Device or resource (DNS server) is not responding, slow internet

[timothyhi]

Hi,

I'm new to this forum so please do excuse me if I'm posting this in the wrong area.

Anyway, my computer's been having some ridiculously slow internet speeds for the past few days and whenever I do a troubleshoot, it states that the 'device or resource (DNS server) is not responding'. I've tried every possible solution I read online and I'm still experiencing this problem.

I'd greatly appreciate any help given, thanks!

Which A/V software do you have installed?

Right now the only antivirus I have installed is microsoft security essentials.

Have you tried going into Device Manager and disable the Microsoft Virtual WiFi miniport adaptor?

This Virtual adaptor sometimes causes connection and DNS issues when it's activated. It's only used for creating a hosted wireless network.

Hmm, which device group is that under? Cause I can't seem to find it.

Do you have any VPN software installed on either system?

1 - You might try to uninstall the VPN software and reboot the box.
2 - In order to show hidden devices in Device Manager, open Device Manager, Choose View - Show Hidden Devices, disable the Microsoft Virtual WiFi miniport adaptor if you see it there.
3 - Delete any and all Intel networking components (actually you choose uninstall)
4 - Delete the Microsoft 6to4 Adapter (it will be remade on the reboot)
5 - Delete all the Microsoft ISATAP drivers.
Reboot, and let the OS detect and remake the network adapters, 6to4, and ISATAP drivers.
6 - Install the latest driver for your network adaptor.

Hi again, thanks for the reply, really do appreciate it.

Okay, so I followed your steps and only managed to find the Microsoft ISATAP drivers, three of them to be exact. I deleted them and when I rebooted the PC, my computer didn't re-install them, and the internet remained at the same speed. What should I do now?

Most likely there are problems other than the network interface involved here.

Have you tried running the sfc/scannow command from an elevated command prompt?

Hi,

I ran the sfc/scannow command and it told me that they conducted some repairs on my computer. However. I'm still experiencing slow internet, though it is slightly faster than before. What should I do now? Thanks.

From what you are saying here there are other problems with your machine besides just the network interface, the interface problem is just a symptom of other problems with your machine.

You might want to run a start up repair from the Windows CD.

You will want to run the start up repair three times in order to fix all problems.

If that doesn't work try the more drastic Repair Install.
