I have brand new computer that I built myself, just got it all hooked up. The components are:

CPU: Ryzen 5 1600

Motherboard: AsRock B350 Pro4

RAM: G.Skill Tridentz 16Gb 2400

Storage: Samsung 850 Evo 500Gb SSD
Western Digital Caviar Blue 1Tb HDD

Video Card: Gigabyte Aorus RX 580 Xtr 8gb

I have it connected to my router (it's a modem and a router combination) through Ethernet, but it won't connect to the network. all it says is "Unidentified network" and "no internet access," and shows the Ethernet symbol with the yellow triangle over it. When I run the troubleshooter, it says "'Ethernet' doesn't have a valid IP configuration. When I run ipconfig in the command prompt, the IP address that is shown is a bunch of symbols rather than an IP address.

I tried to add a static IP address, but to no avail. After running the troubleshooter with the static IP address, it also says "missing default gateway."

Please do not make the effort to retype the results of ipconfig.

Cut and paste the "ipconfig /all" results into a file that you can transfer to another computer and then access Tom's Hardware. Or just pipe the output to a file somewhere.

No rush per se and you do have a few other options to explore and try in the meantime....

Do you have IPv6 service? If not, disable that on the motherboard's network adapter. Might be worthwhile to disable IPv6 even if you do have IPv6 service.
Just as a matter of elimination.

However, do go to the network adapter's manufacturer's website and download the drivers directly from the manufacturer. Reinstall from scratch.

Do not leave it up to Windows to find and install the correct network...

What make and model modem/router?

Do you have the User Guide/Manual?

Are you using the motherboard's built-in network adapter or some USB port or PCIx Ethernet adapter? Verify that only one network adapter is enabled and that that third party adapter (USB or PCIx) is fully connected in place.

Update the applicable drivers via the network adapter's manufacturer.

Run and post the results of "ipconfig /all" (without quotes) via the command prompt.

Overall, my thought is that some configuration error of omission or commission is the reason. Best to just double check everything and see if you can narrow down the possibilities.

The Modem/Router is an Arris NVG510. AT&T gave it to us when we set up our internet with them. I should include that all of the other computers in the house can connect to it just fine, using both wifi and Ethernet, so the problem doesn't seem to be with the modem/router. I might have a manual for it, but I have no idea where it would be.

I am using the motherboard's built in adapter. I didn't plan on connecting it to the internet in any other way than Ethernet, so I didn't bother to buy any other kind of adapters, neither for wireless nor wired.

I went into device manager and uninstalled, and reinstalled all of the drivers, and that had no noticeable effect on the problem.

I can't post the ipconfig info right now, as the computer itself can't access the internet at all, and I don't have time to type it all up right now, but I will try to do that tomorrow if I can. I can tell you that all the information seems pretty standard, other than the IPv4 address, which just shows up as a long list of various mixed symbols and numbers.

I really just finished building the thing, and this is one of the first times I even turned it on, the other time being when I installed Windows, and that time, I didn't have it plugged into Ethernet. I just expected for it to be ready to connect once I booted it up with it hooked up.
