Hello All,
I hope someone can help me out with this.
I currently pay for 300Mbps/15Mbps internet. I am able to achieve these speeds via wired network connection from my Asus RT-N56U router on two computers; one desktop and one laptop. My other desktop computer is only able to achieve a maximum of 140Mbps/15Mbps using a Cat 5e network cable. I have tried several different things to troubleshoot this slow speed (listed below). The only thing I have not yet done is re-install Windows 7. If anyone has any other ideas please let me know.
