Alan, I'm assuming you're referring to:

Re. WEP: Google for "airsnort" and "WEPcrack". These tools, among others,
permit WEP keys to be cracked in a matter of minutes on a busy network.

Re. MAC filtering: MAC addresses are easily spoofed, if you have
hardware and drivers that support it. I imagine many wireless cards
and drivers do. Many wired Ethernet cards certainly do.

Re. turning off broadcasting: I'm not sure about this one, but I expect
the reason it's not useful is that as long as there's some wireless
traffic for an intruder to examine, he'll be able to get into your
network. So not broadcasting only makes you safer if you don't use
your wireless network for anything else, either.

Cheers,
