wifi does not have a valid ip configuration windows 8

have you tried the instruction posted by Sam.is.a.common.name posted Nov 12, 2012

That worked for me..... Here's a copy

Press windows logo key + X and click on command prompt(admin) then enter the commands.  After a number of tries, it finally worked for me

Good Luck

I was having this problem too. Solved it by following the directions here:

This part in the first reply fixed the problem:

"With upgrades sometimes winsock or the TCP/IP stack gets corrupted. To reset them both type the following two commands into an elevated command prompt one at a timehitting enter after each one then reboot the system.

netsh winsock reset catalog (reset winsock entries)

netsh int ip reset reset.log hit (reset TCP/IP stack)"

Hope this helps someone else.

Cheers.

Thanks for really breaking it down for me.  I am not tech savvy so i appreciate your clear instructions from the start....... then i could follow Sam.is.a.common.name's instruction.   Thank you

WOW!  AFTER DOZENS OF SEARCHES AND TRYING DIFFERENT SUGGESTION......finally a fix. Thank you very much.

I wish you had told me how to get to the elevated command prompt (Windows + X) since I am not very tech savvy.    Thank you.  Thank you

FRUSTRATED to no end!!  The command prompt commands did not work, but what I have found on my HP ENVY with Windows 8 is that I can now logon at home; however, not at any other single location.  So obviously whatever I did ONE time worked for my home, but isn't working for anything else.    Obviously, when my phone and everyone else's laptops are able to login, the problem is NOT the router or any of the other useless suggestions.

I do not have the AVG antivirus or any other at the time I was having the problem.  After getting a temporary fix to be able to login at home, I then downloaded my ATT MCafee suite.   But the problem existed before then.   Even at home I have had to REFRESH my computer, so the fix was NOT permanent.

Today, after doing what was suggested on another thread, I have obtained an IP4 address, but no IP6, yet still unable to connect to internet:

Press windows logo key + X and click on command prompt(admin)

 now type in : ipconfig /flushdns

 then disable your wireless adapter ( network and sharing center -> change adapter settings )

 Restart your computer

 enable internet connection

So I am still desperately looking for an answer, now bc I have an IP4 address the troubleshooter says everything is working great.. Even though I can't connect to the internet... OMG!!  sooo frustrated.
