily guessing it.

Also, use anti-virus software that is regularly updated on each device that uses the network to prevent any cyber-attacks.

13. Temporarily Disable Proxy or VPN

Proxy and VPN are tools that provide users with different ways of connecting to certain websites and networks by encrypting data to ensure it is safe from potential threats.

If these services are kept active for too long, they can congest connections and even overload the network.

To disable proxy/VPN on iPhone, follow the steps below:

  • Open Settings, click on General, and then select VPN.
  • Turn off the connection.
  • Click ‘Delete Profile’. It is optional.
  • Reboot your phone when the process is complete.

To do this on Android, follow the steps below:

  • Go to Settings>Connections>More Connection Settings.
  • Tap on Mobile Network>Access Point Names>Clear all APNs>OK.
  • Click on the three dots at the top right corner and choose ‘Advanced’.
  • Under the Advance menu button, select ‘Proxy’ and turn it off.

Check whether you can now connect to your WiFi after disabling the Proxy or Virtual Private Network on your phone.

14. Contact Your Service Provider

If you have tried all the steps mentioned above and nothing works, you should contact your internet service provider as they may be experiencing issues with the internet on their end.

They will advise you on what to do, whether your router/modem needs any repair, or you just need to wait until the network is back on in case of an outage.

Final Words

If the WiFi connection on your phone is not working properly but other devices can connect to the same WiFi, there are reasons why.

The cause of this issue may be linked to your phone, modem router, or the internet service provider.

Some of the steps that you can follow to troubleshoot this problem are restarting your phone, ensuring that your router is working properly, or keeping the network less busy by reducing the number of devices connected to it.

If none of the solutions mentioned above resolve the problem, contact a technician or your ISP for assistance.
