Why does the Tianyi mobile phone given to me by Telecom fail to connect to the wifi at home, and there is always an authentication error?

Hello, first of all, thank you for your support to China Telecom. According to your description, your wireless password may have been entered incorrectly. Please re-enter the password or enter the wireless router to reset the wireless password.

If you need to check the bill and pay the phone bill, please go to the online business hall of Anhui Telecom. Wish you a happy life!

I hope my answer will help you and be adopted by you!
