I have read a paper that indicates NDIS 5 support is mandatory for adaptors that will be used for Hot Spot access. I don't believe the PCM352 has this - but appears to work in UK HotSpots I have evaluated.
Latest wizard, 1.1, says it is installing NDIS driver 8.3.
Explanation required about different NDIS 'varieties' and what they provide; and whether Aironet supports them, please.
