Solution 1: Check the physical connection.
1 Make sure the physical connection between the router and the modem is
proper.
Solution 2 Clone the MAC address of your PC.
Note: 1 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
2 The MAC addresses of a computer in wired connection and wireless
connection are different.
1 Visit http://tplinkwifi.net, and log in with the username and password you set
for the router.
2 Click Advanced > Network > Internet to enter the configuration page;
