I know very little about computers and am kind of intimidated by them so I was actually very amused when I bought my computer and router and the clerk explained to me that if I ever had a problem getting a wireless signal, to unplug the cable modem and then unplug the router wait 10 seconds and plug them back in. I've had to do it a couple of times, and even though it's nothing I alwyas feel intensely proud of myself for some reason.
