Ah, in this case WMM is doing what it's supposed to unfortunately: It prevents a download (the speed test) from consuming 100% of the bandwidth, to keep a large portion set aside for multiple streams and more importantly to make sure things like VoIP phones, streaming webcam chats, or just plain streaming video (NetFlix, etc, from another computer) won't hiccup during the download/speed-test from your computer.
Also, anything above 54MBit/second is "N" mode, so if you still get better than 54MBit w/ WMM disabled on the router you are getting the benefits of N-mode in the form of better latency, etc. It may be that the router supports a slightly lower maximum speed w/ WMM disabled than enabled, I've seen stranger limitations occur.

That makes perfect sense although you'd think if no other program with a higher priority was active then the current download program (browser) would get all the bandwidth.
I will try and set my browser as having highest priority in the router settings and see if that helps. Again, thank you for your insight.

Well, the issue is if all the bandwidth is granted to any one thing when everything is idle, there's no way to support letting something else 'join in' afterwards because they'll have delays even getting the initial connection started, etc.
And there's no way to know when this second person might show up, thus... it keeps part of the bandwidth set aside.
