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.

Fix TP Link DNS Server not Responding:

Going by your query, it seems that you have not opted for automatic IP generation from your ISP via DHCP. The option for automatic IP address can be turned on from your router settings page which is fairly simple and easy. I will discuss how to complete it,

just follow the instructions given below carefully:

Step 1: Connect your router to your computer via 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 few seconds to let the connection between the two get established.

Step 2: Open your web browser and 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 and leave the password field blank and hit enter to get access to main settings of your router. In case your ISP has provided you any 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 automatic IP address from your ISP without you worrying about changing it every few months.

Hopefully, these steps helped you in getting your TP Link router dns server not responding problem resolved. In case you have any further doubts or problem, feel free to reply and I will be glad to help.

To connect WiFi devices in my home, I've been using a TP-LINK TL-WR740N 150Mbps Wireless N Router. It has been operating without any issues for a few months now. After returning from a seven-day vacation, I discovered that my,tp-link dns not router was having issues, such as being unable to resolve the DNS server whenever I tried to access any websites.

I initially believed my Internet Service Provider (ISP) was the issue. To resolve this, I called my ISP, BSNL. When the officer arrived at my house to investigate, he informed me that everything was OK and that there was no issue on our end.

At first, he believed there might be an issue with my modem (don't mix it with a router). We also replaced the modem, but the issue still exists. He, therefore, surmised that my router itself might be having problems. This time, we established a wired connection between my desktop and the LAN ports from the modem. This time, I saw no issues with my desktop computer being unable to connect to the internet via my TP-Link router.

Thus, we deduced that my Tp link DNS server not responding. After the police left, I got to work resolving this.

What Did I Use?

Desktop: The internet functions appropriately on my desktop. It is directly connected from the modem via a LAN cable (wired connection), not via a TP-Link router. I'm not having any issues at all.

Laptop: Here, I'm connecting to the internet utilizing WiFi signals from my TP-link router. I need help with using this device here.

What Issue is it that I have with my TP-Link router?

Whenever I try to reload or refresh a webpage, the websites I try to view initially won't open. It will open with no issues. It is a regular disconnect from the internet.

All websites have a prolonged response time, or at least that's what I experienced when I tried to access any of them. You can notice this by looking at the "Looking for or Resolving." notifications beneath the browser. Using the desktop to verify it nearly takes 30 to 40 seconds instead of 2 to 5 seconds.

When you browse any website, occasionally you'll see faulty or incorrectly loading pictures, as well as a message similar to "Unable resolve DNS." on a widget.

These are the issues I ran into when using my TP-Link router to connect to the internet via WiFi (LAN cable testing was not done).

How Can TP-Link Routers' DNS Server Address Be Changed?

While connected to a WiFi network, visit http://tplinklogin.net/ or to modify the DNS servers' IP address on the TP-Link router setup.

Primary and Secondary DNS are displayed here. In my situation, both have been set to the default value of

After making the necessary changes, I clicked the save button. I now have the values I had on my desktop computer, which are and If you need to learn DNS, contact your ISP; they can assist you. It will now prompt you to restart it.
