AFAIK it will only work on clients already connected to "open networks". If a client is connected to a WAP* Secured network, it wont connect to a rouge AP with the same SSID.
The user has to explicit choose to connect the the "open" rouge SSID... In my view, this is not likely to happen.
One solution is to install the module "site survey" and capture enough "IV's" to crack the WPA* hash... (recommend onlinehashcrack.com - under 8 caracters its free)
(Take a look at this video)
Once you have cracked the WPA hash, set up a rouge AP, as a secured network, using the cracked key.
This should now make your targets (the wifi clients) connect to your AP if the signal is stronger.
Whats missing.: I would like this option built ind to the Wifipineapple, so its not a manual process... as far as i can tell (correct me if I'm missing somthing here) it is not possible to set a WPA key on the secondary WLAN adapter on the wifipineapple... only on the management part.
This is in my oppinion, a critical function - hope it will come in the near future.
