Prime X570-P Gigabit Ethernet is no longer functional.
I'm running out of options. Everything seems to be working fine—no cable problems, network gear, or driver issues. The Realtek NIC is stuck at 100Mbit, and even when connected directly to the fiber modem, it doesn't reach gigabit speeds. I've tested various cables, drivers, and settings, but nothing changes. I'm really stuck and don't know what else to try.
You likely have a non-functional port or chip—use your warranty or return authorization if available. Otherwise, consider swapping the Ethernet chip, though it’s not very practical. A better option would be to install an Ethernet expansion card or modify the board.
Review the driver configurations, focusing on the green Ethernet connection and additional power-saving features, along with Duplex settings.
I'm starting down that path now. Sadly, ASUS doesn't have the advanced RMA number available, and I can't afford to be without my computer for an unknown amount of time since I've been working from home.
You can also obtain a quality USB C or USB 3.0 to gigabit Ethernet adapter at the moment and utilize it or a PCIe network card.
It's tough locating a reliable copy locally. I'm prepping for the first raid tomorrow and don't want to risk a glitch or crash. A 100Mbit connection should work, but I'm concerned about potential hardware issues that could cause unexpected failures.
It's perfectly okay with 100 MB for a game like Destiny. The chip could be damaged, the firmware might be corrupted, or there could be a driver issue that will be fixed later. Just make sure to keep in touch with ASUS about repairs or returns if needed. If you need help finding a replacement, let me know your location and budget, and I can suggest some options on Amazon.
