If only the WiFi password is changed, but the WiFi name is not changed, relevant settings must be made on the phone at this time, otherwise the phone will not be able to connect to the WiFi signal.
If both the Wi-Fi name and Wi-Fi password are modified, no other settings are required on the phone at this time, and the phone can directly search and connect to the new Wi-Fi signal to access the Internet.
If you only modify the Wi-Fi password, but not the Wi-Fi name, you need to delete the Wi-Fi record saved in the phone (that is, the relationship between the saved Wi-Fi name and the password). After deleting, when the phone connects to the original Wi-Fi signal, it will prompt to enter the Wi-Fi password; at this time, enter the modified Wi-Fi password, and you can successfully connect to the Wi-Fi signal.
