A little while ago my dad mentioned a person in their car parked in our neighborhood. I figured that the guy was wardriving, and what with all the unsecure wireless networks around here I decided to enable wpa with a pre-shared key. Ever since I have been experiencing network problems. My old pc will get disconnected 1 time every half hour or more. My laptop seems better, but I have been having several problems trying to connect to the network, and it usually takes 10 minutes or so till I get a connection that works. Did I setup the router wrong or something? Is tehre a less problematic way for keeping any idiot with a wifi enabled laptop out of my network?
