Geez... Just remembered when I switched to an all-WPA setup after WEP was cracked and one laptop couldn't make the transition because of an ancient 802.11b implementation. Good times!

Here's a different perspective...

WPA and WPA2 are still safe, experts call BS on NVIDIA cracking - The Tech Herald

"These guys are forgetting two things- first; this method doesn't work AT ALL against an enterprise installation (RADIUS) of WPA," wrote Rich Mogul, discussing the comments made by GSS.

"Second, as the original article added as an update, this attack only speeds up brute forcing. Use a long, strong passphrase for your WPA key and you're fine," Mogul added.

Robert Graham of Errata explains this in more depth. "At worst, all this really means is that you have to add one extra character to your WPA password to achieve the same level of security. Password cracking is exponential. Each additional character in a password makes it 100 times more difficult to crack (assuming you use upper and lower case, numbers, and symbols)."
