Auto-selecting of traffic

[harddisk]

Hi all.
I got a bit of problems with my WiFi on my Mio A702.
First, only 1/20 connection attempts to a 2m-away AP is successful - how can I obtain debug info from the CSR wifi chip?
Second: If I manage to connect to the internet using wifi, IE and other apps which rely on WM6s connection settings,still connect via GPRS, except the phone part is switched off.
Can I make the WiFi connection like the RNDIS of ActiveSync so it gets the highest preference if connected?

Thanks,
Marco

PS: Is anyone out here familiar with reverse engineering stuff? I'd really like to know how the Flashlight CPL works and how the button switches on the LED (yes, I tried GPIO watching with haret, it crashed the device...)
