Using a tplink router as wireless bridge to extend range

It's usually straight forward nowadays :

• Reset the new router
• Connect to it via WIFI using the default SSID and password given on the back, or WPA
• Login to the new router, at its default I.P, e.g. 192.1681.0.1 or http://tplinkwifi.net/
• You need to create a password at the first login
• Choose the range extender option
• Select your main network from the list
• Choose static I.P and use an I.P in the same subnet as the main router. E.g. if the main router is at 192.168.1.1, you can choose any 192.168.1.*
• Disable DHCP server
• If WPA_PSK does not work, try WPA2_PSK. This was the issue for me.
• Restart and check that the internet light is green
