"Wi-Fi" doesn't have a valid IP configuration

Once upon a time, I accidently changed the DNS server address in "Internet Protocol Version 4 (TCP/IPv4)" and now my Wi-Fi is on an endless state of Limited. The title above is what the trouble shooter says.

It also says that during the trouble shoot it failed to investigate router or broadband modem issues, if that's important.

Other devices still connect to the wifi fine, and my pc connects to other wifi routers fine. It's just my laptop and this wifi.

Also, I think I changed the DNS to 8.8.8.0 or something. But I changed it back to "Obtain DNS server address automatically" but the problem still stands. I've done all those codes in command prompt (yes, in administrator mode) but none work. I think the fix lies with "Internet Protocol v4".

It's driving me nuts having to use an ethernet cord every time I wish to browse the internet, which is always. HELP.

Omg Microsoft," Result of diagnosis: There may be a problem
NOOOOO I DONT THINK SO.

Update: some pictures of my problem taken with my phone, since no internet

Check that it's also obtaining IP address automatically.

From going in command prompt and knowing that everything got jacked up after changing the DNS server, I can tell that that is the issue. If you click the link with my pictures, you can see that command prompt says that the DNS server is some weird symbols. I'm assuming that that is its way of saying that it has no idea, but I know next to nothing about DNS.

You're not being assigned an IP address. Nothing to do with DNS.

You're also on IPv6, which I'm a little less sure about. Those DNS server addresses are IPv6.

Do you know the IP address of your router?

Well, changing the DNS doesn't have anything to do with it - it can't talk to any until it's got a valid IP address. You could stick anything in there and it wouldn't know the difference until after it got an IP.

Hi guys, i had the same problem earlier on and it was soo frustrating!

Anyway i got it fixed (posting here using my revived laptop!) and the following was what worked for me:

Start > Control Panel > Windows Firewall > Allow a program or feature > remove Bonjour > reboot computer and watch the magic unfold.

P.S This was a solution posted by kind humans in another forum but it took me long to find it..Just thought i could share it on this forum as well to hopefully make the search easier for others.

cheers, hope this would solve your problem too! :)

so conect your ethernet cabo in your router and connect back to your laptop, go to control panel > device manager > network adapter > your network adapter > R clik and update it > desable it > enable it > take the cabo off and reconnect with you wifi and done! please shere with the world cuz if it happens again you know that the esyest is normally the right one

WOW .. it's true. I tried all the fancy IP address resets, then followed the advice by lisapigg and removed Bonjour and after the reboot, everything works.

So I too have tried everything I can find to fix this my trouble shooter switches between DNS not responding and ip config issue. Figured ie give this a go but I don't seem to have bonjour... Anyone else have an idea? Thanks guys.

Figured I should elaborate a bit more on what all I've tried.for starters this has been an off and on thing for about 2 weeks now,some days it works fine others its out for hours on end, atleast for my laptop my phone has no issue connecting. Some of the things I've looked up have worked for a day or a couple hours but without fail it crashes out. Obviously I have ran trouble shooter every place I can find it, I've messed with the adapter setting , changed them all to auto and I've tried to input the open DNS thing, which hasn't worked at all for me. I've disabled my local adapter. And even tried to reset my ip via ipconfig granted I think im on the wrong system for that to work. I've turned off fire walls and messed with my adapter properties. Needless to say I've tried to go about it as scientifically as I can changing one thing at a time and running trouble shooter reseting and trying the next. At times my connection says I'm online but when I try to load pages it fails and goes back to no access. When I open chrome it gives me the message (resolving host) in the bottom left, which is just it telling me it doesn't pick up a connection right? At times I've been able to force sites to load by
opening the page, starting trouble shooter and oddly enough pulling it up on my phone which seems odd to me but I think I'm just making it easier for my laptop to connect as there's already a link present... Granted I might just be getting lucky and they are unrelated I really have no idea.

I should perhaps point out that I use my apartments WiFi so I can't try and hard reset the modem/router as its locked up in an office. But given that my phone can connect to the WiFi that shouldn't be needed right?

Anyway sorry if there are any typos up there I'm awful typing on a phone, any other suggestions would be appretiated.
