Intermittenly, I can't get wireless for some reason and get the msg: "Wireless doesn't have a valid IP configuration", with "unidentified network, no network access". In the past, I could just plug in to the wired connection and theIn suddenly, it would recognize the wireless. I can't seem to get it to work after reboot, turning off the router, etc. I've looked through other posts and tried various things and I don't have bonjour anywhere either that i can tell.
Any ideas? This makes me crazy! Thanks!

If i run ipconfig, i get:

Solution
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 Windows 7
reinstalling XP (I had a dual boot and I did both, losing all installations)
manually...

Try this:

The Fix
  1. Start by running cmd from the start menu
  2. Type “ipconfig /all” without the quotes
  3. Write down the physical address of which ever connection is/are not working. If you are hard wired to your router, then use the Ethernet adapter physical address. If you are running wireless, then use the Wireless LAN adapter. I had to do this for both.
  4. Go to your router's firewall and find the physical addresses of the connections.
  5. Find the physical address(s) of your blocked adapter(s) and unblock it.
Sorry I can't be more specific for everyone's router but that is the general idea. I'm using Win 7 but I don't think it makes any difference.

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

Fixed it ... after thinking about it and trying a few suggestions .

Start > Control Panel ( Large Icons ) > Windows Firewall > Allow a program or feature > Allow another program > Right click on Bonjour Sevices and delete .
Close and reboot .

Hope this helps those with this issue .

** Hello, bassfisher6522 ** Thanks SO much for posting this. All this time, I was thinking it was my cable modem or Linksys router. I never really approached it as a Windows 7 issue. Thanks for pointing me (and others, I'm sure) in the right direction.
Thanks - Elizabeth (RebootITNow)
