neighborhood? i assumed it was like a password, but when i used it the lock symbol next to my network disappeared, and now i'm worried that my network is fully unlocked. i had a regular password set up before, but the security settings kept kicking my laptop off so i had to downgrade from WPA+PSK [TKIP] + WPA2-PSK [AES] to WEP (and clearly, i have no idea what any of this means). basically...is the lock gone ONLY FOR ME because i used the key, or did doing so fully unlock my network for everyone?
