I currently have the 2200BG part in my laptop which uses the same driver, but only supports B and G. I been using it exclusively ever since the v0.14 driver allowed associating to access points that are hosting multiple wireless networks (ala wireless VLANs) like we have in the Guru Labs office.
Today, May 18th 2005, the new driver v1.04 was released along with new firmware. One of the highly anticipated new features is the support for monitor mode. This also the operation of wireless sniffing tools such as kismet.
Many other bugs were fixed as well. Hopefully Fedora Core v4 will ship with this version of the driver.
