Hi Pat, It's a good guess, but I don't think that's the case, in part because the 6235 is a 2x2 MIMO module— the antennas are MAIN/AUX, not WIFI/BT. I actually did encounter an Azurewave module which was set up that way, and both portions came up on the Gigabyte motherboard— I would have kept using that module, but there was a supply availability issue, the wifi performance was very poor, and I was interested in using a MIMO part.
