I've just committed some important changes to the wpi(4) driver for Intel PRO/Wireless 3945ABG adapters:
http://marc.info/?l=openbsd-cvs&m=118107389909915 Those changes require that you upgrade your wpi-firmware package to version 2.14.3 or your adapter will stop working. The firmware package is made available here: http://damien.bergamini.free.fr/packages/openbsd/wpi-firmware-2.14.3.tgz Also, the default behavior of the driver is now to scan only channels that are listed as authorized in the adapter's EEPROM. You may no longer be able to associate if you were using a channel not in your regulatory domain. Please report any regression you might see directly to me. Damien
