This is a *very* cool unit, but good luck if you need any technical support. My Linksys arrived from Amazon yesterday, and although the simple things were easy to configure, I have a slightly more complicated question for technical support. I spent 20 minutes on hold on day-1, with my call answered by an "operator". No call back, so I tried again on day-2. 2.5 *HOURS* on hold, then finally another "operator", who promised a priority response. 7 hours later I tried again, with a promise for a call back within 30 minutes. Guess what, it's been another 2 hours. Apparently the big sticker on the box which advertises "24x7 Support!" is the amount of time it takes to get a human.
