Hmmm. I have 100Mbps FTTH. Using my Asus RT-N66U 5Ghz band Wifi I get around 50Mbps with speedtest, but I can get more if I disable WPA2 personal security. With ethernet cable it gets crazy

Wow that's great.
Comcast just upped my speed by 66% for free so I get around 30 Mbps. Which is more than enough ..
