Why Does My WIFI Say No DNS Server Available?


Heather Bennett

Are you experiencing the frustrating message “No DNS Server Available” when trying to connect to your Wi-Fi network? Don’t worry, you’re not alone! This issue can occur for various reasons, but thankfully, it can usually be resolved with a few simple steps.

What is a DNS Server?

Before we delve into the reasons for the “No DNS Server Available” error, let’s first understand what a DNS server is. DNS stands for Domain Name System, and it acts as a directory for the internet. When you type a website URL into your browser, the DNS server translates that URL into a numerical IP address that computers can understand.

Reasons for the “No DNS Server Available” Error

There are several possible causes for this error message. Let’s explore some of the most common ones:

  • Router Issues: Sometimes, the problem lies with your router. It could be due to outdated firmware or misconfigured settings. Restarting your router or updating its firmware might resolve the issue.
  • DNS Cache: Your computer may have stored incorrect or outdated information in its DNS cache. Flushing the DNS cache can often fix this problem.

    To do this, open the command prompt and type “ipconfig /flushdns“.

  • Incorrect Network Settings: It’s possible that your network settings are improperly configured. Ensure that your computer is set to obtain both IP and DNS addresses automatically.
  • DNS Server Problems: The issue may lie with your Internet Service Provider’s (ISP) DNS server itself. In such cases, contacting your ISP’s technical support can help resolve the problem.

Troubleshooting Steps

Now that we understand the possible causes, let’s go through some troubleshooting steps:

Step 1: Restart Your Router

If the problem is due to router issues, a simple restart can often do the trick. Unplug your router from the power source, wait for a few seconds, and then plug it back in. This will refresh the router’s settings and can resolve any temporary glitches.

Step 2: Update Router Firmware

If you haven’t updated your router’s firmware in a while, it’s worth checking if there are any new updates available. Visit your router manufacturer’s website and follow their instructions to update the firmware. This process varies depending on the brand and model of your router.

Step 3: Flush DNS Cache

To flush your DNS cache, open the command prompt on your computer and type “ipconfig /flushdns“. This command will clear any incorrect or outdated entries from your DNS cache.

Step 4: Check Network Settings

Ensure that your computer is set to obtain IP and DNS addresses automatically. To do this:

  1. Go to Control Panel > Network and Internet > Network Connections.
  2. Right-click on your active network connection and select “Properties”.
  3. In the Properties window, double-click on “Internet Protocol Version 4 (TCP/IPv4)”.
  4. Select “Obtain an IP address automatically” and “Obtain DNS server address automatically”.
  5. Click “OK” to save the changes.

Step 5: Contact Your ISP

If none of the above steps resolve the issue, it’s possible that the problem lies with your ISP’s DNS server. Contact their technical support and provide them with details about the error message you’re encountering. They will be able to guide you further and help resolve the issue.

By following these troubleshooting steps, you should be able to fix the “No DNS Server Available” error and get back online in no time!

Remember, Wi-Fi issues can be frustrating, but with a little patience and persistence, they can usually be resolved. Happy browsing!
