"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

  1. 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.
  3. 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?

    I can go on one of my other computers and check, but this started once is changed the DNS server, Idk why it would be the ip
  5. 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! :)
  7. 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
  8. 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.
  9. 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.

    I'm having the exact same problem with my computer, even the fact that my phone and other computers on the same wifi seem slow... but fine. I believe it has something to do with my wifi card, since I can connect via ethernet with no problems at all. I have not yet tried to connect to another wifi (such as at a friend's house). I have, however, successfully connected to my phone's hotspot wifi with no problems, and am currently using my phone's 4G LTE through usb tether. So.... it is a bit confusing as to what EXACTLY the problem is (since I can connect perfecgtly through my phone's wifi, but cannot with my home router's wifi, but that everyone else in the house, including my phone when connected to the router's wifi all work just fine). It leads me to believe it is something to do with how my wifi card is communicating with my Comcast modem/router combo box. I have not called Comcast yet. I hope someone figures this out soon. I plan to call Comcast at some point soon.
  11. What you really need to do is:

    Go into your Control Panel

    Click Device Manager

    Click arrow to left of Network Adapter

    Right click on your network adapter, and select uninstall

    your network adapter will no longer be listed

    Go to Action on the top left of screen, just right of File

    Click scan for hardware changes and your network adapter will be reinstalled.

    Reboot Router, then reboot PC

    You will have to select your connection and retype in your password.

    Hooray! It took me a couple of hours to figure this out, no other methods listed on this blog worked for me. If for some reason it doesn't work right away, reboot again. I had to.

  13. Much as I like cmd configuration tips, the simple answer often IS the best, and removing Bonjour worked thatfast for me.

    Thank you lisapigg! This was simple and worked perfectly. Much appreciated!!
  15. Plss i don't have this bounjur what will I do
  16. Open up a command prompt as an administrator. type in: NETSH WINSOCK RESET
    Restart your computer. Only thing that worked for me.....
  17. Does it work on windows 8
  18. I am having the same issue. I have four bars of service but no network access. I removed bonjour, did the command prompt thing, disabled/enabled, all to no avail. It started at work when my computer crashed and I had to restore but I'm having the exact same issue at home that I was having at work. I can't connect with a cable either. I then get "Ethernet has no ip configuration". Any ideas? I'm on windows 8.
  19. I have been researching multiple forums trying EVERYTHING, but NOTHING worked until...i added a default gateway. Network and Sharing Center > Change adapter settings (left side) > Right click on your network adapter then go to properties > Select IPv4 and go to properties > click advanced then go to "Add..." under default gateways then input your gateway address (mine was 192.168.1.254) and keep automatic metric checked then click add. Your network adapter should refresh and BOOM!


    This worked for me and your issue can be completely different but I just thought i would share this with you folks! Good luck everyone!!!

    AMAZING tip!! I was just stuck with limited connection on my laptop and couldn't figure out at all how to fix it. Tried this and worked like a charm. You're a lifesaver :-)
