Windows 7: How can I stop my DNS problems?

22 Mar 2012   #11

Windows 7 64

would it be the Realtek PCIe FE Family Controller that I reinstall? I'm using Google Chrome right now, but I could try Firefox

I would try IE9 or Firefox to see if the problem persists.

You want to reinstall the Network controller you are using to connect now, wired (Ethernet) or Wireless.

Alright...I reinstalled the driver and started using IE. I would say my connection is BETTER, but still not the same. I still can't do any downloading, or watch youtube videos. They won't load. My browser is still way too slow...

Make sure you have IE9. Reset it to defaults: Troubleshooting Internet Explorer Issues - Windows 7 Forums

Now reinstall Flash Player to see if problems continue.

Flush DNS again.

Next try Firefox to eliminate browser as the cause of this.

Windows 7 Premium x64
Same problem, how I fixed

I know this is an old thread, but in case anyone else found it looking for an answer, here's what I did to fix the same problem.
First, even though I was logged in as admin, I could not see the Microsoft Virtual WiFi Miniport Adapter. But, when I uninstalled the Realtech controller, the Microsoft Virtual WiFi Miniport Adapter showed up like magic. (remember to click "view" and "show hidden devices" in device manager.
I let windows reinstall the Realtech controller but could still see the Virtual Adapter. I disabled it, and ran ipconfig again. One of the tunnels was gone, but there were still more. I disabled any ISATAP adapters I saw, and there was still one more tunnel. I disabled the Teredo Tunneling Pseudo-Interface and that removed the last tunnel listed in ipconfig. I also disabled the Microsoft 6to4 Adapter, but I can't remember if that got rid of any tunnels, but it didn't seem to hurt anything.
The only connection now showing under ipconfig is my wireless connection.
I was having a problem with webpages loading very slowly (in Chrome), and could see "resolving host" in the lower corner. Windows wizard told me that my network adapter was configured correctly, but there was a problem with the DNS servers. I had flushed the dns cache, etc., all the other stuff, and nothing had worked. But after disabling the tunnels listed above, my internet is back to running like it should.
Hope this helps someone else, because it took me most of a day to figure it out. Thankfully, this thread gave me the clues to solve the problem.
