Last Update date : 2023-05-11

When you have difficulty connecting to Wi-Fi on your phone, you need to check whether the Wi-Fi signal is not found or if the Wi-Fi network is found but cannot connect. Check out the guide below to successfully get your Wi-Fi network online.

Note: Be sure to check if your device's software and related apps are updated to the latest version.

What to do if the Wi-Fi network is not detected?

There can be various reasons for the problem of not being able to connect to the Wi-Fi network normally. For example, the router may not be working properly or there may be an issue with your phone's network settings. Check out the guide below.

Check if the router is working properly. Make sure that it's powered on, connected to the Internet, and that your phone is within the router's Wi-Fi range. In addition, if too many devices are connected to one router, the Wi-Fi may not be detected.

Try the Wi-Fi connection in Safe mode. If the Wi-Fi network is connected in Safe Mode, it may be a problem caused by the downloaded app on your phone, and that app should be uninstalled. To find which app causes a Wi-Fi issue, you can try uninstalling the apps in the order of the last installation.

Step 1. Press and hold the Volume down key and the Side key.
