wellmeij- the Sony Alpha 100 is very aggressive about turning off the (CF) card slot, even when the camera is seemingly on. This is why you are not able to upload from within that body. It does happen that the card is on long enough as you are taking photos to capture access point information for geotagging.
As others have suggested here, there is likely another access point that is not being picked up within the Sanyo, and it is that other access point that has been previously mapped by skyhook's WPS system.
You can make this better by following the instructions at this link to get your home AP mapped:

PS: we don't list the A100 on our incompatibility list, as it only lists SD based cameras, and we haven't comprehensively tested CF models.
