I have TP-link which I re-installed the DD-WRT firmware on TP-Link WR740N
and the firmware version is: DD_WRT v24-sp2(03/25/13)std -build 21061
So I can login to router using only web interface and Telnet, but when I use PuTTY to login to DD-WRT router via SSH, PuTTY warning me with this message:
Putty Fatal Error
Server unexpectedly closed network connection
So, how to solve this problem?
