And there was me trying to keep it simple so that Mr SPIT could a) understand what I was talking about and b) end up with a single box handling his connection(s).
Which is why I didn't start pontificating about adding ethernet switches! I also agree with mixture about their use.
Regarding wireless I also agree that wired is faster and less of a problem on many levels but it does work, is useful and with basic security enabled how likely is it that the average person is going get hacked and lose anything of value?
