Wireless Throughput Confusion

I recently bough a Netgear R6200 Router which states it can reach 1167 Mbps (300 + 867) throughput. I also have a Linksys WMP600N dual adapter on my PC. Both are 801.11N as well as G,B,A ready. My ISP is providing 6/1 Mbps internet service. So my question is what should my speed indicator (through the Network Sharing Center interface) read as a max throughput? Currently it says 300 (+/-) Mbps so where is the other 867 (or somewhere in-between) bandwidth? Conversely, if my thought processes are aligned with the stars, and all I am getting is a max of 6 Mbps from my ISP, why is my wireless status telling me its 300 Mbps? CONFUSED Novice!!!
 
That 300 + 867 is the AGGREGATE bandwidth, when you consider all the available wireless bands. But that doesn't mean any single band/client is capable of reaching those numbers. IOW, if you’re using wireless N, you have a theoretical limit of 300Mbps, but when using AC, it’s a theoretical limit of 867Mbps. But you can’t add them together and expect 1167Mbps because you can't use both bands on any single client at the same time.

As far as the speed indication in Windows, those estimates (and bad estimates at that) are based on signal strength, not measured performance. It’s really no better at indicating your actual throughput than the 3-bar wifi indicator on your typical smartphone. In fact, it would be more useful and honest if Windows actually used the wifi icon. But they’ve opted for the “visual appeal” of a speed indicator because that’s what desktop users expect.
