As I understand it, Windows allows 64 ASCII character passphrases though--in violation of the spec. That has led some networking equipment manufacturers to build to the "Windows standard" and therefore allowed some Windows-only shops to configure their wireless LANs in a broken manner. The MCSEs say their network is fine as all the Windows notebooks can connect. Nokia says their Maemo devices are fine as they exactly follow the specifications. Users find themselves rapidly balding in a strange, patchy, painful way.
