I have a network using WPA-PSK + TKIP and I have seen articles like on Tom's hardware about how to crack it but I am not particularly confident its *that* insecure if you configure other options and use very long complex passwords. I have run Kismet, airsnort, etc, etc to try to crack my own key and after 18 hours was unable to get enough IV's to get anywhere.
I am using a group key interval that changes frequently, SSID is indeed broadcast but the password strength is extremely strong. Antenna gain on my wireless ap's are cranked down to my building only with particularily weak signal > 10 ft from the outside. I also have physical security patrolling 24/7 on the perimeter of this property (security guards).
Feel free to lambast me and tell me I'm wrong but I don't believe WPA-PSK + TKIP is all that easy to crack- if at all with proper passwords and other efforts.
Of course intend to go 802.1x when available but this is my current option. If there is strong reason to believe that this is easily compromisable I would love to know this as I will shutdown my AP's until stronger auth is available to me.
