Can you help

[Zammi]

Have you flashed any custom ROM? You can download original firmware from SamMobile.com.

But I recommend you to first try to update your phone with smart switch.

We apologize for any inconvenience this may have caused you. 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.

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 1. Make sure the router is available
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.

Check 2. Restart the devices
Try restarting your Galaxy phone, router, and modem.

Step 1. Press on the Volume down button and Power button at the same time.

Close the charging case again and open it to enter Bluetooth pairing mode.
