I had a problem similar to that at my house, except that the interval between resets - by unplugging the power connecter for my main router for a few seconds - was a few days, and getting shorter and shorter.
Apparently, a small trickle current was polarizing the hull plating (sorry, too much Star Trek: Enterprise
on the brain) I mean putting a static charge on the ethernet jack of the router that was connected to the Actiontec.
The problem began shortly after the cable company had done work on the telephone pole my downlead comes from - but it doesn't really matter what the source of the trickle current is.
I solved the problem for good by grounding the case of one of my splitters or duplexers - it doesn't matter which, since they're all connected via the coax's shielding, but I grounded the one nearest my router.
Try attaching a wire from the case of one of your splitters or duplexers - one or more of them may well have a grounding terminal, but one of the mounting holes would probably work as well - to the the grounding hole of a known good three-prong AC outlet. You can use an outlet tester (the kind that lights up to indicate that it's properly wired) to be sure.
See if that cures the problem.
