This is Linksys' familiar blue-and-gray box. I have one of them that loses
its configuration settings occasionally. I'm suspecting there may be a
backup battery inside that is weak. And in any case, if I can't actually
use it, I'd like to see what's inside.

Any ideas how to open it up? There are no screws (not even under the rubber
feet). It looks as if the case snaps open -- but how?
