I have an ASRock H61M-DGS and i just upgraded my network speed from 100mbs to 1gb, but my computer is stuck at 100mbs. I tried pluggin the cable into my laptop and it works at 1gb. I tried different cables but none worked. I use a tp-link WR1043N but i dont think that would be the problem since it worked on my laptop. I also tried uninstalling and installing the driver but that as well didnt work.
Edit: I use the same cable when i change from laptop to pc.
