Sorry for not or mis-understanding. I also have a Realtek PCIe GbE Family Controller on a MSI B450-A PRO ATX AM4 Motherboard with integrated network adapter and under Properties W/10 says 1000/1000 (Mbps) and under Status it says 1.0Gbps and https://www.speedtest.net says 116.00 Mbps Download and 5.79 Mbps Upload and is connected to the Router/Modem directly via Ethernet. But my plan is only good for 100 Mbps Download. I had a higher tier for a while and although it got 200 Mbps Download yet the upload was the same.
Then I went to one of my tv sites and started to download a program. This is what I call the real world speed and it's what matters to me. When we had DSL I would tell my next door neighbor that I was only getting 2MB/sec down and he would tell me that I must have some kind of a problem because his speed was 10 times faster than mine. We were getting the same speed, just describing it differently.
