Windows 7: Wireless Network Connection Doesn't Have Valid IP Confi

Yesterday, I installed Windows 7 Home Premium as an upgrade to Vista Home Premium. I followed instructions carefully and everything went well...or so I thought...until I tried to get online (via Linksys Wireless N Router which has always been able to communicate with a Linksy Wireless N Broadband Router in the same room). Until, now, that is. When trying to get online, I get the message, "Wireless Network Connection Doesn't Have Valid IP Configuration."

I'm not a techie, so trying to understand the postings for this problem was difficult for me, if not impossible.

Would it be best for me to contact Microsoft Support? Help! I have to use my wife's computer to get online and I'm running the risk of being thrown out of the house.Local Area Connection" Doesn't have a valid ip config

Hello Kodka, Welcome to the Windows 7 forum!

Goto Start->enter cmd, right click the cmd icon, and select to Run as administrator

Then enter in the CMD Window: ipconfig /all

Post the results of this command to this forum.
You can select the output with your mouse after you click in the left uppercorner of the CMD window (with the small icon of cmd) and select edit , Mark, then Copy, and then paste it in this forum with <ctrl><v> keys.

If you need more help just ask!

Best regards,

Good day.

I contacted Microsoft Technical Support and, a knowledgeable associate determined that my communication with the router should be WEP, not WPA as I had previously. Can connect without any difficulty now. Thanks for trying to help. I do appreciate it.

Happy days are here again.

Kodka;
I'm having the same problem

Thanks,

Ben

Uh, well the only problem with that is that WEP is old and easily crackable, it's better than NOTHING but only a little

I can't believe that Windows 7 doesn't support WPA? I'd try to get WPA working again myself, maybe google more for Windows 7 WPA setup instructions...

Well done Kodka!

Thanks for sharing your solution with us.

Have a nice day ;-)

How do you know whether our routher is using WEP and not WAP?

Hello guys, my laptop displays exactly de same message "Wireless Network Connection. doesn't have a valid IP configuration" . But I don't believe that the problem would be with the wireless because we've got others laptops working properly in our house. Plus, my laptop was working well 2 days ago and suddenly it has just stopped to get the internet working.

Could I post here the information from my laptop ,following the procedure posted here and perhaps one of you guys could , please, give me a hand?
