1. Check your antivirus
If you are having problems with the network, the first thing to check is your antivirus software.
If you’re using Windows 10, you’ll still be protected by Windows Defender even if you choose to remove your third-party antivirus, so you don’t have to worry about your security.
If removing your antivirus solves the problem, now might be the perfect time to switch to a different antivirus.
If you want reliable protection that won’t interfere with your system, we recommend that you consider Bitdefender Antivirus Plus.
This is not a simple antivirus, but a real security solution.
This is because Bitdefender Antivirus Plus not only guarantees live protection against malware, Trojan horses, worms and more, but also includes Social Media Protection, Secure Online Banking and Password Manager systems.
It even comes with a built-in VPN so your online privacy can be protected at all times by routing your traffic through secure servers.
But above all, the Bitdefender solution will not interfere with your DNS server or settings like other antivirus solutions.

- Click the network icon on your taskbar and select your network connection from the menu.
2. In the right pane, click Change adapter options.
3. Right click on your network connection and choose Properties from the menu.
4. Select Internet Protocol Version 4 (TCP/IPv4) and click the Properties button.
Select Use the following DNS server addresses and set the following values: Preferred DNS server: 8.8.8 and Alternate DNS server: 8.4.4
5. Click the OK button to save the changes.

3. Use a VPN
According to users, if the DNS server is not accessible, you may be able to solve the problem using a VPN. You will get a new IP address and your privacy will be protected while surfing the web.
Even if you don’t have this problem, having a good VPN is a great way to protect your privacy online.
There are many services available, but if you are looking for a good and reliable VPN, give private internet access a try.
First of all, this software protects your privacy, even from your ISP, and allows you to use public Wi-Fi networks without worrying about threats.
Having a different IP address will unblock a lot of new content from video-on-demand platforms such as Netflix, HBO GO, Amazon Prime Video, and others.
Best of all, private Internet access offers the fastest speeds, so be prepared for seamless, buffer-free streaming.
4. Use Command Prompt

2.Run these commands:
- ipconfig /flushdns
- ipconfig / registerdns

7. Try using a different device to access the Internet
If the DNS server is not accessible, the problem could be your PC settings. To determine if the problem is just your PC, it is recommended that you test other devices and see if they can access the Internet.
For best results, it is recommended to use a different Windows PC, but you can also use your phone or another device.
If other devices can connect to the Internet, the problem is probably related to your PC and its settings, so you can focus on solving the problem.
8. Try restarting your router
If this problem persists, the problem may be with your router. To fix the issue, users suggest restarting their router/modem and check if that helps.
This is quite easy to do and to do it just press the power button on your modem/router to turn it off.
Now wait about 30 seconds and press the power button again to start your modem or router. Wait while the device boots up completely and check if the problem persists.
