50% of Belgian Wifi networks are unprotected

According to a survey (ZDnet.be) from BIPT (Belgian Institute for Post and Telecommunication), half of the Belgian consumer wifi networks are unprotected. Actually, I don't think this is a bad figure. I know that some years ago it was about 33%. I didn't say it was a good figure either since it still needs a lot of improvement. The article doesn't state if WEP is considered as good protection or not since it would only take one minute to crack it.
