1. Please make sure your WLAN signal is good
Please restart your phone, pull down the notification bar, and then long-press on the WLAN icon, and then check the WLAN interface to make sure. If the signal is weak, it is normal for the phone to disconnect and reconnect, so we recommend that you move to a place with a better signal.
2. Please restart, reset, or upgrade your router
Please make sure that the phones around you are using the same WLAN network, and if so, the router may be acting abnormally.
It is recommended that you restart your router, reset your router, or upgrade your router version. (To upgrade your router version, click "Software Upgrade" in the router setup interface, and then click "Online Upgrade" or "Local Upgrade. Upgrade to the latest version by clicking "Software Upgrade" in the router setup interface, and then upgrade to the latest version through "Online Upgrade" or "Local Upgrade". You can consult with your router equipment provider for specific router settings and upgrade operations.)
3. It is recommended that you set your WLAN to always keep WLAN connected when you are sleeping
If your phone's WLAN network is disconnected in standby, and reconnected when the screen is on, you can set your WLAN to always keep WLAN connected when you are sleeping, as follows:
EMUI 8.X and below: Search in Settings and turn on Keep WLAN connection while hibernating, set to Always.
EMUI 9.X&Magic UI 2.X and above: Search for and turn on the Keep WLAN connected while hibernating switch in Settings.
4. Try Restore Network Settings
We recommend you search for Restore Network Settings in Settings and click on it to enter, restore network settings and retry.
Warm reminder: This operation will restore all network settings, including: WLAN, Mobile Data Network and Bluetooth.
If the above methods still can't solve your problem, please back up your data in advance (WeChat/QQ and other apps need to be backed up separately), and bring your proof of purchase to the nearby Huawei Customer Service Center for repair.
