2. In the Settings menu, find the \"Connection Function\" or \"Connection Settings\" option and click to enter.
3. In Connection Features or Connection Settings, look for the \"WLAN\" or \"Wi-Fi\" option. If the phone supports Wi-Fi, you should be able to find this option.
4. Click the \"WLAN\" or \"Wi-Fi\" option to enable it. At this point, the phone will start searching for available Wi-Fi networks.
5. In the list of available networks, select a network and click \"Connect\". If the network is encrypted, you may need to enter a password.
6. After the connection is successful, you can access the Internet normally.
