A single glance suggests the Ethernet port might be faulty.
Hello, this path might be reaching its conclusion. This comes from a discussion above. The problem was download speeds remaining at 9mb per second. All changes except driver reinstallation were made; the suggestion here was to run Ubuntu and verify if speeds stay at that level, confirming the port is indeed inactive. Based on what you see, is that your interpretation? Thankfully, it's still covered under warranty. Ubuntu network:
In the discussion I shared, we made significant adjustments and swapped a few cables. We’re still facing an issue with 9mb of slowdown for my friend. Got any other suggestions?
Ensure every part of the setup is flawless for achieving 100mbps or 1gbps speeds. Your motherboard’s Ethernet connector needs to work perfectly. The switch, modem, or router’s Ethernet port must also function properly. The connectors at the ends of the cable should maintain solid contact throughout its length—avoid stepping on it or breaking any wires. For 10mbps, only a few wires are needed (like wires 1-2 and 3-6), but for higher speeds you require a continuous connection between your motherboard’s port and the final connector. Make sure no breaks exist along the cable. To verify, test the port on your device by connecting a reliable one—if it delivers 1gbps, the port is functional. Repeat with another device to confirm consistency. Finally, inspect the physical port for any bent pins or misalignments; they should flex properly when plugged in.
Focused on the details. With Ubuntu at 10 Mb/s, the issue isn’t the OS or drivers. Using the same cable from the router/modem, I connected two different laptops—each reached 100 MB down from 9 MB. When swapping the cable back to the desktop Ethernet port, speeds dropped to 9 MB. This suggests the problem lies with the Ethernet port itself, not the connection. Examining the pins showed they were properly aligned and spaced, yet the port felt loose or damaged. I suspect an internal fault in the socket. The sudden shutdown after removing a USB drive hints at a possible surge affecting the port.
It seems the Ethernet module might be defective or the transformer connecting it to the port could be faulty. For a simple fix, consider swapping it with another card in your computer. Check available PCI or PCIe slots—any empty ones work. Ethernet cards are inexpensive, usually 1-3 dollars on eBay or in stores. Here are some options:
- PCI card: https://www.newegg.com/rosewill-rc-400-l...6833166017
- PCI-e card: https://www.newegg.com/rosewill-rc-411v3...6833166019
- TP-Link TG-3468: https://www.newegg.com/tp-link-tg-3468/p...6833704060
Surge can harm Ethernet ports, USB connections, and audio devices. It seems the issue might be with the port itself rather than the components.
Thanks a lot for your assistance. It looks like the Ethernet port isn't working well, which is good to know. I'm planning to install a PCI card—specifically a micro gigabyte, with just one PCI slot behind the GPU. The trip seems complete now. Appreciate your detailed feedback, Mariushm!
I see, a PCI card is the best choice for you. There’s a PCI-e slot, but it might be blocked by your video card. You can adjust the BIOS settings to turn off the built-in network chip if needed (optional). Consider looking for a narrower PCI card so it won’t interfere with the video card fans.

Great! I was thinking about the case bracket, didn’t realize they produced even smaller versions. When the card arrives, it’s just about uninstalling and installing the LAN drivers for it, fingers crossed @mariushm? Can the bracket be removed? It’s been a while since I used a basic NIC card. Yes, the other PCIe slot is blocked by the GPU. Thanks a lot!
