Hardware :: AEBS Dual Band Versus 1 Signal?

After the announcement of the Simultaneous Dual-Band II, I've taken an interest in getting the most out of my version. However, I've been noticing signal issues especially when using the 5 ghz network. I have it set to "wide channels", multicast rate of "High", deselected "closed network" and "interference robustness", and the transmit power at 100%.

I've adjusted the position of the router to avoid potential sources of interference, and when I go to select a network with the airport icon at on the task bar, my 5.0 ghz network is never at full strength. In fact, it rarely shows more than 2 bars. As I type this post, I am literally six feet from the AEBS and I have only 3 bars showing.

When I view the statistics within the Advanced Tab in the Airport Utility I am only showing a rate of 65 mbps on the b/g/n (2.4ghz) network and 270 mbps over the 5.0 ghz n network.

Does anyone have any idea how to get this thing going at full performance? When I'm in the adjacent room, I am rarely able to get over 200 mbps. I know a wall is in the way, but my apartment is modestly sized and it is very disappointing that the signal is this weak on this lil thing - especially given the fact that I've had it for just about a month and its been updated to address the signal issues.
