I also put the router on a timer this year after reading it on this site (lots of great ideas). I set it to reboot once a week. It has worked so far this winter.
I have an outdoor nestcam pointing back at the house so I can see the entrance. It dings my phone when someone walks towards the cabin like an "early warning system"
.
I have an older Dropcam inside that sometimes also needs to be rebooted. We bought a wifi switch that I plug the camera into and if the camera goes out I can cycle the power from the app on my phone.
