For those to lazy to read the article, FBI recently cracked wep 128 in 3minutes, I have cracked wep64 on a celeron 400 laptop in 15, not using the newer tools either, and I have seen how to crack wpa, once the packets are captured you don't need to stay on or near the network, just go away and crack the wpa key, if someone wants to get connected they will, if they try really hard, I would suggest just enable layers, wpa/wep128 and mac filtering and then monitor the connection, make sure the neighbours aren't still connecting, if they have cracked in, then they are good enough to crack almost anything bar putting the ap on a software router with vpn end point, this way you need to connect to the vpn to have access to your network and the internet, and if you use openvpn, with 2048bit encryption, if they try a brute force hack it will take them a few thousand years...
