Issues with DNS server responsiveness - No internet access

First off, apologies for asking a question which has been asked numerous times, however I have tried almost all of the suggested fixes to the issue, and the issue is still there.

I have tried the common fixes, such as resetting the router, uninstalling the network adapter drivers, flushing the DNS in the command prompt, resetting the log, switching between automatic and manual DNS servers - using recommended public servers.

Is there anything else that you guys can suggest I do? I have now been without any access to internet since Wednesday. When I attempt to connect to my phones wifi (personal hotspot) i have no issues.

Thanks in advance

so nothing via the router?

can your phone / tablet / TV connect to the net via your router?

tried :

changing filter

router in Master socket

another router

Hi, thanks for your speedy response. My phone connects to the net flawlessly, and it seems all of my flatmates are relatively issue free too. Which is making me think it is definitely an issue with my laptop.

Because your problem started so very recently, have you tried a System Restore? If you haven't and don't know how to do it then have a read here (for Windows 7). Note that you won't lose any personal data (such as emails, documents, photos, music, etc) and that you can undo the restore if it doesn't help or creates unexpected issues.

I tried completely disabling my firewall, and that seemed to have no affect, and i have also seen that security software is causing this issue for others, however I took the steps they all did to find that it either had no affect or that the issue they had wasn't there in the first place. I wouldn't be able to tell you my internet provider to be honest, however i doubt it being a uni wide internet that it is Virgin.

I went to perform a system restore, to find that the only restore point was yesterday, when I was updating drivers and such, i had the issues at this point so i doubt restoring would be much use, thanks for the advice though.

".......the only restore point was yesterday...."

Did you tick the box to "Show other restore points"? If you did then let's abandon that idea.

What makes you believe it's a DNS issue?

It may help if you paste the output from ipconfig /all here while connected to the router/WiFi hotspot that you normally use.

Do you get the same problem with wireless and Ethernet connections or are unable to use the latter?

It may also be helpful if you booted into "Safe Mode with Networking" for a while. If the Internet works fine there then we know it's not a Windows/drivers problem but a third-party program that runs in Normal mode is interfering with things.

Yes, it was the only restore point available.

The only reason I believe it is a DNS issue is due to the fact that whenever i troubleshoot the connection the only issue is the 'The DNS server isn't responding' error.

I am unable to use an Ethernet connection, guess the uni just assumed everyone had wifi.

I have tried booting in safe mode, and I still had no internet access, I obviously couldn't then trouble shoot to determine whether it was still the same error message, due to me being in safe mode.

When i use ipconfig /all, this is what is spews out:

C:\WINDOWS\system32>ipconfig /all

"..........I have tried booting in safe mode, and I still had no internet access"*

You'll only get Internet access with "Safe Mode with Networking". If that's what you tried then it sounds like a Windows problem.

To get a better idea of what's going on, type ping www.google.com into a Command Prompt window and paste the output here.

Your IP config details look fine - all the IP addresses look correct including the DNS server.

.............and please reply with your Windows version too.

  MGEdwards 19:51 25 Jan 15

Yeah, I'm pretty confident i activated networking, however I'll try once more.

When i ping,

C:\WINDOWS\system32>ping www.google.com Ping request could not find host www.google.com. Please check the name and try a gain.

I'll quickly try the safe mode once more.

  MGEdwards 20:17 25 Jan 15

Apologies, didn't see your second message. I am running Windows 8.1.

I tried the safe mode again, and had no success
