crispy how recently have you tried cracking wep? because weak ivs no longer exist with neweer hardware had losts of fun trying to crack my own ap after about 4 days of constant traffic i still had no weak ivs and airsnort had not broken into it for home use though i would recommend firewall, no dhcp, wep, wpa mac filtering, and hiding the ssid. for a buisness i would look at adding a vpn over the network and haveing them completely seperate from most computers on your network. eg in a dmz controled by an up to date smoothwall/or something similar box
