I have a gigabit router (TP-LINK C9) and a on board network card supporting gigabit (Intel 82567lf gigabit), yet when I plug in the network cable, all I see is 10 Mbit connection.
How do I set the networking speed to 100 Mbit or 1 Gbit?

- Right click your network icon in the taskbar and select network and sharing center
- Select your Ethernet connection
- Select "Properties"
- Select "Configure"
- Select "Advanced"
- Find Speed and Duplex, it may be on autonegoation, force 1 Gbps Full Duplex
- Press OK
- If you experience cable missing or undetected network, reconnect the LAN cable, or try another port on your router
You should now have 1 Gbps.

If the cable quality is not up to par, gigabit Ethernet will often fall back to 10 Mbps rather than 100 Mbps. As such, it’s worth checking that your cable is cat 5e or better, the connections are secure, and your cables aren’t damaged.

For me it was the order of cable ports, I had recently switched the computer end of cable with the router end. Plugging it back in original order fixed the issue.
