Internet entirely unable to work

Lately, my computer has had trouble connecting to the internet. I'm completely unable to do any work I need to do, etc. This has gone on for 2 weeks. Occasionally, it will work for about 3 minutes but then stops working again. My computer is a desktop PC and not a laptop.

Here's what I've gathered from tampering with it:

  • My computer cannot connect to a wired or unwired connection (I think)

  • My computer does not display a yellow warning sign when it's unable to connect.

  • The main error I am receiving is 'server DNS address cannot be found'.

  • It says I am connected without any problems when I get the above error. When it says I am connected my browser and internet are not working.

So, I don't really know what to do because it says I'm connected. Though, I suppose this final point might help answers: other devices are able to connect completely fine.

Is there any way to fix my problem? Thanks.

Update:

My internet is now functional for about 5 minutes after I restart my computer. It then goes strange, and gives me a 'Server DNS Adress could not be found' error. The troubleshooter is not able to fix it. Does anyone have any ideas?


Solution 1:

Is there any way to fix my problem?

Try reinitialising the network states. Run the following commands in a cmd shell (you may need to be an Adminstrator).

  • Reset WINSOCK entries to installation defaults:

    netsh winsock reset catalog
    
  • Reset TCP/IP stack to installation defaults:

    netsh int ip reset reset.log
    
  • Reset Firewall to installation defaults:

    netsh advfirewall reset
    
  • Flush DNS resolver cache:

    ipconfig /flushdns
    
  • Renew DNS client registration and refresh DHCP leases:

    ipconfig /registerdns
    
  • Flush routing table (reboot required):

    route /f
