This new PC setup has an invalid IP address setup
Original post updated about PC Part List changes. A driver update resolved my network issue on Reddit, but I wanted to check for additional fixes. Assisted a friend in assembling a PC using both old and new components. We finished three days ago and installed Windows, only to face internet connection problems afterward. The error message stated "Ethernet doesn't have a valid IP configuration." We searched for solutions but none worked—tried command prompt tweaks, driver reinstalls, network resets, etc. We also attempted connecting to another network, but it didn’t help. After reinstalling Windows again, the problem persisted. Manually connecting to the network didn’t resolve it either. The error then changed to “the default gateway is not available.” Is this a motherboard issue?
Check if your device is connected through the router directly. If not, start there since problems might lie between the PC and router. It appears you can't obtain a DHCP address, and manually entering one doesn't show the router as a gateway on the network. When plugged in, switch to a different cable or port to connect. Configure the network adapter to use automatic IP and run: ipconfig /release ipconfig /renew
It might indicate an issue with the motherboard. Though this error often appears with Powerline adapters, it’s worth confirming the network cable connection.
The device is linked straight to the router. We tested two cables but none worked. Initially set to automatic failed, so we changed to manual. Recently returned to automatic, but the same issue persists—appearing as if it’s discoverable by other network devices (exact wording unclear). Running ipconfig /release provided partial data; ipconfig /renew reported an error: unable to contact your DHCP server, request timed out.
It was the motherboard I used before upgrading my computer and I had never experienced that problem before. We’re not using a powerline adapter; the machine is connected straight to the router. We’ve tested two Ethernet cables but haven’t succeeded. Could switching the motherboard resolve this issue?
Are you aware of your network's subnet (such as 192.168.1.x/24) when configuring it manually? If you're unsure or the router's IP isn't responding, the issue might be a faulty port or driver incompatibility. Consider downloading the driver directly from the manufacturer's site instead of your motherboard supplier. A UEFI/BIOS update could also help. Following @Windows7ge's advice about switching OSes might be useful. If nothing works, the problem likely lies with the motherboard. If it's under warranty, return it for repair; otherwise, you can buy a PCIe gigabit NIC for a low cost.
We are certain about the subnet. It could be a hardware problem. The motherboard is 2-3 years old, and I haven’t experienced any network issues during setup. This makes sense if something isn’t functioning properly after three years. Your comment about the driver from the network interface manufacturer’s site confused me; sorry for the confusion. Now that we talk about BIOS, it aligns with what you’re experiencing.
