Why can t the mobile phone be connected to the Internet with wifi after changing the optical fiber?

If your mobile phone cannot access the Internet after connecting to the wireless network, we recommend that you first check whether other devices can connect to the wireless network normally. If only your device can't, it is recommended:

1.Use the built-in browser to log in to the webpage and see if the link can be opened normally.

2.If a networking software is not available, it is recommended to check whether the function is set to prevent individual applications from using Wi-Fi. Operation:
