Am I missing something? I have Vista Business installed on my LS800. I'm trying to set up an ad-hoc network between my laptop (Vista Ultimate) and the LS800. I created a WPA secured ad-hoc network on the laptop and while the LS800 could see the network it stated the adapter was unable to meet the requirements for the network. I then tried to create the ad-hoc network on the LS800 and noticed that WPA was NOT an option in the drop down.

I started with the Intel 2200BG drivers from the Motion site. I then updated the drivers to the Intel 2200BG drivers from the Intel site hoping this would fix the issue. Same result.
