madwifi atheros card, wifi basics


so i have madwifi installed for my d-link (Atheros AR5212 802.11abg NIC). how do i switch so my internet traffic goes through that card instead of my wired connection? im not sure everything is installed correctly, this is the output from ifconfig

iwconfig, ifconfig and dhcpcd are your freinds

you can set you essid and encryptions keys like so with iwconfig (as root)
# iwconfig ath0 essid mywireless
# iwconfig ath0 key 123456789ABCDEFG1234

then if you have dhcp get yourself an ip address by using dhcpcd like so
# dhcpcd ath0

if you don't have dhcp you can manually give yourself an address
# ifconfig ath0 inet 192.1681.10.123 netmask 255.255.255.0 up
