How to manage TL WR841ND router via telnet or ssh?

Question

network hardware

In all this, I am a complete layman, Google did not lead me to anything intelligible, so I ask for help here, how to connect to this router via telnet or ssh

Answer 1

Install openwrt firmware on the router , there is a web interface and the ability to control via the console via ssh and telnet.
In stock firmware, ssh and telnet may not be supported.

Answer 2

This means that telnet is disabled on the router. This is done for safety.
And the remote control port is the port on which the web interface of the router is available.
