Local area connection doesn't have a valid IP configuration

Oskar Mason

So, I had a bit of a problem where the solution was that I had to port forward so I set a static IP. Anyway, the port forwarding didn't work out, but I stupidly kept the static IP, which was all well and good until I got a new router. 

 

I wasn't there when it was being installed but I do know that they removed the static IP (somehow).

 

I came home, and suddenly only my terrible WiFi worked and my Ethernet Cable was left in the dust, with the error message "Local area connection doesn't have a valid IP"

 

No idea why, tried unplugging and plugging back in and all that sort of stuff. 

 

Any suggestions?

Go into command line (windows key + R then type CMD into the run box) and run ipconfig
Find the settings your wireless card is using.
Copy the default gateway, subnet mask the first 3 sets of numbers to your wired network card for a static IP address and change the last set of number to something 10 numbers higher so you don't conflict with another device.
Forr DNS you're probably better of using google DNS. Primary: 8.8.8.8 | Secondary 4.4.4.4

Go to the "Network and Sharing Center" in the Control Panel.  Go to "Change Adapter Settings" then right click on the "Local Area Connection"  and then "Properties."

 

Click on the "Internet Protocol Version 4" and click "Properties."  

 

Make sure everything is set to "Obtain Automatically."   Press "Ok" and then "Close."  Plug in the Ethernet and verify the connection works.  If not,

 

Change the settings to this:

IPv4  Address: 192.168.0.31

Subnet Mask: 255.255.255.0

Default Gateway: 192.168.0.1

 

Leave all other settings the same.

If this does not work, Disable that adapter and re-enable it.

 

Best of luck,

Dautin

That does not need to be changed, your router takes care of all of that.  Just leave it to "Automatic."

Screenshot of error would be extremely helpful.

I'm not completely sure on this one.  Maybe someone else on the forum will have more intellecton the DNS stuff.

Click the "Obtain an IP address automatically" thing...

Sorry to sound rude, but do you really think I haven't tried that?

He was actually saying the solution as to why the automatically detect DNS settings is greyed out. Put everything on default (Turn on Obtain an IP address automatically).  The DHCP server on the router (The one that gives the ip address lease) is probably not giving an address and it's  not the PC's fault. 

 

To try and get an IP,  on the same "CMD" window. do the following.

Procedure A: Renew the IP lease

1. ipconfig /release

2. ipconfig /renew

 

Check if your Local Area Network Connection is ok. If not, then reset the router and Procedure A a go again. You can also try disabling your WiFi temporarily then do Procedure A once more and see if that makes a difference.

You could use Google dns: 8.8.8.8 and 8.8.4.4 I guess...

 

Or just copy the DNS that your WiFi gets (ipconfig /all).

 

Your WiFi DNS is already in a screenshot here too:

86.63.0.11

86.63.0.130

 Is this a problem?

I thought Google's secondary was 8.8.4.4...

To everyone that posted a solution - Thanks.

I contacted my ISP and they did something odd to do with bridging one of the ethernet ports on the back of my router.

Although, I'm know pretty much nothing about this, what is DNS?

Set you settings so they look like this

post-66930-0-06721400-1430559560.png

This will make the computer use DHCP and have the DHCP server (in your case your router) dynamically set the IP address for your PC and will use Automatically set the DNS to the gateway itself, which will forward it on to the DNS set in your router

 

Automatically setting the DNS will be an option when using DHCP

DNS - 

The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. Most prominently, it translates domain names, which can be easily memorized by humans, to the numerical IP addresses needed for the purpose of computer services and devices worldwide. The Domain Name System is an essential component of the functionality of most Internet services because it is the Internet's primary directory service. - Wikipedia

 

It basically acts as a file system for a network.  It tells services where to go and what things are.

 

Somebody correct me if I'm wrong :)
