Title, I'm on a Gigabyte B560M DS3H AC. I updated Windows, I updated the Realtek Drivers. I'm 100 mbps Half Duplex. But still, my LAN was slower than before, and I also would get "Ethernet Cable is Disconnected" despite the cable being tightly seated in the slot. I used to get 90 mbps on Ookla, and now I'm only up to 9 mbps. I'm wondering if there's something wrong with my drivers or my LAN Cable if it's really not compatible anymore. Realtek's LAN driver is Ver. 10.50.511.2021, Windows Version is 10.0.19044
