TP-Link WR842ND problem


I've installed the proper openWRT firmware on my TP-Link WR842ND.
After reboot, I've tried to connect to or 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?


Which firmware did you install? Snapshot? After install login with user: root. No password required. You can change it after you login with passwd command

openwrt ar71xx-generic-tl-wr842n-1-squashfs-factory.bin

I tried with root and no password
doesn't work
