Controversial 'six-strikes' copyright alert system launches in US

MAC filtering and turning off broadcast of SSID can be helpful to keep the technologically challenged from poaching your wireless (which is most people). It will only slightly slow down someone who knows what they are doing. Something else to take into consideration is range. Unless you live in a condo or apartment, there won't be many people in range of your wireless. Use the best security you can, but no reason to be paranoid.

How is someone "technologically challenged" going to poach your internet if you have a reasonable WPA/WPA2 password in place? Your premise makes no sense. It simply isn't a good idea for a variety of reasons. Here's a link from Robert Moskowitz, a security expert from ICSA Labs. He shows that not only is this an ineffective security measure, but it can also degrade network performance.

Debunking the Myth of SSID Hiding

You must have missed the "Use the best security you can" part of my post. Some people still use some older equipment that does not support WPA. I feel they should upgrade their gear but I am not the one spending the money.

I didn't miss that. Let's run with that. Because we're still using the "technologically challenged" barometer as your baseline of the people you want to keep out. So, in that case, pick a "strong" WEP key. Who's going to guess it? Not the technologically challenged, that's for sure. But seriously, with "N" routers available now for as little as $20, there's no excuse for not upgrading. If you don't have $20 to spend on security, you probably shouldn't be spending money on an internet connection. Food might be a better idea.
