I have recently installed a rb1100ahx2 I'm using at home on a gigabit fibre connection. Everything works well however my speedtest results are almost 50% less than what I usually ran on my stock Huawei ISP router. I understand this routerboard should cope fine with the gigabit fibre link and I have seen other posts where users where getting 900mbps plus on this router. I'm hitting a max of about 600mbps down and 400 up. Could this be a config issue?
