Brian Want to be clear not saying anything about this board yet just units I have seen in the past. Bottom line is WISP need to do there own testing as will we and report things as we find them. I am interested to see what everyone finds.

There is a good opinion I was looking for. That is why I posted this so someone could tell me whats wrong with it. :) [EMAIL PROTECTED] wrote: >I am sure Charles and some are you are thinking the same thing I am on >the 400mW unit, something just does not add up when manufactures are >doing the same power and the cost of the card is the more then the cost >of the full unit!
