I'd had problems with the *wireless* functionality in a Centurylink
(Qwest) "router".  It would crash the router after some period of
operation (I believe a thermal issue taking down the power supply
periodically).  Disabling the radio "fixed" the problem.

Have you assigned static IP's?  I.e., are you sure the router
hasn't reset itself and its idea of what *your* IP should be, etc.?
(i.e., can you bring *another* host online after the crash and
access the router?  Or, has it lost *all* wired connectivity?)

(I've also seen some devices have problems re-autonegotiating
link speeds -- esp Gb-to-Gb)
