Sure, and I'm not complaining! Just trying to figure out how to make this thing even more useful. Some of us could go into the hardware-detection code, and find out more about diagnostics and remedies. Writing it all up in the wiki here, and eventually provide tools for download.

This can't be cutting edge stuff, but most of us won't need that, either. We can safely limit our ambitions to hardware where there are well documented, open solutions.
Maybe a place to start, is to uppdate the wiki for 6.x? And a wireless FAQ for 6.x - like you have contributed so well to for 5.x?
