Another: "local area connection doesn't have a valid ip configuration"

[Nebraindur]

I've read 3 hours worth of these on Tom's Hardware alone this morning, but the story basically goes like this:

I woke up today to a computer that was shut off. I seldom shut my computer down, so I'm thinking it was either a power issue or something requesting a restart and it never completed.

I booted up the computer, started under normal mode, and everything ran fine - except the network symbol in the bottom right corner of the screen. It has that wonderful little yellow triangle with a '!' in the center of it. It's labeled as "Unidentified Network."
After troubleshooting the modem and doing the ole power plug out/power plug in trick to the ubee modem/router model DDW3611, it gives me the message "local area connection doesn't have a valid ip configuration".
- Time Warned Cable automated services states there are no outages in this area at this time.
- My iPhone, which I am currently using to type this, is working fine when connected to the network (wirelessly).
- My PS3 connects to the PSN and online games via a wired network just fine.
- My device manager says my Network Adapter (Intel(R) Ethernet Connection I217-V) is working properly and the ASUS Maximus vi hero website shows I have the latest driver (checking via iPhone)
- My only recent activity was playing Arkham Origins, authorizing my cd key for windows 7 pro full, and therems always the possibility that Avast! Updated itself at some point.

Any help is greatly appreciated! I've got a very limited knowledge of this stuff and I am now out of ideas :-/

I had this problem a while ago and couldn't figure it out. I even ordered another Network card. By chance I turned off the whole PC including the power at the wall. Lo and behold, on boot-up, it worked! I can only assume that somehow the onboard network card somehow got 'stuck'. Last week, my daughter blew the power in the house and when I got home to my PC I had the same old Yellow triangle in the corner. I turned everything off (including the wall socket) rebooted the cable modem, waited for it to be ok, turned on the PC and everything seems fine again.

Give it a go.

You are genius! Can't even think that unplugging from wall would make this correct.. Thanks a lot.. :* :*

Just ran into this problem while reinstalling windows 7. Tried everything others had said until I decided to do the unplugging thing. I hit my PSU power switch, waited a few seconds, and powered it up and sure enough it worked. I'm very confused as to why this would happen during a fresh install... I've reinstalled windows multiple times during this last year and never once have seen this issue.

I've reinstalled windows multiple times during this last year and never once have seen this issue.

I've had this problem for the past 2 days. I haven't reinstalled windows or anything, nothing major has been changed, I turned it on one night and it wouldn't connect at all.
I've tried everything in this thread and nothing has worked. I'm still able to connect on wireless through my surface pro 3 and my iphone. My modem/router is upstairs from my desktop and using a TP-LINK AV500 Passthrough Powerline Adapter so I get direct Ethernet speed as if it was attached to the modem/router.

If anyone has any solutions...please help! Need internet to complete my thesis!

UPDATE! I fixed my problem! I took my desktop upstairs and connected it directly to the modem, and booted it up. It connected to the internet perfectly with a Local Are Connection, I then took it back downstairs and hooked it all back up including the Passthrough Powerline Adapter and it worked perfectly. I don't know how it fixed it...but it's worth giving it a go for anyone else having this problem.

Good Luck

I have a theory as to why this works, and it has to do with USB. I think, but don't know, that if you have AI Charger or something similar on your pc that allows you to recharge USB devices like a cell phone, even when the computer is powered off. This basically is allowing a 5v current, which is carried by all your usb hubs, plugs etc. And I think it extends to hubs. In my case, I had AI Charger disabled but still got the problem even after unplugging. Well, I had a powered USB hub plugged in and turned on, and I "Believe" but don't know for sure, that it sends that same 5v current down the USB super highway, and as it's self powered, unplugging the PC doesn't affect it. So I unplugged that as well, and on reboot... VOILA! it worked. Anyway, maybe I am way off but it seems that the aforementioned 5v current may also cruise around your PCI, ever notice how long the lights on your video card stay on? Even after unplugging? That current is enough to allow the nic cards onboard memory to hold onto it's previous info.

Just a theory, but seems plausible after my monkeying around.

What is wall means?

 

[T_Hansen]

Thanks for the reply dizzyh!

That solution doesn't seem to be working for me however :-/

Click Start.
Click All Programs. [All Programs - Screenshot]
Click Accessories.
Right-click on Command Prompt.
Click on Run as administrator. [Run as Administrator - Screenshot]
Type netsh winsock reset.
Press Enter. [Enter - Screenshot]
A message appears: Successfully reset the Winsock Catalog.
If Unable to reset the Winsock Catalog appears, refer the customer to Microsoft, or their OEM, for assistance.
Type exit.
Press Enter.
Reboot the computer.
Once the computer has rebooted, attempt to view a Web page.

THANK YOU - took me two hours of searching, but finally got to your text, and it solved it for me. 😀

netsh winsock reset.
Reboot the computer.

After trying all the other suggestions, this worked for me! Thank you!!

Try to see if you can access your router setup page by typing 192.168.0.1. I believe the username will be "user" and password "user". Click on gateway, then advanced gateway setup. You are checking the LAN setup not the WAN. Make sure DHCP is enabled and the range should be something like 192.168.0.10 to 192.168.0.100. Also anything pertaining to IPV 6 I would disable. Reading you post again, I see that you router is handing IPV 6 address and not IPV4.

It worked for me, thank you soo much

I had the same problem , but my dumbass had my antivirus in offline mode turned it back on and voila . If you're as dumb as I am this will be your solution . Lmao

 

[Goran Petric]

Well penetrate me in the ass! Unplugging it from power worked! I busted my balls trying to figure out whats wrong, i have caffe with 12 computrs on cable and some computers would randomly screw with me with no internet connection! Unplugging it violently from power and plugging it back after 5 minutes solved everything.... again .... penetrate me in the ass!

I have the same problem.. but what i do is that if you have a modem and a router, just unplug both, then go to device manager(run as administrator) then network adapters and uninstall the one that you are using; like mine is Realtek PCIe GBE Family Controller. then click "action" in the menu bar, next to "File" then wait after it install, after that you plug again your modem and router. hope it helps

 

[CMastereD]

I simply changed the ports rebooted the router and PC, however anyone reading this should check the condition of the ether net cable you are using and switch ports on both the routerms and PC, it should work but it is temporary and ithe failed 3 times on me so just repeat.

I just wanted to say thank you!

I had the same issue; powered up my computer ... lo and behold, the triangle of Doom appeared. I still had my wireless connection and could use my iPhone, which is where I found this site. I read through all of the possible solutions to see which had the most success in resolving the issue, and I found it:

Turned my computer off. Unplugged it from the wall and reset my modem/router.
As soon as I rebooted again everything worked as before!

So thank you! It was a quick fix.
