ifconfig wlan0 up
or
iwconfig wlan0 up
once it's up, u can invoke dhcp to get an address as said before:
dhclient wlan0
thing is, u need ur credentials set before hand with smtg like wpasupplicant (dont remember exact naming); as access points often have passwords and name.
also when using dhcp daemon u can add a v switch to see what s happening
dhclient -v wlan0
1. bring interface up
ifconfig wlan0 up
or
iwconfig wlan0 up
2. set up credentials in wpasupplicant config file
3. get an ip from dhcp daemon
dhclient -v wlan0
also useful to see which ap are around:
iwlist scan
