Windows 7 - Unidentified Network

Last response: in Networking

February 23, 2010 6:04:31 PM

Hi,

I have been reformatting several computers to upgrade to Windows 7 at my work and have encountered a problem on 2 of the PCs.

On these 2 PCs, each time I turn off/on computer I won't have internet access, and I have a second network named "Unidentified Network". I can't find any way of getting rid of the second "phantom network" unless I disable the network LAN adapter and then re-enable it. Once doing that, the Unidentified Network goes away and I will have internet access again.

If I run the Troubleshoot, Windows 7 DOES find the problem, but always fails to fix the multiple network issue. I have tried uninstalling the network adapter several times and still no fix. There is only 1 network adapter on both PCs. I have tried researching fixes and I have found people saying this is a Windows 7 bug and there are no true fixes, and some people have said to just reformat.

Any input?

Have you tried changing the network setting to either private or home network? Can't remember which one it is. At work right now.

Yes I've tried that.

I may have found a fix but haven't tested it yet. I learned about a program called Bonjour (part of the Adobe Suite) causing network problems after being installed. And now that I think about it, if that truely is the problem, it did start sometime after I installed Adobe Suite.

The fixes say to either remove Bonjour, or there is an update that will fix the network issue. I will be trying it tomorrow. Hopefully it will work!

The network issue occurs on and off. Sometimes at start up the network will have just my own homegroup and internet will work fine. Other times the unidentified network shows up and I have to reset LAN adapter in order to have it go away in order to make internet work.

No Internet, but what about the Intranet? Can they see the servers and access network shares?

When the unidentifed network is present, the network places shows as "Multiple Networks" and you can still click on it and see the office computers. No unknown computers there, all are present and accounted for.

Therefore the computer should also have access to the Internet. If it doesn't, then routing is incorrect. Did you check it with route print?

The computers do have access to the internet, but there is limited connectivity and you cannot actually login to the internet (ie internet browser). It only happens on 2 of the computers that were just reformatted.

You got me confused. Users normally don't login to the Internet. Can you explain what you mean? In an office environment, users normally have a domain login account and it will work as long as the system has joined the domain (an IT admin task that's required after reinstalling the OS).

Ngwylie,

Have you attempted to remove the device and then reinstall it to see if that will remove the "phantom network"? Also, Microsoft does have an official Windows 7 Support Forum located here: http://social.technet.microsoft.com/Forums/en-US/catego.... It is supported by product specialists as well as engineers and support teams. You may want to also check the threads available there for additional assistance and guidance.

Sorry for not getting back to this thread. I seemed to have fixed it by creating static IPs to each computer in the office... It's been working fine for the past couple days.

I meant logging onto the internet by simply clicking on internet explorer and getting a page to display, and also having to get rid of the limited connectivity.

I don't think I mentioned this previously, but Windows 7 is able to identify the problem with the network, BUT, when you try to Repair it, it will just error every time, it is unable to get rid of the unidentified network. I just set every computer to an assigned internal IP and they are all connecting to the same network fine now, no phantom network.

I really dont know anything about this but I got this problem before. I just disabled any of the two networks(i disabled the unidentified one) when the unidentified network shows. Then I use the troubleshoot thingy for the network and *poof* its all fixed. I noticed that it shows when my pc is not shutdown properly or when there and error during shutdown.

I got tired of doing this manually so i googled the problem and i found a fix. But now its back coz i reinstalled my win7 and im too lazy to google it again :D 

'twas something like ' delete route' or something.

What do you mean by disabling any of the two networks? If you mean network adapters, you should only have 1 or 2 depending on the ethernet ports on the back of your computer.

If that is the case, then you go the Network and Sharing Center and click on Change Adapter Settings on the left. Right click on the unused adapter and disable it, althouth it should be disabled by default. If that's not what you meant, please elaborate.

When you click the network icon near the clock, it shows "Currently Connected to:"
and there are two networks, one is named Unidentified. And when you got to the "Open Network and Sharing Settings" try to look at "View your active networks" and again you will have two networks. Click "Local Area Connection", the one that belongs to the unidentified network and when the status window shows, click Disable.

After that both networks will be disconnected. Click the network icon and select "troubleshoot". When it fixes the problem the unidentified network will be gone.

This worked for me.. hope it does for you too.

Yes that's what I was doing. I had to disable and re enable on every start up. I fixed the problem by creating static IPs for each computer. Once I assigned an IP to each computer, the unidentifed network never popped up again!

Try to run cmd.exe with administrative rights and input:

ROUTE DELETE 0.0.0.0

This should solve it.

I have found some older networking hardware acts flacky. I had a D-link network adapter that didn't work and after reading about it on-line found it had been very spiradic with Windows 7, bought a new adapter and everythign works fine.

It appears there are a ton of solutions to this problem so, I will add mine in hopes that it works for someone. After fighting with this problem for an entire day I decided to go into my router settings where I increased the ip range from .4 to .8. I also removed IPV6 from both my LAN and wireless connections (not sure if that helped). That fixed my issue.

For those who might want to know why I did that let me explain. I tried doing an ipconfig /renew but it returned an error message indicating I had conflicting ip addresses. That when I decided to check the router's control panel and sure enough the first 4 ip's were in use.
, hence the increased range.

Hope this helps someone

I tired everything and nothing seem to work, except this. click on start, accessories, right click on command prompt, run as admin. then when the command prompt pops up type in netsh winsock reset catalog and hit enter. Then you will have to restart your computer. when windows reboots you should be all set. let me know how it goes by emailing me at adamnorrad@gmail.com

SUNSPOT2's suggestion works! I had exactly the same problem with the unidentified network that windows 7 cannot fix. I search for cmd.exe and right click, then run as administrator.... then type ROUTE DELETE 0.0.0.0... then it responded OK!. The phantom network is gone! Thanks...

I had same problem with unidentified network. I upgraded Vista to Windows 7 Ultimate and could not get my network identified or get online. I tried everything and nothing worked. My motherboard is a Gigabyte and I looked for new drivers on their website. I went to gigabytes website and downloaded latest drivers for windows 7 onto a flash drive. Inserted flash drive into my desktop and ran updates. this instantly gave me internet access! Hope this helps!
