Hi Don, Perhaps use a design such as a Lindenblad or a Quadrifillar Helix; you don't have enough space to put one on the laptop, so it's got to go on the AP.
Of course, you lose 3db going circular->linear. Maybe that's the problem. They'd rather double the radios and put one vertical, and the other horizontal (or put 3 in there with 802.11n)...
