The tplink router can work normally when connected to my home terminal, but it should be plugged into your Internet port, which is the port where the computer can access the Internet. Plug in other ports, and you may not be able to access the Internet without configuring Internet data.

In addition, you can look at the password settings of the dial-up account in tplink. After changing to my e-home, Telecom may give me a new account password, which needs to be reconfigured by yourself.
