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.

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’.

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.
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.
