Problem with Ethernet connection Port not functioning properly
Problem with Ethernet connection Port not functioning properly
I connect an Ethernet cable to my PC but don’t see any notification about it being linked. The internet connection appears disabled for the port. Moving another PC works perfectly. Checking the motherboard site, I download the latest LAN driver for Windows 10, but installation fails with compatibility warnings. Updating the Ethernet port via Device Manager shows it’s already up to date. Should I assume the port is faulty and avoid wired internet until a different motherboard is used?
Is this a brand-new motherboard or does it no longer come with a warranty? If it's covered under warranty, the manufacturer might be willing to replace it. Otherwise, for just gigabit Ethernet, an adapter card is very affordable and easy to find. You could purchase one and install it in any spare PCIe slot. It could also serve as a reason to move up to 2.5 GbE if you plan to expand your network later.
it's old and out of warranty. It's SFF, a Louqe ghost s1; so i doubt there's space for a card
Fairly, most ITX boards feature just one PCIe port for the GPU. A USB adapter could work if you have extra ports available. There are also 2.5 GbE connections that aren't too expensive: https://www.amazon.com/dp/B0BNHK5RGL/ I actually prefer having a USB-C Ethernet adapter on hand in case I need it for my phone. It's not a widespread requirement, to be honest, but it's useful to keep it nearby. (In a way, it’s connected to the laptop about 99.9% of the time.) Simple 1 Gbit connections are available for under $10: https://www.amazon.com/dp/B09GRL3VCN
It's not related to the driver. The basic Windows drivers work with 99% of available LAN chipset models. Turn off the PC and inspect the Lan port pins for oxidation. If found, disconnect the power cable and remove the CMOS battery (CR2032). Use a small flathead screwdriver to carefully clean the oxidation from the pin tops. Be sure to remove the PSU power and CMOS battery beforehand and avoid using any cleaning agents. Gently wiggle the cable to check for even detection; if it works briefly, the cable may be damaged or contacts are corroded. You might need to crimp a new connector or replace a damaged patch cable with a fresh one.
