This was a Teletronics WLAN card with firmware 2.06. I don't remember where this was done. This was the only card that I've ever had that was sooooo sensitive. I sent it back to the factory to get it tested so I could find out how low of a signal it was picking up. Turns out it was not really picking up any useful signal. If you can pick up a lot of signal in a basement or down in a hole, check the card in several more locations. If it still always shows something out there you have a bad card.
