The GUI that is used to connect to the WNDA3100 is abysmal. Once you've installed the software, you'd think it would be as simple as scanning for networks, connecting to a network, and saving the settings as a profile. WRONG. Clicking an "Apply" button after selecting your pre-configured profile pops up a window that says "Validate Settings"... followed by no connection to the network, even though it can be seen with 94% signal strength. The software looks to be done in Adobe Flash, complete with fade-in and fade-out effects, so everything takes a long time to start or complete. In fact, trying to run the latest software package (v1.3 as of June 2, 2008) resulted in a BSOD on my laptop. That might have been due to low memory, but it shouldn't require that much power to connect to it in the first place.

At this point, I may sell the WNDA3100, take a slight loss and buy a different wireless adapter instead.
