Speed issues on LAN and internet after restarts Crashing download rates following system reboots
I've been facing this annoying problem for several days. My ISP offers a 400mbps connection, but it consistently stays around 380-400mbps. This speed isn't related to my 2700X Asus Hero VII crosshair Wi-Fi or the Intel 1Gb LAN port. Even after a fresh install, everything remains stable. I'm testing my internet again—down 400mbps, up 40mbps. After rebooting, I ran a speed test and got 50-60mbps. My wife's computer on the same switch still shows 400mbps. I tried DNS changes, cleared cache, updated drivers, even reinstalled Windows, but nothing seems to work. It's currently around 90mbps at best. Recently, after a full Windows reinstall, it returned to the original slow speeds. Anyone know what's happening?
It appears your PC is reverting back to a half-duplex 100Mb connection. Open settings, then Network & Internet, select Change Adapter Options, right-click the Ethernet adapter, go to properties. Locate Internet Protocol Version 4 (TCP/IPv4), click it and choose configure. Proceed to advanced settings, adjust Speed & Duplex to 1Gbps full duplex, and re-test. It should be set to Auto Negotiate at this point.
I’ll test when I get home tomorrow. I think I might have misconfigured it to gigabit duplex, but who knows. Probably I made a mistake. Most of the time my speed on Speedtest starts at 200-300+ and then drops quickly to 100, then slowly goes down to 50-60. Maybe auto negotiate is causing it to suddenly settle at 100 Mbps instead of what I see. I wonder if it’s actually running around 100 Mbps rather than the 50-60 I’m getting. Do I get this right?
Tried it out. Configured for full duplex 1gbps. Same result. Something odd is happening—the LAN driver is displaying "ethernet internet saucer," which is the name of my Ubiquity Wi-Fi dish downstairs. It’s not connected to Wi-Fi since the adapter is off. Usually it would show something like "Ethernet Network" or similar, never the name of another device on my network, especially not my Wi-Fi router. This is strange. I inserted a poor-quality drawing that mapped my network. As you can see, this PC and its switch don’t connect with the Wi-Fi dish, so I’m confused about why they’re using the same name for their LAN network as my Wi-Fi AP.
I focus on actual performance in everyday use, not just speed test numbers. On platforms like Steam, my real-world download speed depends on the game, network conditions, and server availability.
