I'm not posting a full screen shot with location, latency information (48ms - actually kind of awful) and protocol (IPv6) so you'll just have to take my word for it, but the initial speed test - while we were still on the phone with Level 5 tech support after he fixed our download speed - shot up to a comparatively decent 578.75mbps:
I want this screencap framed. Better yet, I want this download speed.
Alas, it was not to be: subsequent tests show speeds as high as 150mbps (entirely on the kitchen laptop, which has the wireless N spec - the prototype of wireless N, in other words - and yet still it flies) to as low as the usual 30-45mbps on other devices around the house, but hey, I can look at this screencap, at what was for a few seconds, and dream.
It's not an unusual speed in South Korea, after all. And obviously it's possible here. The price, though, probably isn't within reach for most of us.
