Realtek Gaming 2.5GbE Family Controller not responding at 100Mbps
It seems the issue is with the decoder itself. When connecting the PC to the main ISP, only 1GB appears, which suggests a problem with the decoder. Some users think it's a QoS limitation, but there’s no way to adjust it on the Deco X20. No clear solution found yet.
Disable Advanced EEE (Energy Efficient Ethernet) and Gigabit Lite, which limits speeds to 500 Mbps. Adjust your Speed and Duplex options to Auto Negotiate or 1 Gbps full duplex.
