I found myself going up to my remote location to reboot my router about every month. Fortunately, the remote location is only 8 miles from my house.
So, what I did was to put in a cheap timer between the wall outlet and the router AC plug. I set the timeer to briefly turn off the router and turn it back on at 2am. Seemed to do trick. No more lost connections.
I know there is probably a setting in the router that I could enable, but I don't have quite as much knowledgeknowledge about these things.
Mitch, feel free to chime in.
