Windows 7: Messed up network settings

I have a Vodafone dongle that I use for internet connectivity, somewhere I did something to the laptops network settings and it cant connect. It's like it clashes wth a network or something. Is there a way to reset ALL the network settings to their original state? Please, someone, HELP.

Yes there is a way to reset the network stack, flush the DNS, release/renew the IP and reset winsock. You can just save the file below, unzip the file and run it until you machine reboots which will be automatic.

If you are still having problems please post a screen shot of your ipconfig/all and I will have a look at it.

Thanx Chev.... at last I can connect on my pc and not just the Ipad!!! can't tell you how much I appreciate it.

Good deal Max, it must have just needed a complete reset which is fairly typical problem.

Hi I was wondering if someone could please help me. A few weeks ago, I searched for ways to speed up Windows 7 and IE. I came across a web page which stated to change binary values in Regedit and running cmd as an administrator and change teredo etc (I can't exactly remember all the settings and cannot find the original web page).
I made the changes and for sure my computer is running faster and so is IE10. But now, when I try and download from utorrent, my Internet goes out and I have to restart. Opening uTorrent automatically disables my Internet instantly.
At first I thought I might have a virus but I ran Malwarebytes, MSE, Norton, and several other anti virus programs and nothing was detected. I think changing my settings in Regedit and also running the cmd prompt and changing the Toredo settings etc is the problem. Can someone help in changing all to default settings? Thank you, Steve
My computer is currently running a 64 bit Windows 7 Ultimate and I have IE10 installed.
In the cmd prompt for c:\Windows\system32>netsh interface teredo show state Teredo Parameters I have:
Type: disabled
Server Name: teredo.ipv6.microsoft.com.
Clinet Refresh Interval: 30 seconds
Clinet Port: unspecified
State: offline
Error: none
Thank you!
