Hey I just bought a new router and configured it! I checked the range out and it was amazing! but when I did a speedtest it maxed only upto 10mbps, whereas my internet plan is 75mbps. I did a lot of research in the gateway page and i came to know that it was becaus of the Duplex settings. it was set to automatic and I changed it to 100mbps full duplex. But even now the probllem isn't solved. When i check the internet logs. it shows that intenet is connected to 10mbps full duplex. Please Help!

Thank You
