hmm. I tried out all settings and theres no other possibility than deactivating wpa and wep and only secure the wlan with an macfilter :/ And there is a second problem with the mac-changing.
HM! And I thought about a second method. Why don't we create an app that just forwards the whole gps datastream and acts as a USB-GPS-Receiver for a program on pc (to use it with a laptop and software that is already cracked )
