The situation when, when connecting via a wireless network, the browser displays the error “DNS server is not responding” is familiar to many users. Windows 10This means that your computer cannot resolve the website's domain name to its IP address, preventing internet access even though the WiFi connection is technically established.
This behavior can be caused by software glitches in the operating system, incorrect router or ISP settings, or other issues. Often, the problem stems from a backlog of DNS cache, a network adapter driver conflict, or temporary unavailability of the service provider's servers.
In this guide, we'll cover all the effective troubleshooting methods. You'll learn how to diagnose the problem, change system settings, and use hidden utilities. Windows to restore stable network operation without having to reinstall the system.
Primary diagnostics and equipment testing
Before delving into complex system settings, it's important to rule out simple hardware failures. Often, the error is caused by a temporary freeze of the WiFi module in the router or the laptop itself. Restarting the hardware allows you to clear the memory buffers and re-validate the connection with the ISP.
Pay attention to the wireless indicators. If the WiFi icon shows a network but no internet access (an exclamation point), the problem is most likely software-related. If no network is found or the status is "No connections," check the physical WiFi switch on the device.
It's also worth checking whether the internet is working on other devices connected to the same access point. If the problem only occurs on one computer, then the issue is with its settings. If the entire network is down, it's possible that your provider is undergoing maintenance.
⚠️ Caution: If you're using a USB WiFi adapter, try moving it to a different port. Insufficient power to one of the ports can cause unstable operation and DNS errors.
Changing DNS servers to public addresses
The most common and effective solution is to replace automatically obtained DNS addresses with stable public servers from Google or CloudflareProviders often provide slow or overloaded name servers that stop responding during peak hours.
To perform the replacement, go to Control Panel → Network and Internet → Network and Sharing CenterIn the left pane, select "Change adapter settings," find your wireless connection, right-click, and select "Properties." Find and open the properties in the list of protocols. Internet Protocol version 4 (TCP/IPv4).
☑️ Check IP settings
In the window that opens, select the "Use the following DNS server addresses" option and enter the following values:
- 🌐 Preferred DNS:
8.8.8.8(Google) or1.1.1.1(Cloudflare) - 🌐 Alternative DNS:
8.8.4.4(Google) or1.0.0.1(Cloudflare) - 📝 Be sure to check the box "Verify settings on exit"
- 🔄 Click "OK" and close all windows
After applying the settings, you need to refresh your connection. Disconnect and reconnect your WiFi. The system will attempt to request addresses through the new gateways, which often resolves the issue immediately.
Clearing DNS cache and resetting network settings
operating system Windows 10 Stores a table of domain and IP address mappings in a local cache. If this cache accumulates invalid or outdated entries, the browser will receive incorrect data or not receive it at all, generating an error.
To force clear the cache and reset the TCP/IP stack, use the command line. Click Win + R, enter cmd and press Enter. In the black console window, you must enter a series of commands sequentially, confirming each one with the Enter key.
ipconfig /flushdnsipconfig /registerdns
ipconfig /release
ipconfig /renew
netsh winsock reset
After executing the last command netsh winsock reset The system will notify you that a reboot is necessary. Ignoring the reboot after resetting Winsock will render all previous actions useless., since the changes take effect only after restarting network services.
| Team | Function | Need to reboot |
|---|---|---|
flushdns |
Clearing the DNS cache | No |
registerdns |
Renewing DHCP and re-registering DNS | No |
release / renew |
Resetting and obtaining a new IP address | No |
netsh winsock reset |
Resetting the Winsock catalog | Yes |
Updating and reinstalling WiFi drivers
Outdated or corrupted network adapter drivers are a common cause of unstable operation in Windows 10. This is especially true after major system updates, when older adapter software no longer interacts correctly with new network protocols.
Open Device Manager from the Start menu (right-click the Start button). Find the Network Adapters section and expand it. Find the device with a name containing Wireless, WiFi or 802.11Right-click and select "Uninstall device".
What to do if the driver is not found in the list?
If Device Manager shows unknown devices with a yellow exclamation mark, the WiFi driver may be completely corrupted. In this case, download the driver installer from the official website of the laptop or adapter manufacturer on another device and transfer it via USB flash drive.
Don't be afraid to remove the device - after reboot Windows will automatically detect the hardware and attempt to reinstall the driver. If automatic installation doesn't help, download the latest version from the manufacturer's website (for example, Realtek, Intel, Qualcomm Atheros) and install manually.
⚠️ Note: When uninstalling a driver, the confirmation window may check "Delete the driver software for this device." If you don't have the driver installation file handy, it's best to leave this checkbox unchecked to ensure the system retains the default version.
Disabling antivirus and firewall
Third-party antivirus programs and built-in firewall Windows Defender They may mistakenly block DNS requests, considering them suspicious activity. This often happens after virus signature database updates or when the security module malfunctions.
Try temporarily disabling real-time protection in your antivirus settings. If you are using a third-party product (Kaspersky, ESET, Dr.Web), find the "Network" or "Security" option in its interface and pause it for 10-15 minutes. Check the availability of websites.
- 🛡️ Open Windows Security Center (the shield icon in the tray).
- 🛡️ Go to the "Firewall and network protection" section.
- 🛡️ Temporarily disable the firewall for both private and public networks.
- 🛡️ Check your internet connection.
If the internet works after disabling protection, the problem lies in the filtering settings. Don't leave your computer unprotected for long. It's best to add your browser to the exceptions list or perform a clean reinstallation of your antivirus.
Using a network diagnostic utility
IN Windows 10 A powerful automatic troubleshooting tool is built in that can automatically detect and fix a range of configuration errors, including resetting network components.
Search the Start menu and type "Network Diagnostics." Run the resulting tool as an administrator. The system will run a series of tests, checking for a connection to the gateway and attempting to receive a DNS response. If any issues are detected, the wizard will offer to fix them.
An alternative way to run deep diagnostics: go to Settings → Update & Security → DiagnosticsHere you can launch "Internet Connection Sharing" or "Network Adapter." The tool will attempt to reset the adapter and update the configuration automatically.
Why doesn't the diagnostic find any errors?
Built-in Windows tools often perform only superficially. If the diagnostic wizard says "No problems found" but the internet still isn't working, the problem lies with apps or your ISP, not with the underlying OS settings.
FAQ: Frequently Asked Questions
Why does the error only appear in the browser, while other applications work?
This indicates a problem with your browser settings or extensions. Check if a proxy server is enabled in your browser settings and try disabling all extensions, especially VPNs and ad blockers.
Can a virus cause the DNS server not responding error?
Yes, some malware changes the system file. hosts or DNS settings to redirect traffic to phishing sites. Check the file. C:\Windows\System32\drivers\etc\hosts for the presence of extra entries.
What to do if nothing helps?
If all software solutions have failed, the problem may be with your ISP or router. Try a full reset of the router (press the Reset button) or contact your ISP's technical support to check the line.
Does time and date affect DNS errors?
Yes, an incorrect system time can cause security certificate errors and problems connecting to secure DNS servers. Make sure the date and time are correct. Windows synchronized with the Internet.
