Hey everyone, I just upgraded my internet plan to 750/50 and thought it’d be perfect timing to start laying LAN cables around the house. Before diving in, I ran a quick test using my PC connected to the router with an extra cat 5e cable. On Speedtest.net, the speeds came back around 400Mbps. My PC connected via Wi-Fi 6 was hitting about 650Mbps, and the router’s internal tests showed low numbers in the 700s. I’ve swapped out cables, ports, and even disconnected everything except the test PC, but the results stayed consistent at roughly 400Mbps. A cable tester confirmed my cables were fine, and the computer shows a 1GB connection speed. There’s also a NAS connected through LAN, with file transfers being much faster over the LAN than Wi-Fi—around 250Mbps vs. 800Mbps. To sum it up: Router internal tests show 720Mbps for PC to Speedtest.net via Wi-Fi 6, 650Mbps over LAN, 400Mbps via Wi-Fi to NAS, 250Mbps LAN to NAS, and 800Mbps LAN to LAN. My setup uses an Asus RT-AX56U router and a powerful PC with updated drivers. I’ve checked all settings and haven’t found any obvious bottlenecks. Connecting my PC directly to the NBN box caused a BSOD, so that part isn’t working. I also tried a spare AMD mini PC over LAN, which gave similar results. It seems the issue might be with the router itself. I’m leaning toward upgrading to a new modem/router that’s known for strong LAN performance.
No changes made to your motherboard manufacturer or the actual network card vendor.
Use the drivers straight from Intel. Based on what I've seen, most issues stem from poor drivers, and getting them directly from the manufacturer typically fixes it about 99% of the time.
Fascinating. I'm definitely going to give it a try! I tested it on another machine—specifically an AMD mini PC using Linux—and it performed similarly over the network, so I think the problem isn't there. I'm hoping it'll be as easy as a driver update! I'll let you know once I've given it a shot.
I agree with your approach and tried the same setup on another machine. For maximum performance, consider using a modem/router like the TL-ER605 for the internet connection and an existing Asus router for Wi-Fi. Since you're in Australia, expect speeds above 1000Mbps consistently, so future-proofing isn't a major concern right now.
