Security or firewall settings might be blocking the connection in Windows 10

Outgoing connections can be affected by the presence of firewall or antivirus software on the local computer or network connection. Windows comes with a built-in Internet Firewall that is active by default and blocks all FTP traffic. You can turn off this firewall (not recommended by Microsoft) or configure it to allow connections via CuteFTP. Configure your firewall so that ports 20 and 21 are open (not blocked). It may also be necessary to grant specific permission for CuteFTP to access those ports.

Follow the steps below to add CuteFTP to the Windows Firewall exceptions list.

To add CuteFTP to the Windows Firewall exceptions list

1. In the Windows Control Panel, double-click Security Center, then click Windows Firewall.

2. On the General tab, ensure Windows Firewall is On and then clear the Don't allow exceptions check box.

3. On the Exceptions tab, review the Programs and Services list to determine if CuteFTP is listed. Look for:

   • CuteFTP (the interface)

   • ftpte.exe (the Transfer Engine)

   Both programs must be shown in the list of exceptions. If they are not, then follow the steps below to add either one or both programs to the list.

4. Click Add Program. The Add a Program dialog box appears.

5. In the Programs list, click CuteFTP, then click OK. The Add a Program dialog box closes.

6. Click Add Program. The Add a Program dialog box appears.

7. Click Browse to navigate to the CuteFTP installation folder (by default in C:\Program Files\Globalscape), click ftpte.exe, then click Open.

8. Click OK to close the Add a Program dialog box and save your changes.

9. Verify both programs appear in the Programs and Services list, then click OK to exit Windows Firewall. The firewall will now ignore the transfer engine and the interface.

For more information about the Windows Firewall, see the article on Microsoft's website at http://www.microsoft.com/windowsxp/using/security/internet/sp2_wfintro.mspx, or search the Internet for "Windows Firewall."

So this morning when I when I tried to start my pc from sleep mode, I noticed the monitor (Dell SE2219HX) wasn't working for reasons unknown but everything else was working just fine.

The blinking white light on the display button wasn't there and the monitor was unresponsive. So switching off the power cable, I removed all the cords connected to the monitor and then reconnected and after powering up, it started working as usual.

But now, I can't connect to the internet. When I try to troubleshoot the problem the picture below shows up.

Windows can't communicate with the device or resource (primary DNS server)

Security or firewall settings might be blocking the connection.

Naturally, I watched some videos regarding this, but none of them seems to work for me. 

My wi-fi is working fine as I could connect to it through other devices. I don't have any third party antivirus installed in my computer.

I have tried turning the firewall off and on.

Tried powering off and restarting my router.

Tried removing and plugging the cable which is connected to the computer from the router.

Tried connecting through an android and then an ethernet cable via a laptop.

So far nothing worked. HEEEEELP!!

Making routine backup images of your partitions/drives...using 3d-party software...is probably the most important activity that any user can engage in.

Under Configure of the properties of the network adapter, then the Power management,  is the "Allow the computer to  turn off this device to save power" enabled. If so then uncheck.

Ok, First of all, many thanks for replying.

I have tried every 6 solutions written here (https://appuals.com/fix-windows-cant-communicate-device-resource-primary-dns-server/) as suggested by @hamluis and also unchecked the "Allow the computer to turn this device off to save power" as suggested by @0lds0d.

But it still ain't working unfortunately.

Though when I tried all these, after restarting the pc, the network button on the right side panel of the taskbar would show that I am connected for a little amount of time. If I hovered my mouse over that it would say 'internet access' but after some seconds it would go away again and 'no internet access' is shown.

I'm going crazy over this. If you guys have any other suggestions, plz let me know.
