Hello, Baimo is very happy to serve you 1. Check whether the WiFi connected to the device can be used normally, and eliminate the cause of the WiFi itself; 2. If you have your own WiFi, you can try restarting the router;If it is a public WiFi, you can try to change to another WiFi; 3. Enter the settings -- WLAN -- click the connected WiFi -- forget the password -- re-enter the password to connect; 4. Enter Settings - More Settings - Applications - All - WLAN Services - Clear Cache and Data; 5. The number of users around, different time periods, and the distance from the WiFi transmission source will also affect the WiFi network speed. You can try changing the time period; 6. If other devices connect normally, only your phone cannot connect, which may be caused by abnormal WiFi configuration. You can set static IP, DNS and gateway to connect to WiFi. Thank you for your support for vivo mobile phone, and wish you a happy life!
Seeking fans is not useless. Good posts are promoted. In a once-in-a-century country, they have not spoken for a hundred years. That does not reflect your value, but also makes good posts sink quickly. So at a critical moment, I will ask for chalk.
