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)...

Greg,
You got me thinking about going circular! I am wondering how you build an omnidirectional Circular antenna? What am I missing as I don't want my router or my notebook to be directional?

------------------snip--------- Pretty much every Wi-Fi antenna I've ever seen is linearly polarized. The "diversity" antennas are two separate antennas, usually one vertical and one horizontal, with separate cables going to two radios. Going circular would seem to be a no-brain improvement for the Wi-Fi crowd, but I think I've only seen one vendor do
it.
Enjoy the new toy,
