>>WEP is actually worse than useless, as it gives you a false sense of security. Switch to WPA or WPA2 instead. If anyone you know is still using WEP, do them a favour and let them know.

>At home, when I look at the available connections, only my front neighbour has a password (forgot the protocol using) but then there are like 10 un-protected connections available, you should come and offer your services door to door for setting the networks :)

Most sites I've visited can see 3 or 4 other wireless networks, of which 1 or 2 are typically unsecured. If I went door-to-door or wardriving I'd be able to sell network upgrades 24/7/365 ;)

Another PSA: never attach to an unknown, unsecured wireless network. Bad guys have been known to set up "honeypots" and sniff all traffic that passes through them - an easy way to quickly gather a lot of confidential information :/
