Very well explained.According to the datasheet on your particular router, it's 4 times the speed of 802.11g (which is 54 megabits per second). So 4 x that is 216 megabits per second. Converting that to megabytes, comes out to approx 27 megabytes per second...MAXIMUM. Considering that ethernet at best gets around 80% efficiency, you can really only count on 27MB/s x .80 = 21.6 megabytes per second. And the speeds of devices slow down when they get further away from the router...so unless you are right next to the router with no interference you aren't going to hit 100% of these speeds.
So, when you say that you see speeds of 19.5 megabytes per second on your computer...that's about right. Those other figures are showing you cached speeds from within Windows and are simply inaccurate.
