What should I do if I cannot access the internet through Wi-Fi router?

Step 1. Make sure the physical connection between the router and the modem is proper.  Your modem should be plugged into WAN/Internet port of TP-Link router.

Step 2. Connect computer to your modem directly to check the connection. If there is no internet from your modem, please reboot your modem. Please contact your Internet Service Provider if there is still no internet access.

Step 3. Clone the MAC address of your computer.

1). Connect computer back to TP-Link router via a cable. Login the web interface of TP-Link router and then go to Advanced > Network > Internet and focus on the MAC Clone section.

2). Choose Use Current Computer MAC Address and click Save.

Tips: when you do the MAC Clone, please use wired connection on your computer.

Step 4. 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, which may conflict with the IP range of your existing ADSL modem/router. If so, the router is not able to communicate with your modem and 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.

You may login the web interface of your TP-Link router and then go to Advanced > Network > LAN. Modify the LAN IP address as the follow picture shows. Here we take 192.168.2.1 as an example. Click Save.

Step 5. Restart the modem and the router.

1) Power off your modem and router, and leave them off for 1 minute.

2) Power on your router first, and wait about 2 minutes until it get a solid power.

3) Power on the modem, and wait about 2 minutes until all lights of your modem become solid on.

4) Wait another 1 or 2 minutes and check the internet access.

Step 6. Double check the internet connection type.

Confirm your internet connection type, which can be learned from the ISP.

Tips: You may visit whatismypublicip.com, you may check whether your IP address is public IP address or not.

Step 1. Your computer might not recognize any DNS server addresses. Please manually configure the DNS server.

1) Go to Advanced > Network > DHCP Server.

 2) Enter 8.8.8.8 as Primary DNS, click Save.

Tips: 8.8.8.8 is a safe and public DNS server operated by Google.

Step 2.  Restart the modem and the router.

1) Power off your modem and router, and leave them off for 1 minute.

2) Power on your router first, and wait about 2 minutes until it get a solid power.

3) Power on the modem, and wait about 2 minutes until all lights of your modem become solid on.

4) Wait another 1 or 2 minutes and check the internet access.
