+rep if it connected with no security (after the reset), then maybe move up one step, security-wise, to WEP with an easy-to-remember password. If that works, then you could try WPA2. baby steps. also, the easiest/best thing to do, imho, is to hide your network's name (make the SSID non-broadcasting). Neighbors won't see it, won't try to connect. If there's a car parked out front with a big can-tenna sticking out the window, you're in trouble, but just in the neighborhood you shouldn't need super-duper security. no matter what security you set up, if someone wants in/on badly enough, they'll get in.
