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.

    Hello, I just want my NIC to be able to go up to 1000 mbps since it is my internet speed, but it won't go upper than 100 mbps for some reason. I just want to know if I should send the laptop back to service or there are some faster options I have regarding the problem. – Boanta Ionut Jan 6 '18 at 16:10

    the laptop model i quite new, it's a gaming asus rog with gen 6 cpu. I checked under ethernet properties and at speed and duplex it is selected 1.0 gbps full duplex, so the NIC is compatible. It just doesn't want to work properly. – Boanta Ionut Jan 6 '18 at 16:40

    Possible duplicate of Realtek NIC running at 100Mb/s rather than 1000Mb/s – Jason Bristol Jan 6 '18 at 18:58

    Cables, cable,s cables! I have a bad cable right now doing the same thing; different hardware though. I usually start with the cables, then move onto troubleshooting other stuff if the cable checks out. – Damon Jan 7 '18 at 5:09

I too had similar issues... connect PC to modem and I get 1GBPS, connect through router (tried 2 different kinds) and get 100Mbps. With all the plugging in and out, the PC suddenly registered 1Gbps. So to anyone who is going through this. I really suggest not only swapping cables... but plugging in-out a few times, maybe even make sure there is no dirt in the socket etc.. because cables that consistently gave me 100mbps suddenly gave me 1 gbps. also I had a situation where a particular cable went from 1 Gbps to suddenly dropping to 100mbps...
