I have a Cisco access point, and a couple of wireless cards. I've been meaning to get it installed at home. My main motiviation was to enable me to use my laptop in the front room, be able to surf, and not to have a 10baseT cable strung across the floor. Looking at the manual, it all looked far too hard, so it got put on the tuit pile (that list of things I'll do when I get a round tuit).
Well yesterday, I got around to trying it - man is it easy. I just plugged it in, powered it up and it worked. No configuration - it just worked. Of course, there's no security, and anyone with a wireless device passing the front of the house could make use of it, but it is easy. The security aspects, however, are somewhat scary!
