Windows 7: Vista to Win7 - unidentified network

Vista to Win7 - unidentified network

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

Hello PeterQ, and welcome to Windows Seven Forums.

Thank you for listing what you have already tried, it will save time. It also tells us you have done some homework! Nice.

There was a missing registry entry in Vista that resulted in an all zeros MAC address, but that was corrected with 7, so unless you did an inplace upgrade from Vista to 7, it is not likely that applies. Please let us know how 7 was installed? "Clean" install? "In-place Upgrade"?

It would be helpful for us to be able to see your 'network' settings. There are several ways to do that. One way is to open a "elevated permission" command prompt (meaning right click on the command prompt icon and "Run as administrator"), then type: ipconfig /all

Then, right click inside the command prompt window and select "select all". Next press "Enter", then in the reply window where you are typing to us, you can paste the ipconfig. You can even edit out any personal info you do not want to appear.

We find pictures are worth a thousand words. Here are some links, if they are of help to you, on adding some to your posts:

Hi, iseeuu and thank you for the quick reply.

This was an "in place upgrade"

Unfortunaltely I cannot figure how to place any screenshots from my faulty computer as it has no connection anywhere. (unless I take an actual photo of the screen)
I'm writing from an old stationary I hooked up to the network. But I will try to neatly write down all the important aspect.

Ipconfig/all: (shows the ethernet card)

Windows ip configuration
hostname...................: Peter-PC
primary dns suffix........:
node type..................: hybrid
ip routing activated......: no
wins proxy activated....: no

Ethernet card local connection:

Description.......................: Broadcom Nextreme Gigabit Ethernet
Physical adress.................: 00-26-22-10.E2-7E
DHCP activated................: yes
Automatic config activated: yes
Automatic ipv4 adressconfig: 169.254.40.45 (preferred)
netmask.........................: 255.255.0.0
standard gateway............:
Netbios over tcpip............:Activated

Hope this comes out unscramled..

It seems to be a dhcp problem as I'm only getting an APIPA address...(?)

PeterQ;

In-place upgrades bring untold variables into your new computer system. I would suggest to you to use the "Easy Transfer Wizard" and save all you settings from the faulty computer, reinstall a fresh Windows 7, install any additional programs, and restore your settings with the Wizard.

You could attempt a repair install: Repair Install

When you posted that you had connected directly to your modem, I assumed you were able to connect to the Internet?

From your ipconfig: The "Standard Gateway" should be the address of the router, ie: 192.168.?.? and the IPV4 address should be the address assigned to the computer by the router, ie: 192.168.1.2 (or something like that).

NetBios is old technology. It is disabled on my system.

So your assessment is correct in that DHCP has not assigned and address to your computer, however neither has the computer asked for an address as it doesn't know where to ask (no Gateway).

I have my doubts that it would actually help, but you could try going to the 'network' properties, remove everything (the network card, TCIP, NetBIos, etc.) and reboot. Then add anything (except NetBios) that Windows does not automatically restore after the reboot?

Cheers!

Notice that you have no DNS server listed and the Gateway is blank. These entries should point to your ISP's servers... you ain't going anyplace without them.

Check in your network settings for TCPIP v4 ...
Is DHCP enabled for both IP and DNS?

In the advanced section...
Is "Register with DNS" checked?

In WINS settings...
Disable lmhosts lookup
Set Netbios on automatic

In the main panel be sure that client for Microsoft Networks is enabled.
Also be sure TCPIP v4 is enabled.

It shouldn't hurt anything if you disable TCPIP v6.. in fact my connections work better if I do.

Once all this is checked/done... reboot and see what happens. Click the network icon in the taskbar and you should see "Internet Access" if it's working.

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.

Thank you all for your help and contribution to this.. yet the problem still stands.
About the repair install. Do I need a full version of windows 7, or can I use the In place discs?
