For the old UI:
The default login username and password are both “admin”. If you have changed the login password, there is no way to find it. You need to reset it to factory default and configure it as a new one.
For the new UI:
It only asks for the login password which you have created in the first time you log in. If you forget it, you need to reset it.
How to reset the router?
Directly press and hold the reset button on the rear panel with a pin for approximately 10 seconds when the device is running.
Release the reset button and wait for the device to reboot.
1. Make certain that the router is powered on before it restarts completely. 2. The default IP address is 192.168.0.1(or http://tplinkwifi.net ), and the default login username and password both are admin (all lower case).
3. Ensure that the IP address of your computer is in the same subnet as the device. It means that your computer has an IP address 192.168.0.X (X is in the range of 2~253), and the subnet mask is 255.255.255.0.
