The Ethernet ports aren't functioning properly on my MSP430 B550 gaming plus.
The Ethernet ports aren't functioning properly on my MSP430 B550 gaming plus.
I recently purchased an MSI MGP-550 gaming plus from MSI paired with a Ryzen 3 3100 from AMD. When attempting to connect my Ethernet, it didn’t detect a connection at all. In Windows Options I checked, no Ethernet ports were recognized. After updating the drivers, I reached out to MSI, who suggested clearing CMOS and that fixed the issue. My assumption is the Realtek controller for the Ethernet port is faulty. Please help me, I’m almost giving up.
Activate the network card settings in BIOS. Verify the cable is correctly placed in the jack and that the internal pins are straight and not touching. Confirm the opposing device has the cable securely connected. Ensure the network card appears in Windows (Device Manager, Control Panel). The chip model is RTL8111H, it typically comes with built-in drivers—it’s a widely used network chip. If it doesn’t work, consider disabling it in BIOS and using a budget PCI-E X1 network card—this avoids returning the device to warranty and waiting weeks or getting a refurbished one back.
I double-checked the pins to ensure the cable was correctly placed in both my router and motherboard. I also looked in the settings and managed to locate the Ethernet card. I believe it might be faulty.
