Hmmm,Say you need to move your computer do you drag the Cable/Line around with you,still connected to the Modem or Wall outlet?...You can either unscrew or unplug your Modem or Line connecting you to the Internet,Or you might unplug from your Router or Modem...I mean I actually unplug The cable from my Ethernet Card after each use and before each startup I plug it back in,Yes it does take an extra minute to download the files each day from Comcast but since I have been doing this I have missed only one days Internet connection and that was when att and Comcast made the switch as to useing ZA that is a very smart move...
