Ethernet doesn't have a valid IP

[WaitDontSh00t]

I'm hoping someone can help me out here, I'm starting to lose my mind!

As of yesterday, I turned on my PC and everything was fine. I actually was downloading a game on Steam and left my computer for a minute. Upon coming back, I realized that my internet connection was gone. I'm not sure what happened, so I restarted and still...no internet access. Here I am, many many hours later still trying to resolve this issue. (**Note all other devices in the house are working fine).

PC Specs:

i7 6700k

Corsair Dominator Platinum 16GB 3000Mhz

Asus Maximus VIII Hero Alpha

Dual 980Ti Hybrids

Corsair RM1000i

 

When running the Windows Network Diag. it tells me that "Ethernet doesn't have a valid IP configuration."

I went into CMD and entered "ipconfig" and the default gateway is empty. It gives me an IPv4 address of 169.254.173.107

 

What I have tried (In normal and safe mode):

Restarting PC, Router and Modem.

ipconfig /flushdns

ipconfig /registerdns

ipconfig /release

ipconfig /renew (Said No operation can be performed on local area connection while it has its media disconnected & an error occured while renewing interface Ethernet: unable to contact your DHCP server. Request Time out.)

netsh winsock reset catalog

netsh int ipv4 reset

netsh int ipv6 reset

I've also tried uninstalling the Ethernet driver and reinstalling it

 

I'm not sure what else to try (I'm posting this on a laptop right now). I'm at a loss and desperate, I would GREATLY appreciate any help. Hopefully I provided enough info!

Thank you so much!

Does it help at all if you set a static IP on your adapter to the one of your network?

 

If it still barfs I'd try another NIC.

Setting a static IP didn't do anything unfortunately. 

I tried a different cable, but still the same issue. Unfortunately I feel like this is leading towards a System Reset!

How you tried resetting the router, just looking at the IP, 169.253.173.107 means your router isn't giving out IP addresses as it should.

Try something weird. Select your wifi and ethernet adapters and create a bridged connection. Then disable the bridge connection and also delete the bridge connection. For some reason, this works to reset the adapters in Windows 10 when other methods don't.

You can boot into a Linux livecd/USB to rule out software.

169.xxx.xxx.xxx addresses are provided when your machine is unable to obtain a DHCP address. I know you said you set a static address, but did you put all the details in correctly? If you set a static IP address using the following details: (change the following if your IP range is different...For example: If your router is on 192.168.0.1, change the IPs to match that format)

IP Address: 192.168.1.130

Subnet mask: 255.255.255.0

Default Gateway: 192.168.1.1

DNS: 192.168.1.1

 

Edit: Also try deleting your network device from Device Manager (including deleting the drivers if prompted) and reboot the machine.

Try downgrading network adapter drivers. 

check your router. Is it giving any errors?

I have a similar problem with one of my virtual machine hosted in my ESXI server.  It's not getting IP from my DHCP server and it cannot ping my router or any device on my LAN.

 

My virtual machine is running Windows 8.  My resolution is delete the network adapter from hardware device manager and then reboot the system.  The system rebooted, it automatically install network adapter drive and magically it starts getting IP from my DHCP server.

 

Sometime Windows is a weird beast and the fix is not logical.

I'm onboard with beersykins suggestion. Boot Linux off a thumb drive. If your internet returns and is stable then Windows probably did something while you were out of the room. If it doesn't show up or is very intermittent you probably have a dead onboard NIC.
