I've installed the proper openWRT firmware on my TP-Link WR842ND.
After reboot, I've tried to connect to 192.168.0.1 or 192.168.1.1 with putty using telnet or ssh.
The telnet doesn't work and on ssh, it require a user default(root) and a password.
I tried with 'passwd' or only enter but after 5 retries the system it tells me that I have to wait 500 seconds to retry.
I want to say that the busy box doesn't appear... only a user and password.
What can i do to reinstall openWRT or to revert the changes?
