Introducing Cox Gigablast

I got the gigablast today.  8 feet away from the wireless current model Apple Time Capsule router, about as good as it gets, I'm seeing mb values in the 100s or so with wireless N in my few year old iMac.  The service bombed out in the speed test several times to discontinue the test on both speediest.net and the cox speed test webpage.  I've seen also the speed crawling along at 12 mb painfully watching the speed test to complete.  My wireless ac through my iPhone 6 pluss when used with wireless ac router has done as well as 100smbs down to about 30mbs with variance for no particular reason other than it seems glitchy.
