For configuration of wireless without NM, you need iwconfig (in case no security 
or WEP), and wpa_supplicant in addition in case of WPA.

You would do something like this (suposing wlan0 is the wireless interface):
$ iwlist wlan0 scan
- shows you available networks (SSIDs) with signal strength
$ iwconfig
show wireless configuration

to connect :
iwconfig wlan0 mode Managed
iwconfig wlan0 essid <your SSID> 
iwconfig eth0 key s:<yoy key>    (specifying WEP key)

For WPA, you need to create configuration for wpa_supplicant and run the 
program.

More info:
man iwlist
man iwconfig
man wpa_supplicant
