Yep, just about every word of what I just posted above is good for wireless networks only. If you're using wireless onl your network (and I would imagine you are if you have the same model as me) then the instructions are valid. If you're using an exclusively wired network then there's not a lot there that you need to worry about.
Sorry about that.
