Realtek gbe family controller throttled at 100mbps
Sebastian Wright
I recently sent my laptop to service and I believe they changed the motherboard. Before that I could get 1000mbps, but now the connection is stuck at 100mbps as you can see in the screenshot:
The router and the cable remained the same. I tried 2 different versions of drivers, including the last one on the realtek website. I performed a clean install of the windows, the speed won't budge.
EDIT: The laptop is an ASUS GL752VW
I know that most people think it's the cable since that solved the issue in other similar questions, but I tried other cables and the problem persists and as I said, I had 1gbps connection before I sent my laptop to service with the very same cable I use now.

I had similar issues. I tried to connect PC to a modem and got 1 Gbps. Connecting through a router (tried 2 different kinds of routers) and got only 100 Mbps. With all the plugging in and out, the PC suddenly registered 1 Gbps. So to anyone who is going through this. I really suggest not only swapping cables but plugging in-out a few times. Make sure there is no dirt etc. in the socket. Cables that consistently gave me 100 Mbps suddenly gave me 1 Gbps. also, I had a situation where a particular cable went from 1 Gbps to suddenly drop to 100 Mbps...
