Would the Gentleman/woman with the Wireless Please Step Forward

Some assclown around our house has been playing with a new Linksys wireless
router for the last couple of days. I say playing because it turns on and
off at irregular intervals and appears to be unencrypted. I say assclown
because, well, I'm a mean bastard reaching for dramatic effect.

This marks the moment where I have to start taking wireless security a
little more seriously. Up until now I WEP encrypted and thought nothing of
it, resting assured in the notion that nobody around our house could spell
wireless (kidding). But now I need to take note. First comes the wireless
node. Then comes the google search on "sniffers." Then comes airsnort.
And before you know it everybody in town knows that my password is...
well... I digress.

I'm going to slap some MAC address filters onto our home network. We've
got about nine machines connected around the house and I want to make sure
only they have access to... well... stuff.

And I was enjoying the technology gap.
