A little off the wall perhaps, but ...

I have a cable modem and a router for a wireless home network. Is it a good or a bad idea to turn it off at night and during the day when we're all at work or school? Or should I leave it on 24/7.

I was thinking that leaving it on constantly makes me more vulnerable to hackers, not to mention wasting electricity. (Though I'd guess the amount of electricity used by a cable modem and a router is probably pretty trivial. Still, every little bit helps.)

When I have turned it off and turned it on again, it takes several minutes for it to go through its little dialog with the cable company and get me connected to the Internet again, which is annoying but not a big deal.

Anyone know any good reasons one way or the other?
