I told you there was no good reason to secure your access point! Bruce Schneier Blazes Through Your Questions - Freakonomics - Opinion - New York Times Blog
Q: Is there any benefit to password protecting your home Wifi network? I have IT friends that say the only real benefit is that multiple users can slow down the connection, but they state that there is no security reason. Is this correct?
A: I run an open wireless network at home. There’s no password, and there’s no encryption. Honestly, I think it’s just polite. Why should I care if someone on the block steals wireless access from me? When my wireless router broke last month, I used a neighbor’s access until I replaced it.
