• 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.
• Reset the router to factory default settings and reconfigure the router.
• Upgrade the firmware of the router.
• Check the TCP/IP settings on the particular device if all other devices can get internet from
the router.
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
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
3 ) Modify the LAN IP address as the follow picture shows. Here we take 192.168.2.1 as an
example.
4 ) Click Save.
> MAC Clone, select Clone MAC Address
> LAN.
and click Save.
