To get a little more specific, I have tried this with the XP wireless manager on and the Cisco stuff off, and vice versa. I suppose the most obvious step is to change 340 AP firmware to 12.04, but I am curious if anyone has seen this already before I make the change. It looks like updating the firmware on the AP will require that I update the firmware/drivers on some, if not all of my other 802.11b clients, so if this fix will not help my new a/b/g client I will avoid it for now.
