I got a WPC11 V3 (prism3) working. But I took the card back for a Dlink 650+ which works but the graphing does not.
Note: this 650+ card is not a prism card. It is a TI ACX100 card that supports 22mbps when connected to another TIACX100 bases system. US Robotics has an identical card called the 2210.
When I say graphing wasn't working, it was just a solid purple bar at -90 and no red or green like my Prism3 card had.
