How to solve the problem of slow wireless network speed?

If you are using a vivo phone, you can troubleshoot according to the following methods:

If WiFi and Bluetooth are used at the same time and the WiFi speed is slow, first please confirm whether the WiFi connection is 2.4GHz frequency band:

①?2.4Ghz?WiFi: The working frequency band of Bluetooth and WiFi signals are both 2.4GHz. If the signals are turned on at the same time, interference will occur, which may cause difficulty in device pairing, intermittent interruption of WiFi, and network Restricted, Bluetooth audio intermittent and other phenomena. It is recommended to prioritize WiFi use in the 5GHz band to reduce interference.

②Non-2.4Ghz?WiFi?: It is recommended to enter the router settings page and try to change the WiFi channel in the router settings (select the maximum value) and observe.

If it does not fall into the above phenomenon, you can troubleshoot and handle it according to the following methods:

1. It is recommended to restart the router and upgrade the router to the latest version to check whether the network is restored.

2. The strength of the WiFi signal is related to the usage environment (such as walls, too far away, etc.). If the signal is weak/the Internet is slow, it is recommended to adjust the distance between the mobile phone and the WiFi router before trying again.

3. Both WiFi and Bluetooth use the 2.4G frequency band. If your mobile phone uses Bluetooth, it is recommended to turn off Bluetooth and then test again. If the mobile phone and router support 5G WiFi, it is recommended to connect to the 5G WiFi to check whether the network speed is normal (the name of the 5G WiFi is usually XXX-5G). In addition, check whether there is interference from high-power equipment nearby. If there is a microwave oven or other equipment, it is recommended to adjust the position of the WiFi router and test again.

4. Please connect to different WIFI networks and compare the speeds of different WIFI networks to see if the WIFI network itself is slower.

5. Go to Settings--System Management--Backup and Reset--Reset Network Settings--Reset Settings and check again.

Note: For dual SIM cards, you need to select the corresponding SIM card; resetting network settings will delete and disconnect the connections and pairing records of WLAN, mobile data network, Bluetooth and other networks. It is recommended to back up your WiFi account before operation. and passwords and other data, you can enter cloud services--data synchronization--turn on WLAN, Bluetooth, etc. to synchronize data to cloud services; enter "cloud services"--device cloud backup--backup data type--open "system data" --Return to the previous page--Back up immediately to back up some system setting data.

6. If there is no "Reset Network Settings" menu option on the mobile phone, you can enter Settings--System Management/More Settings--Backup and Reset/Restore Factory Settings--Restore All Settings-- reduction. ?

Note: Restoring all settings will not delete any data or media files, but will only restore all settings of the phone (such as set wallpapers, unlocking styles, WiFi, default startup programs, desktop layout, etc.), and Some third-party application accounts require logging in again. Please make sure it does not affect the use of the software before proceeding. For data security, it is recommended to back up mobile phone data in advance before operation. (You can enter Cloud Service - Device Cloud Backup - Backup Data Type - System Data - Return - Backup Now to back up some system settings and desktop layout; Cloud Service - Data Synchronization - Turn on WLAN, Bluetooth, etc. Synchronize the data to the cloud service)

7. If the above method fails to solve the problem, please back up important data on the mobile phone in advance and take the mobile phone to the vivo customer service center for inspection and processing.

Warm reminder: It is recommended to bring relevant purchase certificates (such as purchase invoice/warranty card/ID card) when going, and call the service center staff in advance to ensure that the staff will go during normal working hours. Avoid empty running and pay attention to safety on the way to and from the place.
