Problem description: Several of our computers are connected to the Internet through the TP-Link SOHO Router R402M router. In the past, you could make some settings by logging in to the router, such as opening the corresponding port used by BT.

Recently, I found that I couldn't log in to the router with it, but I was able to ping normally with ping; Using the tel prompt cannot open the connection to the host, on port 23: connection failed. It's the same with other computers.

I suspect that the webmaster has done something because I found out that the port used by my BT has been shut down.

If you press "Reset" directly on the router, then the ADSL dial-up and password saved on the router are gone. And we don't have ADSL dialing, passwords. So pressing "Reset" is not a no-go.

Is there any way to log in to the router and open the corresponding port used by my BT?

Question added: I've tried, etc.

And the ping is normal ping.

If the router IP has been changed, then our gateway must also be changed, since our gateway is still the same, then it should be able to judge that the router IP has not been changed.

Resolution: It must be a DNS error.

Being able to ping proves that there is no problem with the protocol and the physical connection, but your DNS is wrong, change your DNS to log in again.

Isn't there an instruction manual? If you lose it, go to the official website to find the next manual for the same model, and follow the instructions on the manual step by step.
