iwconfig works with wlan-ng too for displaying info, but may not support
everything (does not currently display and cannot set WEP keys on the
fly). For example:

> /usr/sbin/iwconfig wlan0
wlan0 IEEE 802.11-b ESSID:"private-name"
          Mode:Managed Frequency:2.462GHz Access Point: 00:06:25:53:B1:CE
          Link Quality:71 Signal level:118 Noise level:0
          Rx invalid nwid:0 Rx invalid crypt:1818 Rx invalid frag:0
          Tx excessive retries:0 Invalid misc:0 Missed beacon:0
