The iwlwifi-3945-1.ucode is the one shipped with Ubuntu's 2.6.24-21-generic kernel sources (md5sum: 26d10014b09439dc5a8573c2a6f85b0a ). And, as mentioned in the subject, 2.6.27 or 2.6.26 work perfectly fine. Oh, and the .config: CONFIG_IWLWIFI=y CONFIG_IWLCORE=y # CONFIG_IWLWIFI_LEDS is not set CONFIG_IWLWIFI_RFKILL=y # CONFIG_IWLWIFI_DEBUG is not set # CONFIG_IWLAGN is not set CONFIG_IWL3945=m CONFIG_IWL3945_RFKILL=y CONFIG_IWL3945_SPECTRUM_MEASUREMENT=y # CONFIG_IWL3945_LEDS is not set # CONFIG_IWL3945_DEBUG is not set Any ideas? Patches to test? Thanks! Best, Dominik
