Windows 7 Network Adaptor - No Valid IP Configuration

[ljcap]

Hi,

I have been using Windows 7 beta (386) with no problems up until a few days ago.

I've run into the The Network Adaptor "Local Area Connection" does not have a valid IP Configuration message. When I go to Network Sharing I see that I am connected to an Unidentified Network but unable to connect to the internet. This has happened all of a sudden.

The computer is an Acer Aspire M1610 and the router is a Dynalink RTA1046VW.

I've tried rebooting the router, changing ethernet cables, uninstalling the network adaptor and reinstalling all with no luck. Going into Device Manager says that all is ok.

No problems with any other computer running Windows 7 in the network. I suspect that my ethernet controller has packed it in.

Any assistance is greatly appreciated.

Cheers
Laurie

Hi guys!

I have had the same problem for a few days now, and have searched numerous forums and gone through hell and high water to fix it. nothing helped until I found the ultimate solution that will help everyone:

CALL YOUR ISP, TELL THEM WHAT HAPPENED AND THEY CAN CONFIGURE A NEW IP ADDRESS FOR YOUR CONNECTION. IT ONLY TAKES ABOUT HALF AN HOUR.

During this time you must keep your router/modem turned off, and after the ISP has fixed the problem (in my case it took half an hour) you must restart your machine with the router/modem on and connected. From then on it should be like nothing ever happened.

Just for the fun of it, here's a list of things I have tried without results:

release/renew ipconfig
restarting modem/router and computer about a zillion times
changing LAN card
creating a static IP
resetting winsock in command prompt
reinstalling Win7
reinstalling XP (I had a dual boot and I did both, losing all installations)
manually entering IP address
disabling/enabling local area connection
plugging and unplugging LAN cable
uninstalling and reinstalling LAN card driver
resetting modem/router using the reset button

And after all this, all it took was just a phone call.
This is because your ISP is THE ONLY authority when it comes to configuring your IP address. In this case, it can only be done from the outside. This is also the reason why Microsoft didn't announce any patches or fixes for this problem, because it is not their problem and responsibility.

Only one question remains, WHY is this happening? Noone has been able to answer this, and I have read tons of forum posts about it. Maybe even the guys that made Windows 7 don't know it.

I am going to copy this post on several other forums because I have seen the trouble that people are having with this problem.

If you find out why this is happening, please post it here.

? --so if i am unable to connect to the internet from my modem to my laptop this will fix the problem?

I have the same error message about "no valid IP configuration" my wireless can pick up my router but thats about it. I can not connect directly to my laptop. The only thing working is our X-box --just want to make sure we have the same issue before i call my ISP.

I have the same issue, I spoke to the internet company and they actually got it to show that i had internet but my computer wasn't accepting it. So the connection status didn't have the attention symbol but I still couldn't do anything with the internet. The isp tech cut me off when I told him this...

I did fix my issue, saved all my info and restore to factory settings and issue was resolved.
