Question Ethernet Problem

[Nitsugaaa3]

Hello, how are you? I have an issue with my Ethernet connection: it becomes unstable at high speeds. I have a fiber optic internet connection with a download speed of 1 Gbps. I’ve already updated drivers, reinstalled Windows, and changed the Ethernet cable, but the problem persists. The only way to achieve stability is by reducing the speed and duplex setting to 10 Mbps; at any higher setting, the connection drops after just a few seconds. My motherboard is an ASUS PRIME B650M-A.

Is it unstable during a speedtest?
