Hi
You only need to configure two files:
Code:
/etc/rc.d/rc.inet1.conf
/etc/wpa_supplicant.conf
In fact you could even delete /etc/rc.d/rc.wireless.conf because all it's configuration items are available in /etc/rc.d/rc.inet1.conf anyway. The file is being kept for people who want to tie their settings to the MAC address of their wireless card.
If your card shows up as wlan0 then running
Code:
/etc/rc.d/rc.inet1 wlan0_start
manually will start the card. Slackware will run this on boot so that you do not have to run it manually every time. This
wiki link has some background info for setting up WPA in Slackware.
