Vista to Win7 - unidentified network

This morning I did a clean install, and to my great relief my internet is up and running again. Thank you. Case solved.

Excellent! We are all glad you got it sorted out. I know a clean install, while more effort and time, will save untold headaches in the future. Thanks for letting us know all is well.

Happy surfing!

Hi,
This is my third day struggelig with this problem. I've searched around and realize there are many with the same issue.
Ever since I migrated to windows 7, I can not get my laptop to connect to the internet.

The error message is "Unidentified network" and when I perform a diagnosis is says "Local connection does not have a valid IP configuration".

I think I've tried it all with no luck so far.

I connect directly to the modem with cable. I also have dug up an old stationary machine to work with and connected it to the very same network with no problems.

This is what I've tried:

*Ensure Ip adress and dns are received automatic
*Restart modem, reset button, and restart pc, swithed cables
*Tried the rebuild ip stack and winsock commands
*Checked for the Bonjour program interferrence (don't have it)
*typed in ip adress and dns manually
*deactivate ipv6
*checked the "do not identify network" option
*update nic driver
*Tried to see if wireless connection works (it doesn't)
*typed in the real mac adress.. and then a fake one
*getting ip adress from another router.
*turn off firewall, disable antivirus.

Is there a solution to this except reinstalling an old OS?

The old vista was 32bit and so was the Win7 upgrade kit.

I've read about a possible solution which is to enter a registry key to force dns
registration, but I don't really grasp it.

I'm getting desperate and yet more determined to find a solution to this.
What I'm really hoping for is for someone to say "Yes this problem was fixed, just do this and that.. "

Thank you

It may help to reset Winsock for windows 7. This has fixed the same no browser access problem after upgrade from vista problem before.


1. Click start, type cmd in the Start Search box, right-click cmd.exe, click Run as administrator, and then press Continue.


2. Type netsh winsock reset at the command prompt, and then press ENTER.

Note If the command is typed incorrectly, you will receive an error message. Type the command again. When the command is completed successfully, a confirmation appears, followed by a new command prompt. Then, go to step 3.


3. Type exit, and then press ENTER. You should be prompted to reboot, if not you should reboot and test.

Here is link to my last post which fixed the problem perfectly.

internet connection present, but no browser works.

If you had followed the advice in my post above the problem would have been fixed. :)

Resetting Winsock was one of the first things I did. It had no effect on my problem.
I think a totall whipeout was needed on this one:)
