It’s pretty easy for someone who’s determined to hack into your WiFi network nowadays, even if you think you’re safe with WPA encrypted password protection and all the rest. WEP security is all but useless, and yet people still rely on it to keep others from accessing their wireless LAN. The annoying thing is that anyone camping on your bandwidth costs you money, as well as using up your bandwidth allowance, which is a double whammy, let alone the security issues.
