Please check whether you have entered an 8-digit password. If no, reset your router's
password. Change the authentication's encryption mode to WPA-PSK or WPA2-PSK, and set
the password to contain 8 numeric numbers. Then try again. You are suggested to select the
option for displaying the password to check whether the entered password is correct.
Check whether the hotspot name is hidden. In the router settings, cancel the hotspot
hiding function. It is recommended that you set the English SSID.
Use your phone to scan the hotspot near the router (3–5 meters).
If no hotspot is found, restart your phone. If the phone still fails to locate any hotspot,
take your phone to an authorized Huawei service center to check the hardware.
