Hello, first of all, thank you for your support to China Telecom. According to your description, if your computer can't plug in the Internet, you can't set up a router. You can borrow someone else's computer to set up your wireless router, and then connect with your computer and you can surf the Internet normally.
China Telecom's 4G has been officially commercialized. If you need to inquire about 4G tariffs, check bills, pay phone bills and buy mobile phones, please visit the online business hall of Anhui Telecom. Wish you a happy life!
I hope my answer will help you and be adopted by you!
