I have been setting up my wireless network and making sure the router works and has at least wpa set. I changed my attenae strength to 50% on my router because 2.4ghz linksys usb adapter picks the signal up fine at 50%.
However, I know for a fact that within 500 feet of me there is not one person with internet access. Do I really need to be worried about someone intercepting my wireless traffic? If they are not close enough to get my signal, obviously I can sleep a little better at night, right?
