You might need to use miopocket sd free version, also you need to enable the registries for your wireless card. Please read through the miopocket readme , there is a paragraph talking about this. Another choice is to use sd free 1.7 http://www.cyberfans.cn/bbs/thread-11829-1-1.html to unlock your MIO, it has a couple of SD wireless drivers and applications built in. Once you unlock mio, just plug in your card and go !
