GL-MT300N password error

Hello,

I’ve tried to login to the Router GUI, entered the password and it won’t let me login. I receive a short notification of “input is wrong” and it won’t let me log in. I’ve tried goodlife and all other optional passwords I could have had. Any idea on how to reset the password without doing a complete factory input? All I want to do is change the VPN server…

Thanks!

While seems the best way is to reset the router completely the upgrade the firmware.
