Very first ROT (Rule of thumb) for any machine that will be connecting to a wireless network.

yup. Like I said, I didn't poke around on this guy's network. Not my business, and frankly, I might find something that I don't want to know about.

One of the previous posters was right - the other three connections I get locally are "2wire" "netgear" etc. Folks just plugged in and turned on.

I blame irresponsible salesweasels / techs. Lots of ink gets spilled over patching the OS, but quite frankly, most patches are completely irrelevant with a solid firewall and tight wifi security, IMHO.
