1.0Gbps full duplex doesn't work

[Redini]

Hi, I've got a problem, I truned off my pc and the 1.0Gbps full duplex doesn't work anymore only 100Mbps works 

Do you know a way to fix it?

Sounds like a damaged cable somewhere. Any cuts or damage to the cable you can see?

Like Lurick said inspect the cable.

 

You can also try any of the following:

Unplug the cable and plug it back in.

Restart your computer.

Check the driver. This could be a bug. Is the manufacturer driver installed?

Disable and re-enable the interface in Windows.

If none of that helps. Try inspecting your switch. Check the duplex. Restart it.

 

You can also try another known good cable.

is your computer off when you get the 100mbps? I know some equipment defaults to 100mbps according to the router

if it is on check your cable, all 4 pairs need to be in use
