I recently installed WS using Fink but I am unable to use it on my Mac mini (Intel) which is wireless connected to the network. As soon as I start capturing the WLAN interface Airport gets disconnected (frees the IP as I'm monitoring this via Growl) regardless which interface I am capturing and which option I en-/disable.

Any ideas?

This is a known problem with OS X on some machines.

Try directly typing the name of the interface in the "Interface:" box in the Capture->Options dialog...

...or try getting Wireshark from Andreas Fink rather than just Fink:

as that version's linked with a version of libpcap that avoids opening wlt devices.
