Hi all, I have a Dell XPS M1530 with an Intel IWL3945 wireless card. On power-up/reboot it sometimes works, sometimes doesn't. I can find no pattern at all, success does not depend on the machine being hot/cold rebooted, powered up from shutdown, hibernate, suspend or any other usual thing. I don't use the wireless-rf kill switch at all.
I've googled, read the comments in the source and read heaps of howtos without success. Ideas anyone? On failure, the exact error message in dmesg is: Sep 17 18:04:48 nazgul [ 5.304072] iwl3945: Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, 1.2.26kds Sep 17 18:04:48 nazgul [ 5.304072] iwl3945: Copyright(c) 2003-2008 Intel Corporation Sep 17 18:04:48 nazgul [ 6.229313] iwl3945: Detected Intel Wireless WiFi Link 3945ABG Sep 17 18:04:48 nazgul [ 6.230984] iwl3945: Error: saturation power is -1, less than minimum expected 40 Sep 17 18:04:48 nazgul [ 6.230984] iwl3945: Invalid power index Sep 17 18:04:48 nazgul [ 6.230984] iwl3945: initializing regulatory failed: -5 Sep 17 18:04:48 nazgul [ 6.237253] iwl3945: probe of 0000:0b:00.0 failed with error -5 On success, the dmesg output is: Sep 17 18:37:52 nazgul [ 4.576768] iwl3945: Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, 1.2.26ks Sep 17 18:37:52 nazgul [ 4.576768] iwl3945: Copyright(c) 2003-2008 Intel Corporation Sep 17 18:37:52 nazgul [ 5.490369] iwl3945: Detected Intel Wireless WiFi Link 3945ABG Sep 17 18:37:52 nazgul [ 5.603457] iwl3945: Tunable channels: 13 802.11bg, 23 802.11a channels Sep 17 18:37:52 nazgul [ 5.609491] phy0: Selected rate control algorithm 'iwl-3945-rs' The hardware: [EMAIL PROTECTED] ~ $ sudo lspci | grep -i wireless 0b:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02) Kernel: 2.6.26-gentoo Config: [EMAIL PROTECTED] ~ $ zgrep IWL /proc/config.gz CONFIG_IWLWIFI=m CONFIG_IWLCORE=m # CONFIG_IWLWIFI_LEDS is not set CONFIG_IWLWIFI_RFKILL=y # CONFIG_IWL4965 is not set CONFIG_IWL3945=m CONFIG_IWL3945_SPECTRUM_MEASUREMENT=y CONFIG_IWL3945_LEDS=y # CONFIG_IWL3945_DEBUG is not set [EMAIL PROTECTED] /etc $ grep -i iwl /etc/mod*conf /etc/modprobe.conf:alias wlan0 iwl3945 -- alan dot mckinnon at gmail dot com
