Hey there, just settled into a new home. I’m using the standard Xfinity modem/router setup for gigabit connectivity with plenty of data allowance. The router supports Wi-Fi 6 and consistently delivers speeds above 1Gbps to the main gateway. I’ve run my setup with a Cat6 cable to an unmanaged PoE switch in the office, and switched cables multiple times—including a brand new one. When testing on a laptop or another PC, I see speeds ranging from 800 to 900 Mbps, which matches my expectations. However, on my main PC (Aorus Z370 Gaming 7), I’m only getting around 250 Mbps, even when using both Ethernet ports and QoS disabled. I’ve reset network settings several times without improvement, but I’m still figuring it out myself. Previously, my connection was stable at 600 Mbps, so maybe the issue lies with the Xfinity gateway? I’ve tried different routers before and still experienced similar speeds, but my other devices perform well. Thanks for taking the time to read this—I appreciate your thoughts!
It seems the issue isn't with the Gateway or Modem, as consistent slow speeds would affect all devices. You've confirmed the modem/gateway isn't the cause by testing directly connected equipment, so the problem likely lies with your computer or networking hardware.
I get that perspective. It seems the issue isn't with the networking gear, as most of it is brand new. That points to the motherboard possibly being the source of the problem. It's interesting that the network connection on the motherboard behaves differently after moving, while other components function normally.
What is this? It seems completely illogical, isn't it? How did you reach such a conclusion?
I’d suggest reinstalling your actual LAN drivers, though that sometimes helps but isn’t always effective. You might also consider a BIOS update if you haven’t installed the latest one—it could resolve the slow performance issue. Unless you’ve tried other options, I don’t have any other ideas to propose.
In theory, nearby transfers could reach 2.5Gb, but the available internet speed would be restricted by the plan, resulting in a maximum of 1Gbps.
