Why would my router randomly become unreachable under WPA2?

Why would my router randomly become unreachable under WPA2?

We just switched ISPs from AT&T DSL to Comcast. AT&T had its own (horrifically bad) router, but with Comcast we're using my 802.11n Airport Extreme. Unfortunately, the router randomly becomes unreachable. I'm still shown as "connected", but I can't ping the router anymore. This doesn't appear to happen when I've got WPA2 off, though I can't confirm for sure. Any idea why this might happen, or what I can do to prevent it? I would really prefer to be using WPA2 if at all possible.

It turned out that the router was on the other side of the kitchen wall behind the stove. Large metal objects completely wreck the signal-to-noise ratios. Moving the router so that it wasn't right next to the stove fixed the problem.
