When you wanna bridge the new WiFi to your own WiFi you must have a Lan wire to type C converter as some laptops do not have Lan wire USB port as the new WiFi needs to be connected to the laptop in order to go to the wifi.
Once plugged in go into the WiFi local server http://192.168.1.1/http://192.168.0.1/http://tplinkwifi.net.Once in, log into the account. The admin and password can be found at the back of the wifi.
Once in what you have to go to operation mode and put range extender.
