EAP-PEAP & windows mobile

Hello,

I am trying to implement a wifi access with AP1131AG aironet and radius ACS 3.3.
I would like to connect a PSION Teklogix PDA ( with windows mobile 2003 ) the issue is with the microsoft PEAP client is completely inestable. I have tried with the funk client odyssey and it works great !

Does anybody have any experience of connecting trough PEAP authentication with the microsoft windows mobile client ? Maybe the radius should be upgraded ?

Thank you
