Re: WEEPING FOR WEP

I use WEP at home, even though my house is far enough from the road to
make it rather difficult for someone to jump on my network.

Even if someone decided to hide in the woods at the edge of my yard with
a laptop they're more likely to be eaten by a bear, sprayed by a skunk,
or chewed alive by mosquitoes than collecting enough packets to crack
the WEP key, so WPA or LEAP would be overkill.

Like you said, measurement of risk.
