Debian sarge (amd64) does not come with the software needed to enable WPA authtentication on wireless lans. before you are tempted to give up and go with WEP security, read about the security flaws here. Security of the WEP algorithm: http://www.isaac.cs.berkeley.edu/isaac/wep-faq.html you will need to download wpa_supplicant. Get the latest release. (Please check for card compatibility) http://hostap.epitest.fi/wpa_supplicant/ the Broadcom drivers needs to be installed via ndiswrapper. It does not have native drivers.

How to use WPA with ndiswrapper http://ndiswrapper.sourceforge.net/mediawiki/index.php/WPA as stated in the article, you might need to configure pairwise / groupwise negotiation. I used the config. below file: "/etc/wpa_supplicant.conf" network={ ssid="*******" scan_ssid=1 psk="********" key_mgmt=WPA-PSK pairwise=TKIP group=TKIP proto=WPA } then just two more commands: (make sure your driver is loaded and configurable via ifconfig for me ifconfig wlan0 shows up so...) 1. wpa_supplicant -Dndiswrapper -iwlan0 -c/etc/wpa_supplicant.conf 2. usually you might be using DHCP : dhclient wlan0 Happy Browsing !
