network or at a place with fewer users.

Check whether you have entered a correct password. Pay special attention to special
characters in Chinese or English. You are suggested to select Show password (the eye
icon at the right part of the password input box) to check whether the entered password is
correct.
If the entered password is confirmed to be correct, change the router's password to
numeric numbers only, for example, 12345678.
If the authentication still fails, restart your phone.
Check whether protective measures are configured on the router, for example, MAC
address filtering.
If no protective measure is taken, check the number of connected users on the router.
You can modify the Wi-Fi password of the router to filter other unauthorized users.
Restart your phone or the router.
Restart your phone or the router.
If the problem persists, set a static IP address for your phone.
Check whether other phones can successfully access the Internet. If not, check whether
the network is normal.
