Vista: unidentified network

[chicagotech]

Try these:

1. turn off the IPv6.
2. Assign static IP.

Please post back with the result.

Hey guys,
I've just recently installed Vista Business onto my desktop. However, I
cannot connect to my router using Ethernet connection. The Network and
Sharing center will identify the network as "unidentified network", with
limited connectivity.

I've checked with motherboard and chipset company, and my motherboard does
support Vista. I've also updated my Ethernet network controller with the
latest driver. Aside from that, I've also disabled IPv6, and both of the Link
Layer Topography Discovery Managers. I've tried connecting the Ethernet cable
with my XP laptop, and it does work. Thus it seems to be my Vista machine's
problem.

If anyone has comments or recommendations, please feel free to contribute.
Thanks in advance.

I recently re-located my computer from underneath my desk to on top of it. Although it was working perfectly before, when I hooked all the cables back up again, much to my dismay, I was no longer able to connect to my home network. I tried all of the standard renew/release IP diagnostics, and ran the configuration tests, and nothing worked. I am baffled that simply unhooking my network cable, then re-connecting it could cause such a problem. I will walk through the steps I have taken to try and solve the problem, and welcome any feedback or solutions on the matter.

1. I disconnected the ethernet cable from my PC and connected it to my laptop (which I'm using now) to make sure that the cable wasn't my problem. I disabled the WiFi adaptor on the laptop, and was able to connect to the network and internet using the ethernet cable. (ruling out the cable as my problem)

2. I reconnected the ethernet cable to my PC, disabled my LAN adaptor, re-enabled it, and watched the status go from 'Identifying. . .' to 'Unidentified Network'. So, I ran the network diagnostic tool, and it gave me three options . 'Automatically get new IP settings' which did not solve the problem. 'Reset your router' which also did not work. And 'reset the LAN adaptor' which didn't work either.

3. Used my laptop to download the new driver for my LAN adaptor, burn it to disc, install it on my PC, then update my driver. Problem is still not solved.

4. Starting to get desparate, I disabled Windows Firewall, reset my LAN adaptor, and I was still receiving the 'Unidentified Network' message.

5. Re-enabled firewall, changed network settings to Private, from Public (which it was defaulting me to), turned off all file sharing and reset the LAN adaptor again. Still got the 'Unidentified Network' message.

6. I went into the Properties menu of my LAN adaptor, and looked at what it had for an IP address. . . To my surprize, it was getting 169.254.90.121, with a subnet mask of 255.255.0.0. I do not know if this is window's default IP address when it can't connect to anything, but what I should have seen, had it been working properly was 192.168.1.64, subnet mask 255.255.255.0. So now clearly, something is stopping my LAN adaptor from communicating with my router.

7. Call MS Tech support. . .They can't help me. Well, they can't help me for FREE. Turns out because I bought the OEM version of Vista I have to pay for tech support. Fortunately, the Techie from MS was nice enough to give me this piece of free advice. . . 'call your ISP'.

8. Called my ISP, repeated steps 1 - 6. Banged head on desk.

9. Visually inspected my router, and noticed that the port that my PC was connected to IS indeed lit up, showing that it knew something was there.

10. Used the laptop to access the router's configurator, and did not see my PC as an active connection.

11. Lost all hope.

This has been a really frustrating problem because everything WAS working properly until I unplugged all of the connections from the back of my computer, then re-connected them all 10 mins later. I have read through most of the posts on networking problems, and couldn't find any answers, so I'm starting a new post in hopes of finding one.

My vitals are:

O/S: Windows Vista Home Premium OEM 64-bit Edition

Processor: AMD Athlon 64 3200+

M/B: Gigabyte K8 Triton K8T890

LAN Adaptor: Marvell Yukon 88E8053 PCI-E Gigabit Ethernet Controller

LAN Adaptor Driver: 9.16.2.3

Modem/Router: 2wire 2700HG-E Gateway combo unit provided by Telus

Any help would be greatly appreciated. Thank you.

Hi reddevil,

I had the same problem and fixed it. I hoop it works for you as well. It is
not a very nice solution but hey, it works.

What I did was the following: I clicked the properties of the network
connection that was causing the problem. Then I selected the properties of
'Internet Protocol Version 4' and entered an IP address myself, subnet mask,
default gateway and the ip addresses of my ISP's DNS servers. That did the
trick. Save your changes and you're ready

good luck

Had similar problem after RC-1 install. Ran through all troubleshooting
procedures. Finally stumbled on following suggestion in Vista Help:

"Turn off the power-saving option in the network adapter's properties (wired
network adapters only)"

Checked out the adapter properties and power saving option was indeed turned
on. Cleared the check box, and my home network magically appeared.
(but it is still named "Unidentified Network" !)

[chicagotech]

Guess what... I got my Wireless Music working on RC1 build 5600 x86! Here's the scoop...

I did a IPCONFIG /ALL and noticed that the "Unidentified Network" is associated with "Nortel IPSECSHM Adapter". I have another issue with MS that is about a problem I'm having with the Nortel Contivity Client with the EACFilt component of the Nortel VPN client. This made my have a ahaa moment... I uninstalled the Nortel Contivity Client which removed EACFilt from being tied to my NIC. This got rid of the "Unidentified Network" and best of all... I now have my SB Wireless Music working again!

If you go to the Network and Sharing Center in Vista do you show more than one network?

[toymaker]

I have the same "unidentified network" problem as above post.

After I upgrade to Vista, my desktop can't get IP from my ISP's ADSL modem anymore. My connection always show " unidentified network" and I never get IP address.

However, if I reboot my desktop to XP again, I DO NOT get this problem and can get IP address and use PPPoE to connect successfully.

So, what I can say, IT IS VISTA ISSUE. I have already uncheck IPv6, QoS, Client for MS Networks, etc, and tried to config to try lower speed (10 & 100 Half/Full), I still get the same result "unidentified network" .....

Also, my Vista in my notebook has the same problem, but if I reboot to XP, it works perfet to get IP.

My NIC is very low end model "Intel(R) PRO/100", and I have tried different NIC too, still the same result.

My version of Vista is Business 32bit and is original DVD from Dell.

By assigning a static IP to the NIC is not an option, since it has to get IP from ISP in order to use PPPoE.

I would be great if any one can help.... It seems I get crazy about the "unidentified network" network issue in Vista.

[chicagotech]

Do you know the Microsoft has a update that may fix this problem? You should find the link by searching this forums

[chicagotech]

Using Vista Ultimate. Just this past Sunday had networking problem start.

On starting Vista, there is no internet connectivity. Network and Sharing
Center shows two networks--Home and Unidentified Network. The only fix that
works is to disable the Unidentified Network , then go to Device Manager and
disable my network card. Then in the graphic of my Home computer and the
internet, click on the red X and go ahead with the Diagnose and Repair dialog
that displays. It tells me that my LAN card is disabled, do I want to enable
it? Click Yes, and it repairs. I can access the internet again.

I reset the cable modem and changed cables, but that didn't solve this
problem.

Does anyoen have any advice?

As said this is the router/modem/NIC incompatible with the Vista. When the computer turn on IPv6 can't receive the default gateway which is 0.0.0.0 so that you can not access the Internet. However, after repairing, the default gateway is setup to Default Gateway . . . . . . . . . : 75.68.168.1. the solution could be as simple as disable the IPv6.

It is solved for my part. Bought a new nic and that was it.

Actually I "borrowed" a really old intel pro 100 from work.

So there you go, get yourself a nic if you have my problem. Looked
around in stores and they were as low as 10-15$

Vista Unidentified network Problem


It is a bug in Vista.
Vista does not preset a MAC address for the network card.
As a result the network card identifies itself as: 00-00-00-00-00-00
this causes problems with any standard equipment.
To fix this go to:
Device Manger and view driver details for the network card.
To set your MAC Address:
Once on the properties page for your network controller:
Click on the "Advanced" tab and then "Network address."
You will see that the option Not Preset is ON
To the right, fill in the "Value" with a unique address.
It should be 12 characters using hexadecimal digits example: 001a2b3c4d5e
Good luck!


Save and restart your network. It should be working now.

I had this problem too and searched the Internet for 5 hours and tried all the troubleshooting methods listed on this page and others to no avail. Then I finally I found a simple solution that WORKS like a charm.

SOLUTION: Go to http://support.microsoft.com/default.aspx/kb/928233 and make only the registry modification described under "MORE INFORMATION". (Note: I did NOT make the first registry edit listed on that page, i.e. steps 1 through 7.)

MY STORY: I am running Windows Vista Ultimate 64 bit OEM with all the latest patches that are current as of the time of this posting. My router is a Linksys WRTP54G-VR. The problem first materialized after I used the "Merge or delete network locations" feature to delete some unused network profiles. I then disconnected my Linksys router (only because I was needing to take it somewhere with me). Next, I had connected my cable modem directly into my PC. After re-booting my PC, Vista would not connect to the Internet, and "Local only" network access is all that would work.... Vista would not recognize my network profile by name, and instead would identify it as "Unidentified Network". The workaround solution I was using before I made the registry edit was simply to disable and then immediately re-enable my Local Area Network.

Good luck. A very simple solution to a problem that dogged me for a long time.

[chicagotech]

Thank you very much.

HispaTex, thanx very much, worked like a charm

In many cases, the Unidentified network is gateway issue. Make sure the default gateway i snot 0.0.0.0 or don't setup two gateways.
