Understanding DNS
Before diving into the specifics of router DNS issues, it’s essential to understand what DNS is and its role in internet connectivity.
What is DNS?
DNS, or Domain Name System, can be likened to the phonebook of the internet. It’s a system that translates human-friendly website names, like www.google.com, into numerical IP addresses that computers use to communicate with each other.
When you type a website address into your browser, your computer uses DNS to retrieve the IP address of that website. It then uses this IP address to locate and connect to the website. DNS is an integral part of how the internet works, and without it, we would have to remember the IP addresses of every website we want to visit.
Role of DNS in Internet Connectivity
The role of DNS extends beyond just translating names to IP addresses. It’s also crucial for maintaining the health and efficiency of internet connections.
Every time you connect to a new website, your computer sends a request to a DNS server. This server looks up the IP address corresponding to the website name and sends it back to your computer. This process, known as DNS resolution, is what allows your computer to establish a connection with the website server.
If the DNS server fails to respond or responds incorrectly, this can lead to connection problems. These are often referred to as DNS issues, and they can manifest in various ways, such as websites not loading or loading incorrectly.
Understanding DNS is the first step towards understanding and resolving router DNS issues.

Recognizing Router DNS Issues
Being able to recognize the signs of router DNS issues can save you from a lot of inconveniences and frustrations. The first step towards solving these issues is understanding their common symptoms and how they can affect your internet connection.
Common Symptoms of DNS Issues
DNS issues often manifest in several ways that can disrupt your online activities. Some of the most common symptoms include:
- Slow browsing speeds: If your internet connection is slower than usual, it could be a sign of DNS issues. This is because the DNS server might be taking a long time to translate website names into IP addresses.
- Website loading errors: If you’re having trouble accessing websites and receiving error messages like “DNS server not responding” or “page not found”, it’s likely you’re dealing with DNS problems.
- Inconsistent connectivity: If your internet connection is unstable, dropping out intermittently, a faulty DNS could be the culprit.
- Inability to connect to certain sites: If you can access some websites but not others, it might indicate that your DNS server has issues resolving the addresses of the inaccessible sites.
How DNS Issues Affect Your Connection
DNS issues can have a significant impact on your internet connection. The DNS (Domain Name System) is responsible for translating website names into IP addresses. Therefore, if the DNS server is experiencing problems, your device might struggle to connect to websites, leading to slow browsing speeds or even complete loss of connection.
When the DNS server fails to resolve website names correctly, you might be unable to access certain websites. This can be particularly frustrating if you need to access these sites for work or personal use.
Moreover, DNS issues can also lead to inconsistent internet connectivity. You might find your internet connection dropping out at random times, which can disrupt your online activities and productivity.
If you’re experiencing any of the above symptoms, it’s possible that you’re dealing with router DNS issues. In such cases, you might need to take steps to resolve these issues, which can range from simple troubleshooting measures like restarting your router to more advanced steps such as updating your router’s firmware or changing its DNS server settings. For more information on how to troubleshoot these issues, check out our guide on troubleshooting router issues.
Basic Troubleshooting Steps
When experiencing router DNS issues, there are a few basic troubleshooting steps you can take to resolve the problem before resorting to more advanced methods. These include restarting your router, checking your internet connection, and verifying the DNS server address.
Restarting Your Router
The first and often most effective step in troubleshooting router DNS issues is to restart your router. A simple restart can clear out any temporary issues or bugs that may be affecting the router’s functionality.
Here’s how you can do it:
- Unplug your router from the power source.
- Wait for about 30 seconds to a minute.
- Plug the router back into the power source.
- Wait for the router to fully reboot and check if the issue has been resolved.
If you’re still experiencing issues after a restart, you might need to perform a full reset of your router. However, this should be a last resort as it will erase all of your current settings.
Checking Your Internet Connection
The next step is to check if the problem lies with your internet connection. If you’re unable to connect to the internet at all, the issue might not be with the DNS but rather with the connection itself.
Try visiting several different websites to see if the issue is limited to certain sites. If you’re unable to connect to any websites, you might be dealing with an internet outage. In this case, you should contact your internet service provider for further assistance.
If the problem is only with specific websites, it’s likely a DNS issue. For more information on troubleshooting internet connection issues, check out our guide on router not connecting to internet.
Checking DNS Server Address
If you’ve confirmed that your internet connection is working, the next step is to check your DNS server address. Incorrect DNS settings can lead to connectivity problems.
To check your DNS settings:
- Open your router’s configuration page. This is usually accessed by typing a specific IP address into your browser’s address bar.
- Look for the DNS settings. These are typically located in the ‘Internet’ or ‘WAN’ section.
- Check that the DNS server addresses are correct. If you’re unsure what they should be, you can use the free DNS servers provided by Google (8.8.8.8 and 8.8.4.4).
If the DNS server addresses are incorrect or empty, this could be causing your connectivity problems. In that case, you might need to manually enter the correct DNS server addresses.
Remember, while these basic troubleshooting steps can resolve many common router DNS issues, they may not work for more complex problems. If you’re still experiencing issues after trying these steps, it might be time to move on to more advanced troubleshooting methods.
