Was 802.11n a failure?

I only tested using download speedtest to many other variables involved with PC hardware and I don't know what would be a reliable benchmark program. G=25 N=115 on 2.4 or 5g no change Tested using a WNDR4000 With Intel 6235 I typically use 5g and the rest of the family uses 2.4 My reported connection rate is maxed at 300 5g and 144 2.4 I have no interest in using channel bonding in 2.4 unless I'm bored and want to watch the numbers change all day. At some point increased wifi (AC) speed is fluff and hype. The only home use for it that makes sense is to use as a bridge to a entertainment center, but even that is dependent on location. When I beta tested Comcast Docsis 3 several years ago I told them great Idea but unless you reconsider your service cap at 250 gig a month why bother, who needs it for sending e-mails. I now have to send tomorrow's insults today because it's so fast. I spent months trying to find a Sony Laptop with a Intel 6300 & i7 and never could find one that I could afford. I settled on a 6235 with a i5 and changed out the hard to a Seagate 750 hybrid drive. Win 7 pro 64 takes 8 seconds to PassWord screen and 7 seconds to complete boot up, no swirling mouse pointer, ready to go. I do own a R6300 and it's new beaming is something that may make me purchase a USB Client since I do have USB 3 ports. More than you asked for, Bill
