Do any of you unplug (turn off the power to the powerbar) your Airport Extreme overnight? Does it harm it at all turning it on and off? It always stays so warm even when not in use that I wonder if it woudn't be wiser to shut it down overnight to prolong it's life expectancy. Also, if it is so warm, it's obviously consuming needless power for an 8 hour stretch that it's not in use at all. Just curious what others are doing. Also, my cable modem is on the same powerbar. If I power them both down and power them both up with the same switch on the powerbar could you see that causing any problems? My first wireless router and I am a bit unsure of myself here. Thanks for any help,info.
