Slow LAN connections, typical Wi-Fi performance. 1 Gbps connection. Possible hardware problems?
Slow LAN connections, typical Wi-Fi performance. 1 Gbps connection. Possible hardware problems?
Hey! A few days back I received a new router, an AX1500 from TP Link. My issue is that during speed tests on my Wi-Fi with a 1Gbps connection, everything seems fine and I get average download speeds between 300-550 Mbps. But when I connect to the LAN ports, my Windows PC only manages about 50 Mbps, which is really low. I’ve used CAT6 and CAT5e cables, tried various ports, but the problem persists. Even with the same internet cable, a different Mac I tested could reach up to 800 Mbps on speed tests. My setup includes a Ryzen 7 2700X, Nvidia 2070, ASUS ROG Crosshair VII HERO X470 ATX, and G.Skill Trident Z RAM (32GB, 3200MHz). The PSU is Corsair 1000, and other details don’t seem to matter much. I’ve tried multiple fixes—switched cables, ports, settings, changed IPs, adjusted QoS, and even reset the router and PC—but nothing changes. I’m starting to think there might be a hardware or configuration problem. I feel like I ruled out network faults since everything else works. The LAN port on my MBO seems broken? Why can’t I get speeds similar to the old router where I averaged around 250 Mbps? I’ve done a lot of troubleshooting, but I’m exhausted and really need help. Thanks for your time!
Check another device connected to the same router port for normal performance. If it works, the issue likely lies elsewhere. Visit the Asus website and update the NIC/ethernet driver. If problems persist, adjust the speed of the MB NIC in the network settings to 1Gb. This suggests a 2.5Gb device, so the router may not be negotiating properly.
