Caution about "switching to ubiquity" - not that their product is bad or anything, but they take configuration of their stuff up several notches if you go with their commercial stuff (not sure about the home stuff).

I had considered switching my home wireless system to using Ubiquity APs and other equipment - then I looked into their configuration software. As someone who doesn't hold a Cisco cert or anything of that nature, some of it made me feel really, really stupid (they have a "demo" of their application on their site - to try out the software first). I'm sure it all has a point in a large-scale commercial deployment, but for a home system it seems like massive overkill, and I was concerned that using it and not setting it up properly might lead me to misconfiguring it and opening my network up worse than without using it...
