What version of the Proxim driver software are you using? 6.3, 7.1 and 7.2 are compatible with 9.2.2 but apparently the newer firmware doesn't work with some of the older software installs (I have run into this). It will see the card but not do anything like find networks. I have a dual boot with my 1400 with 8.6 and 9.2.2 and different software versions. My newer card works with 9.2.2 but not 8.6
Further, I had connection issues with my Orinoco Silver card until I switched the router to Long Preamble so make sure you have it set to that.
Hope that helps!
