I'm experiencing a frustrating issue with my internet speed on my PC. I have gigabit internet, yet my Ethernet connection is only giving me speeds around 2-7 Mbps, while other devices like my laptop or Wi-Fi devices are getting the usual 350 Mbps. Here are the specifics: I'm using Windows 10 on an MSI B550 motherboard, I've tried multiple Ethernet cables and ports, and even tested a different room's Ethernet port with similar slow speeds. My cable is brand new and capable of gigabit speeds, plus I have updated drivers. What could be causing this drastic slowdown?

If you're using an MSI motherboard, consider turning off the LAN manager optimization in their software. It's designed to manage traffic but can cause poor speeds if it’s set up incorrectly—essentially, it might throttle your connection when it thinks you're gaming.
A couple of things to check: 1) Has this slow speed just started recently or has it always been like this? 2) Do you have any other Ethernet devices to compare speeds? 3) Testing with a laptop can be helpful to see if the issue is isolated to your PC. 4) If you're using Ethernet wall ports, ensure the connections are configured properly.
You might want to check the connection properties on both your PC and router. They sometimes struggle to negotiate the correct settings. Also using a tool like iPerf can help to diagnose where the issue lies.
It sounds like there might be an issue with how your devices are connected. If possible, try connecting your PC directly to the modem instead of through the router. Sometimes routers can cause bottlenecks, especially if there's some kind of misconfiguration.
How do I disable that optimization? I don't see any MSI software installed on my system.
