Unidentified Network - "Ethernet" doesn't have a valid IP configuration

[kevalalajnen]

A few days ago my wired connection just shut down. I've been running on my wireless connection for a while now but I think it's time to get this fixed.

Before I start explaining more in depth, _yes_ I have tried another cable, _yes_ I have restarted the router, and _yes_ I have disabled my WiFi through all this.

Okay, so, when I right click the Ethernet adapter in Network Connections and Diagnose it, the problem Windows finds is ""Ethernet" doesn't have a valid IP configuration."

I have tried ipconfig /release and ipconfig /renew - after which I get the following message: "An error occurred while renewing interface Ethernet : unable to contact your DHCP server. Request has timed out."

I've also tried "netsh winsock reset", which didn't do anything.

I've tried assigning a static IP to the connection. It wouldn't work, but I'm not sure I did this right. What should I put as preferred/alternate DNS server?

I've now reinstalled Windows as a last resort, which unfortunately didn't help, however we can now rule out other software is messing with the connection.

I don't think there's an issue with the actual network card, all the lights are working, Device Manager shows it as working, and it does recognize the cable being connected to a network.

There's probably some stuff I forgot I tried, feels like I've been in every menu in my PC and router by now, but start shooting ideas at me and we'll see what we can do.

Here's my ipconfig /all:

Do other devices connect just fine?

 

[kevalalajnen]

Yeah, both wired and wireless devices work.

 

[Barty1884]

Are you wired directly to the router? Or through a switch &/or over powerline?

 

[kevalalajnen]

Right now through a switch, but I've tried connecting it directly as well.

 

[Barty1884]

And no change? Good to know.

What are your system specs?

I assume after your clean OS install you reinstalled your network driver from the motherboard vendor website?

 

[kevalalajnen]

Yes, I've tried updating the driver. No change.

I'm running Windows 10.

Mobo: ASUS ROG STRIX X99

GPU: GTX Titan XP + GTX 980

CPU: i7 6800k

RAM: 4x8GB 2400MHz DDR4

PSU: 850W gold certified

Is there anything else that would be relevant?

Okay, so I tried connecting another new device (my Wii U) and it didn't work either. I gathered from other posts that it might be something with my routers DHCP settings. Now, since I factory reset my router it seems I'm unable to log in to it with any default info I've found, or the info I've got from my ISP... So I ordered a new router free of charge from my ISP. I'll just keep running on WiFi for now and we'll see in a couple of days if this solves the problem. If not, I'll be back to bug you over the weekend
