Router not picking up modem?

Try a hard reset to factory default settings, and then configure it as if it was brand new according to the instructions you got from your ISP. It is possible a glitch in the power line cause it to "lose" it's configuration. Sometimes this kind of response can be caused if you have a "brownout" where the power does not go off completely, just goes low in voltage. There is a point when a computer is losing power that the CPU goes insane and since the CPU is god, it can do anything in that condition, such as write to memory that it shouldn't and wipe out it's own programming. Look in the documentation for how to perform a hard reset. No guarantees, but it IS worth a try...
