How to Resolve DNS Issue in TP Link Router

I have been using TP-Link TL-WR740N Wireless Router in my Home to connect Wi-Fi devices. It is working fine for few months without any problem. I went on vacation for 7 days and when I back I noticed that my TP-Link router starting showing unable to resolve DNS Server when I tried to browse any websites. Initially, I thought it is problem with my Internet Service Provider (ISP). So I contacted my ISP (BSNL) to fix this problem. But the settings are fine, and now I am unable to fix this problem. Please, help me how to fix this issue.

Just follow the instructions given below carefully:

Step 1: Connect your router to your computer via an ethernet cable. One end of this cable goes inside the LAN port of your router while the other end goes inside the ethernet port on your computer.

The ADSL cable goes into the WAN port of your router. once the set-up is complete, wait for a few seconds to let the connection between the two get established.

Step 2: Open your web browser type in in the given URL field and hit Enter. This will redirect you to the login portal of your router.

Step 3: Enter "admin" in the username field leave the password field blank and hit enter to get access to the main settings of your router. In case your ISP has provided you an SSID & password, enter those credentials.

Step 4: Once on the main settings page, go to DHCP settings or WAN settings whichever of the two is available. In the DHCP/WAN settings tab, you will notice a box for DHCP settings, choose YES.

This will provide your TP-Link router with an automatic IP address from your ISP without you worrying about changing it every few months.
