Wifi talk can be found
Here.
I'm a little confused, you seem to be trying to install a CF wifi card in an Axim that already has wifi, Why?
If you have installed new drivers for a different wifi setup it will probably override the original wifi setting, thus causing your inbuilt wifi to not start.
A hard reset would certainly fix it, but that is a bit drastic to start with.
Go into the settings of the wifi, start/settings/connections/wlan utility
and check what network card it is trying to use.
