Just a question, but did you reboot your N800 after you installed Autoscan?
Mine didn't work either, then I found some docuemtation somewhere that said to reboot after the install.
Now it mostly works.
Cool software.
I am going to go look for the source and try to fix
1: Color problems using Themes.
2: Lockup when trying to open a saved network.
3: Two cancel buttons when trying to load a saved network
