I will also add that Using a Linksys router with 4 year old firmware in a basement (game room) on the other end of the house, my iPhone, iPod touch, Droid Eris, 'Windows XP' laptop and iPad all work without issue.
One question - Why was the wife or anyone else using the "family PC" not arrested? Or are only males arrested for child porn?
That is a good question. Why should one assume that the wife wasn't the one viewing the footage or more over that the children weren't viewing pornography of other children the same age as them?
It's a poor workman who blames his tools.
