well, that was rather confusing. From what i read, a lot of the serious problems with Wi-fi from the early 2000s has now been overcome with more strict standards and certification from the Wi-Fi Alliance, http://www.wi-fi.org/organization.php, although this doesnt necessarily mean all wi-fi devices are certified. But the general majority are? So probably a good way to protect your security is to find out what devices are certified. Only products that complete Wi-Fi Alliance interoperability certification testing successfully may use the "Wi-Fi CERTIFIED" designation and trademark:
Another thing is to make sure you have a truly random passphrase of 13 characters (selected from the set of 95 permitted characters) - there is a list of the top 1000 SSIDs to avoid as well.
Despite all that though, from looking at the history of Wi-fi, what security works now, may well not work in a year or so, as people seem to be constantly finding new weaknesses.
