Windows 10: Ethernet connected but unavailable for use, Windows auto assigning me a 169.254.xxx. IPv4

I’ve tried many possible solutions and even reinstalled Windows at this point. Doing command prompts does absolutely nothing and neither does restarting my network adapter. I’ve checked settings for IPv4 under my Ethernet properties and they’re all set correctly. This is seriously frustrating, any help is appreciated

Only IPV6 connection through ethernet, ipv4 not connecting (Through google fiber, no router/modem)

1. I was last able to access sites two days ago at night. Yesterday, all ipv4 connections failed.

2. I last patched to the latest version of windows 4-5 days ago, but internet was working fine for 2-3 days after the patch.

3. I'm using chrome, I've tried Edge to no avail.

4.

• I plugged a different computer into the same cord and ethernet port, got the same problem
• I plugged the this computer with the same cord into a different ethernet port, same problem
• I plugged this computer with a different cord into the same ethernet port, same problem

I believe it may be an issue with the building's ethernet itself. However, using a wireless connection to a router that is plugged into the building ethernet through a third port works fine.

I also tried all the steps linked there, no success. I have also tried forcing static ip's for IPV4 connection, but no success there either.

 

Windows 10 LAN or WiFi networking gets 169.xxx address on DHCP or static

Surface Pro 4. Windows 10 1709 16299.251

Looking at the above device for a friend. When connecting to network on WiFi it asks for key instantly, and when type in, attempts to connect and then comes back with a "No internet - secured" message. An IPCONFIG shows it has a 169.xxx address. If I config the IPv4 manually with correct details there is still no internet and I can't ping the device. Multiple other devices working on network.

Plugging in a ethernet dongle the same behaviour is exhibited on LAN so believe it's a Windows issue or some sort as discounted adaptor.

• I have tried removing all adaptors/protocols and reinstalled / rebooted
  
• Reset winsock via cmd
  
• Reset tcpip via cmd
  
• Disabled firewall
  
• Disabled AV
  
• Ran malware scanner
  

Any ideas?

Edit So I download the Windows 10 iso and performed a repair install. This resolved the issue.

Edit 2 Adding in case anyone has similar issues. Windows then updates and breaks the networking again. It's either KB4088776 or KB4058043 that kills it. Annoying that this is on a Surface! - not sure how to proceed now

 

Windows 10 - Ethernet has a invalid IP-Configuration

Another thing to try that worked for me if none of the above does... In addition to resetting my router I had to reset both WIRE LINE adapters.

This solution may be helpful if your IPv4 address is automatically assigned to 169.254.*.*, which means your Ethernet hardware can't connect to the router to be auto assigned a IPv4 address.
