vivo mobile phone connection WiFi network speed is slow, can refer to the following methods to solve:
1. First, compare the network speed of other mobile phones connected to the same WiFi to determine whether it is the problem of the mobile phone or the problem of WiFi;
2, Go to Settings -- more Settings -- Apps -- All -- Find WLAN-- click Storage, clear data and cache, and try to connect again;
3, check or reset the Settings of the wireless router, wired broadband or replace a new wireless router to try. (At the same time, the WiFi network speed is related to the distance from the router, the bandwidth of broadband and the number of people connected) 4, if the network speed is still slow after checking and resetting the router, you can enter the mobile phone Settings - System upgrade to detect whether the mobile phone upgrade is the latest version. If not, you can upgrade to the latest system and try connecting again. 5, if the phone is upgraded to the latest version or is already the latest version, this phenomenon still exists. It is recommended to go to the phone Settings - more Settings - Backup and reset\/restore factory Settings - restore all Settings to see. If it still cannot be solved after restoring all Settings, it is recommended to send the phone to the vivo after-sales service center for testing and processing, and the address and contact information of the vivo after-sales service center can be queried in the vivo official website - Service network query. Note: You can call to confirm the after-sale working time and plan your trip reasonably.
