Ethernet doesn't have valid IP config. I am at an absolute loss

[cknox0731]

All online solutions I have tried do not work. All solutions here I have tried and do not work. Went to brothers with different ISP and router and it still did not work. I've replaced my motherboard (ASUS H170 Pro Gaming) with a brand new one and nothing. The only thing that HAS worked was totally wiping my computer and reinstalling windows 10. After 2 weeks, it stopped working again.

1) When I came home that day, computer was off which means there was either power outage or update and my comp turned off as it is usually sleep mode.

I have a laptop running windows 10 and the ethernet cable connections works fine with it. Also works with xbox.

I called a computer shop and told them everything I've done and they told me (honestly) that I'd waste my money going there as I've tried everything they would have.

I'm pretty tech savvy but hoping I'm missing something dumb.

UPDATE***** 4/5/2018

In frustration, I went to reset my whole PC last night as nothing was working (this has been the only thing to previously work in the past.) My plan was to then repost my ipconfig /all and compare. I could not reset my windows 10. I was receiving an error message "There was a problem resetting your PC."

- I tried the solution I found and putting this into CMD
cd %windir%\system32\config
ren system system.001
ren software software.001
- I got an error message stating that this process is being used or something and cannot be completed.

I then inserted the windows 10 flash drive to reinstall windows. After about 10 minutes, I encountered an error with the launcher and it could not download.......................

You have link lights on the motherboard? You tried different cables correct? What happens if you set a static IP? Remember to cofigure the Subnet mask and gateway when you do that.

- What are "link lights?" Is that just the lighting on the motherboard that indicate different issues?
- I have tried different cables. Also different router and ISP.
- I don't think I've tried setting static IP. I'm not sure how to do that, but I'm sure a simple google search will tell me how. I will try this later when I get home from work.

I will update after I have tried. Thank you.

Are you using a 3rd party anti-virus/firewall application? If so, temporarily disable it. Any possible changes to your hosts file? If so, reset it: http://www.thewindowsclub.com/how-to-set-the-windows-7-hosts-file-back-to-default
Did you check BIOS to make sure LAN isn't set to disabled? Or possibly any other LAN related setting in BIOS that may need to be changed?

I should not have said on the motherboard for the link lights, they are on the network jack, which is on the motherboard. Should be two small lights on either side that go on when there is a connection. Their pattern and color has some meaning.

Give the network adapter a static IP address and see if that fixes the problem. That way, you take hardware out of the equation.

The network adapter is failing to acquire an IP address and is using an automatic private IP; that's the problem.

- Disabled Webroot and nothing.
- Only option I found on BIOS was "Power Up on PCI card" It was disabled. When I enabled it, it prevented the "!" from appearing on my internet icon, so it looked like it was working, but still no connection.

- I have given it a static IP and it did not work. The steps I took to do so was ipconfig /all. I took the information from there and input it into my ethernet properties rather than the automatic option. I saved it. No internet

Did you give it a 169.254 IP address? If so, that isn't going to work. You need to use an IP address that's valid for your network (probably 192.168.x.x) along with the correct subnet mask and gateway. You can get this from the Windows 10 laptop.

For the purposes of testing, you should also manually enter a DNS server. Use your router's IP address for this.

I believe I have done this using the laptop to get the information as well as entering router's IP for DNS. I will try this again thought in case I have not. This has literally been a 5 month issue that I've worked on on/off so I forget everything I've done.

Wont be home until Sunday, so it will be a few days before I respond. Thank you for the help/suggestions.

Did you recently do the 1709 update?

One way to isolate windows and HW problems is to boot up a linux distro, like Ubuntu 17.10.1, put it on a usb stick then boot it in "live" mode and you will have a working desktop OS running. It should DHCP by default, it's a quick hardware sanity check.

Had similar problems with windows 7 after an update getting a network connection then not getting any DNS or routing (although dhcp strangely worked) tried so many things, linux worked just fine so my final resolve was to just ditch 7 completely and install 10 from scratch (usb stick) - didn't make a whole lot of sense to reinstall win7 it's such a hassle these days.

I will try to linux distro in a few days when I return home.

However, if that is the case, please see my update on my main post above. I cannot reset my PC nor reinstall windows 10. I want to believe that windows 10 is the issue, but I have my laptop running the same OS and it hooks up to the ethernet just fine.

Is it possible to be a OS and Motherboard communication issue or something? Is something like that possible?

ah I missed that bit about the win10 usb, also had that problem probably best to use the creation tool to download the ISO file then burn the USB using Rufus, good article on that here - best part about Rufus is you can choose "legacy" MBR/NTFS or GPT/FAT32 for UEFI BIOS, the creation tool seems to have a problem with that.

As far as the OS / Motherboard goes Linux would test that for sure - my bet is it will all be working under linux and you can rest assured your hardware is just fine.

Thank you for the help. I will test this Sunday/Monday when I get back. I will update after.
