You probably want to look at wpa_supplicant (in particular man wpa_gui), or any other network manager type of application would do (wicd, network manager, wifi-radar) which allows you to enable/disable access points for automatic connection to them. Alternatively, a less practical approach would be to set up config_wlan0=( "null" ) in your /etc/conf.d/net.wlan0, which will not allow your wireless card to obtain any address. Or, you can play with dhcpcd options like so: dhcp_eth0="release nogateway nosendhost" which means that it will not bind to any wireless router as a gateway. -- Regards, Mick
