  1. Really great service. Receiving the code took less than a day, and I think it would have been even quicker if I hadn’t ordered in the late afternoon. Unlocking was really easy, small correction: There actually isn’t an “Unlock” option, the router will be unlocked right after flashing the firmware and restarting! Overall really impressive, definitely recommended

    • No, the password is not changed. It is same like earlier. If you forget the old password, then you can reset that using the reset button given at the back. The password will change back to admin.
