"Ethernet" doesn't have a valid IP configuration

baileyboy125 · Mar 11, 2017

I know that this question has been asked many, many times, however nothing I have tried works. The computer is over 4 years old (custom built) and have not had many issues. This problem just started suddenly without warning. Wifi works completely fine, although this PC has really bad wireless connection so it is usually disabled (So there wont be any conflicting networks).

List of the things I have tried and their results:

*Used Command Prompt (Admin)
*netsh winsock reset

Sucessfully reset the Winsock Catalog.
You must restart the computer in order to complete the reset.

*netsh int ip reset

Resetting Interface, OK!
Resetting Unicast Address, OK!
Resetting Neighbor, OK!
Resetting Path, OK!
Resetting , failed.
Access is denied.

Resetting , OK!
Restart the computer to complete this action.

*netsh winsock reset catalog

Sucessfully reset the Winsock Catalog.
You must restart the computer in order to complete the reset.

*netsh int ipv4 reset reset.log

Resetting , failed.
Access is denied.

There's no user specified settings to be reset.

*netsh int ipv6 reset reset.log

Resetting Neighbor, OK!
Resetting Path, OK!
Resetting , failed.
Access is denied.

Resetting , OK!
Resetting , OK!
Restart the computer to complete this action.

*Uninstalling, reinstalling network adapter driver
*Updating drivers

Driver Version: 10.3.723.2015

*Changing LAN cable
*Turning off firewall
*Reseting and restarting router, as well as trying other ports
*Disabling and reenabling the network
*Made sure to tick 'Obtain an IP address automatically' and 'Obtain DNS server address automatically' (Though I have also tried to use manual addresses and DNS servers)

*Automatic diagnostic tool

What is internal ip address of your router?

First disable ipv6,
then run
ipconfig /release
ipconfig /renew

or you can set ip parameters manually.

If nothing helps, then it's possible your ethernet controller has died.
Get a new one - ethernet pcie card or usb dongle.

baileyboy125 · Mar 11, 2017

SkyNetRising :

Unfortunately this still did not work. The Ethernet is connected directly to the motherboard so I cannot replace this.
I have a seperate network card that is wifi only. The wifi works completely fine. All other computer operations work fine too.

SkyNetRising · Mar 11, 2017

Do you have a free PCIE or PCI slot on the motherboard?

baileyboy125 · Mar 11, 2017

My motherboard is an ASUS Sabertooth 990FX R2.0

Here is a picture of the motherboard and I have highlighted what slots are currently being used by the wireless network card and the GPU:

Goto your device manager under IPv4 and look if you have IP manually entered or not.

if dhcp, bottom section, change to manual entry and use 8.8.8.8 and 8.8.4.4 ase secondary, save and reboot computer do you get out now ?
if so the the gateway/dhcp is not properly set on your router

baileyboy125 · Mar 11, 2017

The Paladin :

I have already tried this. Thanks for the reply though.
All other computers in the house work completely fine.

SkyNetRising · Mar 11, 2017

BTW - you are using wrong PCIE slot for your graphics card.
Black PCIE slot (PCIe 2.0 x16_2) is limited to x4 operation.
You should use beige (PCIe 2.0 x16_1) slot for your graphics card.
Consult your motherboard user manual.

Use black, brown PCIE slots for your ethernet controllers.

baileyboy125 · Mar 13, 2017

I got myself a network card, but I still have the exact same issue...
Any suggestions?

Disable ipv6 and
repost output of ipconfig /all

baileyboy125 · Mar 13, 2017

This is using the port on the network card I installed today

baileyboy125 · Mar 13, 2017

Ummm... Something strange happened...
As I went to go disable IPV6 it just strangely started working again... after 4 days of hard work trying to get it working with no success, and it just starts to work on its own like nothing even happen...

SkyNetRising · Mar 13, 2017

Yes - sometimes ipv6 messes up things. That's why I disable it usually.

baileyboy125 · Mar 13, 2017

I see, thanks for your answer. However I had already tried disabling ipv6 and it didn't work... strange.

baileyboy125 · Mar 17, 2017

I was not ipv6.
Unfortunately the problem has started up again and nothing is working to fix it...

Perform

ipconfig /release
ipconfig /renew

Try different cable; different port on the router, reboot router.

Already tried a different cable, different port and restarting the router.

baileyboy125 :

Get rid of ipv6.

If that still doesn't fix things, you can also set ip parameters manually.

baileyboy125 · Mar 17, 2017

Unchecking ipv6 doesn't help at all

Also what do I need to type in when inputting the parameters manually?

SkyNetRising · Mar 17, 2017

Then set ip configuration manually.
And then try pinging your router.

baileyboy125 · Mar 17, 2017

But I am unsure as to what to type in

Is this correct: https://gyazo.com/64b786c2fe14f8d866732c06f375bc47 ?
