Advanced Preparations 
1Turn off your modem, router and computer.
2Connect your modem to the WAN port of the TP-Link router via an Ethernet cable; connect a computer to TP-Link router’s LAN port via an Ethernet cable.
3Power on your router and computer first and then modem.
Step 1
Log into the router’s web-based management page
Step 2
Configure WAN Connection Type.
After log into the router, click Network > WAN on the left of the web page:
Select Dynamic IP as the WAN Connection Type on the right of the web page, shown as below. Then click save button.
Step 3 
Wait for a few minutes and check the WAN part on the Status page, if it shows any IP address, which means the connection between the Router and the Modem is established.
Note: If there is no WAN IP address, please click Network->LAN in the left side menu; change the IP Address to a different segment. Then click “Save”.
For example, most TP-Link routers use as their default LAN IP address, it may conflict with the IP range of your existing ADSL modem. If so, the router is not able to communicate with your modem and that’s why you can’t access  Internet. To resolve the problem, we need to change the LAN IP address of the router to avoid IP conflict, such as After you changed the LAN IP address, next time you need to use the new IP address to access the router’s management page.
