What should I do if my Wi-Fi network is not detected?
Every smartphone users face this type of problem but didn’t find a reason. However, there are many reasons why you cannot successfully connect to a Wi-Fi network. For instance, your router or native mobile data might not work properly or there’s a problem with your phone’s network settings or there could a software-related issue mostly with OxygenOS 12.1 update.
Your first step is to check for the Android software update – you can manually check for OTA updates by navigating to [Settings] – [System] – [System Update] – [Check for Updates] – [Download and Install Now].
After you must check if your router is working properly. Make sure it’s on, connected to the Internet, and that your phone is within the Wi-Fi range of your router. Also, Wi-Fi may not be detected if multiple devices are connected to the same router.
If you’re connected to a Wi-Fi network but can’t get online, try using a Wi-Fi network on another device. If other devices also can’t get online, there may be a problem with their network service, so check with your Internet provider.
