What I normally tell people to do when setting up a WiFi access point... 1. Set up a PSK of at least 30 random lower case letters. 2. Switch off WPS. (I used to tell people 20 random characters using mixed case letters, digits and symbols. Using lower case letters only is easier to type on a phone.) Is a WiFi access point set up this way vulnerable to this new attack? So many times I've been warned that "WPA2 has been cracked" but when reading, it turns out that someone has just built a system to perform brute force dictionary attacks.
