Unidentified Network - No Network Access, since downloading Windows 7

I'm following this post since it also pertains to me.

My setup:

Asus M2N32 Sli Wireless Edition Mobo with nForce Network Controller. Real-tek Wireless Built-in.
Router: Linksys WRT110 (Factory Firmware)
I also use a switch in my setup: Linksys 5 Port 10/100 EZXS55W

I have a laptop that connects wire-lessly with no issues. My Desktop with the Asus Motherboard has built in Wireless which connects fine.

When I try to use the wired network with the desktop, Windows 7 shoots out the "Unidentified Network". Weird thing is, it worked fine for the first few hours of operation as a wired PC. Then the PC went to sleep and I haven't been able to revive the wired network since.

Running wireless wouldn't bother me, but I use this PC as a Media Server and Voip Server. Wireless doesn't always cut it in these circumstances.

I've tried uninstalling and re-installing the network drivers. I've tried setting the adapters to a static IP.

Here is a list of the different fixes I've tried:
Windows 7 Unidentified Network, Limited Access, No Internet Connection Problem Resolved

Change ‘Unidentified network’ from Public to Work in Windows 7 - dimeby8 - Site Home - MSDN Blogs

Windows 7 Unidentified Network Help!

And about a dozen more...my history is already gone though.

I don't know what to do, it was working fine in Vista for 9 months. Win7 was working fine for half a day. Now, nothing. I'm open to ideas...I'll mess with troubleshooting. I think I've narrowed it down to the router, or the switch. I've read that Windows 7 has the ability to "detect" my switch and gets confused where the default gateway is even though it's programmed statically.

I'm at my wits end with this, why does everything else work fine...and my HARD WIRED network doesn't. Very frustrating.

Other people with your exact model of board seem to have the same problems with the wired connection and Windows 7. The Asus site shows some possible fixes that might work for you.

You might also want to update your network drivers directly from the Nvidia site.

chev, do you have any questions or anything that could help you solve my problem? I could give you info, if you want more IP info let me know how to obtain and I'll tell you.

Make sure your router firmware is up-to-date. We upgrade all the drivers in our PC for Windows 7 but forget to upgrade the router firmware. I upgraded my router firmware and all those unidentified network problems went away. It is much easier than forcing windows 7 to work with an out-dated router firmware. I wish this forgotten upgrade of the router is promulgated by Microsoft. Consequently many of us wasted a lot of time on this one.

I recently got bit by the limited access network, no Internet connection problem and here's the solution I found.

I am running Vista Home Premium. Recently I tried to install Microsoft Security Essentials. The install failed.

As I researched this, I found that I had not gotten any Windows updates in several months.

So I decided to go back to the last recover point, which was around the time I stopped getting OS updates.

After going back to the recovery point and rebooting, I lost Internet connectivity.

Running ipconfig showed an ip address that started with 169, so I knew that my router didn't give me an IP address as it should with DHCP turned on. Also, there was no gateway.

I searched the Internet for solutions and tried all sorts of things (the regedit solution, a new, different second NIC card, tested the CAT 5 network cable with another computer, turned some services off, turned other services on, static IP address), but nothing seemed to work.

Then when I looked at my network stack, I saw the standard Client for Microsoft Networks and the TCP/IP protocols, but I also saw an entry from Symantec.

My computer from HP came bundled with a trial subscription to Norton Anti-Virus. The subscription had expired some time ago and before installing MS Security Essentials, I uninstalled Norton using standard Vista software removal procedures.

Well it seems that the standard procedure doesn't always work right. I found a reference at a Windows Q&A site to a Norton utility that would remove all traces of Norton products in the event that a partial install was creating problems.

I downloaded the tool from Symantec Norton's site, and presto my problem disappeared completely. Within twenty minutes, I had the almost 50 OS updates I missed downloaded and installed, along with MS Security Essentials.

So watch out friends. A partial or otherwise corrupted Norton Anti-Virus install could be your problem too!

I know this is a really late response to this problem and I really wish I could have posted it when you presented it. However the way that I fix this little error is I have to unplug my computer from power completely. Meaning unplug the power cable from the back of the PC tower, out of the PSU. Wait aprox 10 seconds to be sure all the power is drained (lights should go off on MB) and then plug it back in and viola! it works. Standby does something strange to the network probably due to the AI NAP feature that asus implemented. The network is designed to always stay online for networking reasons and standby powers everything off in a way that it doesn't like. So I'd suggest if anyone ever has a problem like this on a laptop to disconnect the thing from the charger and unplug your battery for about 10 seconds and then hook it all back up. I would imagine it would operate the same way as my desktop computer does. How to fix this? I don't know yet but I'm going to look into it because I would like to be able to use a standby feature as it's the best way to save wear and tear on your harddisk headers. Also saves A LOT of boot up time lol. Peace
