Network issue - Ethernet doesn't have a valid ip configuration

I got my computer a few days ago and almost every day since then, for a period of time I notice that the internet connection was really bad. At first, I thought to reset the modem should fix it and indeed it did. But then I found out that the problem doesn't seem to be in the internet provider but in the computer itself, everytime I get that yellow flag I have to trouble shoot and after a few seconds I get a solution for:

fixed: ethernet doesn't have a valid ip configuration

Does anyone know how to fix this permanently? I did some google searches, but I wanted to double check if doing things like setting the DNS to google is a safe thing to do.

Thanks!

If the NIC isn’t getting a valid IP that has nothing to do with DNS.

What are your full specs? Did you order with or without windows?

Are you connected via Ethernet directly to your router?

I've heard of this being a problem with Windows fast boot (along with other issues that seem to be fast boot related). I would suggest that you try disabling fast boot in Windows. What fast boot does is to hibernate the kernel (and many settings) when you shutdown, on a restart the kernel (and settings) are restored, the idea being to make the boot process faster. The trouble is that this hibernate/resume does seem to cause some niggly issues.

To turn fast boot off (and assuming Windows 10) right click on the 'start' icon and select Power Options from the menu. Then click the 'Additional power settings' text menu item (on the right). In the window that opens click the 'Choose what the power buttons do' and in the Window that opens ensure that the 'Fast boot' checkbox is unchecked. Then shutdown (not restart) and do a normal power on.

You should also make sure that the IPv4 settings are set to use DHCP. Right click on the 'start' icon and select Run, in the run box enter the command 'ncpa.cpl' (without the quotes) and click OK. In the network connections window that opens right click on your Ethernet adapter and select Properties from the drop-down menu. Click on the 'Internet Protocol Version 4' entry to highlight it (be careful to leave the checkbox checked) and then click the Properties button. Ensure that both entries there have the 'obtain address automatically' radio button selected.

My bet is that this is fast boot....

I'm using a wifi router, but my computer is the only one with this problem. I have tried a number of different things so far such as checking if IPV4 was properly set, turning off windows fast boot, reinstalling the network driver, using "netsh winsock reset", but none of them fixed it.

I can reproduce it almost everytime I reset the computer.

I'll try some other tutorials today, maybe ipconfig flush or disabling IPV6

It’s more than likely a driver issue. An ip config flush just clears the dns cache, doesn’t have any effect on ip assignment.

I would go to the manufacturers website, download the latest network driver, then delete the current driver including related software.

Then reboot, and install the manufacturers driver.

Also, what version of windows 10 are you on? This was a common issue in earlier builds.
