Simplifying the task of setting up a wireless LAN in your home has been the recent goal of most of the 802.11 hardware vendors. Unfortunately, at least from my vantage point, they are not achieving that goal (even though they make claims to the contrary).
One major vendor put out a full-scale marketing pitch to show that the end user need only press one button to have the entire home network configure itself. In theory, that sounds great. After hearing the pitch, I was sold. That was until I saw the working (and I use the term "working" loosely) demo at a trade show.
Note that I've been termed "demo buster" by more than one vendor. But they trusted me anyway, and asked me to push the button that would configure the network. Unfortunately, when I pushed the button, nothing happened. No configuration, no instant setup, no data transfer, no nothing. Not even a blinking LED. The embarrassed marketing guy claimed that it was beta software, and there must be glitch somewhere. I'm still waiting for him to get back to me.
