I just updated to 150 using the Hitron modem which I've already been using for 1 year with no problems. I get great speed on my iphone and my laptop when plugged in (150+) but my wifi speeds on my laptop are bad. My laptop supports N but only at 2.4 ghz. My windows network connection says I'm running at 65mbps but a speedtest shows max 32mbps. I tried changing channels, turning on 20/40 and turning off qos but I still cant get above 35mbps. Any other ideas?
