Hi,
I bought the Motorola SURFboard® SBG900 prior to using my Eye-Fi card. I setup the card and had some initial trouble connecting to the AP. It turned out to be a MAC address filter that I had enabled on the router. Getting the Eye-Fi card MAC, adding it to the AP, and reconnecting fixed my issue. I'm using the Nikon D90 and an Eye-Fi Explore card which I've subsequently upgraded to include geo-tagging.
