If the IP Address is 0.0.0.0, please try the methods below and try again:
•Make sure the physical connection between the router and the modem is proper.
•Clone the MAC address of your computer.
1 )Visit http://tplinkwifi.net, and log in with the username and password you set for the router.
2 )Go to Network > MAC Clone, select Clone MAC Address and click Save.
Tips:
•Some ISP will register the MAC address of your computer when you access the internet for the first time through their Cable modem, if you add a router into your network to share your internet connection, the ISP will not accept it as the MAC address is changed, so we need to clone your computer’s MAC address to the router.
•The MAC addresses of a computer in wired connection and wireless connection are different.
•Modify the LAN IP address of the router.
Note:
Most TP-Link routers use 192.168.0.1/192.168.1.1 as their default LAN IP address, it may conflict with the IP range of your existent ADSL modem/router. If so, the router is not able to communicate with your modem and cause you can’t access the internet. To resolve this problem, we need to change the LAN IP address of the router to avoid such conflict, for example, 192.168.2.1.
1 )Visit http://tplinkwifi.net, and log in with the username and password you set for the router.
2 )Go to Network > LAN.
3 )Modify the LAN IP address as the follow picture shows. Here we take 192.168.2.1 as an example.
4 )Click Save.
•Restart the modem and the router.
1 )Power off your modem and the router, and leave them off for 1 minute.
2 )Power on your modem first, and wait about 2 minutes.
3 )Power on the router, and wait another 1 or 2 minutes and check the internet access.
•Double check the Internet Connection Type.
1 )Confirm your Internet Connection Type, which can be learned from the ISP.
2 )Visit http://tplinkwifi.net, and log in with the username and password you set for the router.
3 )Go to Network > WAN.
4 )Select your WAN Connection Type and fill in other parameters.

•Please upgrade the firmware of the router.
If you’ve tried every method above but cannot access the internet, please contact the technical support.

•Make sure the wireless function of your device is enabled if you’re using a laptop with a built-in wireless adapter. You can refer to the relevant document or contact the laptop manufacturer.
•Make sure the wireless adapter driver is installed successfully and the wireless adapter is enabled.
•On Windows 7

2 )Clicking Troubleshoot and windows might be able to fix the problem by itself.
•On Windows XP
1 )If you see the message Windows cannot configure this wireless connection, this is usually because windows configuration utility is disabled or you are running another wireless configuration tool to connect the wireless.

If you can find your wireless network but fail to connect, please follow the steps below:
•Authenticating problem/password mismatch:
1 )Sometimes you will be asked to type in a PIN number when you connect to the wireless network for the first time. This PIN number is different from the Wireless Password/Network Security Key. Usually you can only find it on the label of your router.
