ipwctl —
configure Intel PRO/Wireless 2100 network adapter
The ipwctl utility controls the operation of Intel
  PRO/Wireless 2100 networking devices via
  ipw(4) driver.
You should not use this program to configure IEEE 802.11
    parameters. Use ifconfig(8)
    instead.
The options are as follows:
  - -iiface
- Display adapter's internal statistics.
- -iiface- -r
- Display the radio switch state (on or off).
The firmware, loaded automatically, is not shipped with
  NetBSD; install the
  pkgsrc/sysutils/ipw-firmware package. The original
  archive is available from Intel at:
  http://ipw2100.sourceforge.net/firmware.php?fid=3.
