I have a fios router to which I want to add Airport Extreme to. Why? Because I will then be able to connect my printer to both operating systems, without the hassle of setting printer sharing, which is easy from Mac to Windows but, a lot more difficult or so it seems from Windows to a Mac using OS X 10.6.7 and Windows 7. What I have yet to find is will this really work without any big hassles. Or will not work right off the bat?
