Wireless card for an access point

[Omnutia]

Dear all,
I am building a home server and would like to add a wireless card in order to have it act as an access point. I have tried using a Zd1211 based USB wireless dongle to no avail. Could anyone recommend a wireless card (PCI or USB) that they know will work properly in Ubuntu without too much hassle?
Failing that, which chipset should I look for when looking for a card?

Thank you for your time.

on chipset i can't help you with. but perhaps the most popular sold one, common sense i know, but hey its bound to be supported

why dont you get something like a minitar AP and just plug it into your ethernet connection, no driver to load and it runs linux.
