Yes, at 11Mb/s that is a reasonable number. Note: I have not personally
tested this extensively.

Some of the commercial APs include dual dipole antennas. You _may_ get
better range from them. I have no actual evidence to substantiate this,
it's just an opinion.

Nope. Better antennas.

Our rate control stuff may not be giving you what you want. I've been
meaning to revisit that code but haven't gotten around to it yet.

I've had reports that the AP side code doesn't rate control at all, but I
haven't confirmed it myself.
