Description of problem: I'm using a HP Presario 3803TX laptop with a Intel 3945 wireless card. It has a power switch. If I boot into system with this power switch off, I will never be able to connect to the wireless card even if I turn on it. Version-Release number of selected component (if applicable): 2.6.35.6-48.fc14.x86_64 Actually, this problem exists for a pretty long time in all kernels I've used. How reproducible: Always Steps to Reproduce: 1. turn off the wireless power switch. 2. turn on computer, boot into system, log in. 3. trun on the wireless power switch. Actual results: The wireless card does not work. The network manger and iwconfig shows the wireless is "disabled" or "power off". Expected results: It should be turned on. Additional info: I have tried to enable it using iwconfig, but it fails. ###### results by iwconfig: ###### $ iwconfig wlan0 wlan0 IEEE 802.11abg ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=off Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off # iwconfig wlan0 power on Error for wireless request "Set Power Management" (8B2C) : SET failed on device wlan0 ; Operation not supported. ###### results by lsmod: ###### Module Size Used by deflate 2143 0 zlib_deflate 18639 1 deflate ctr 3813 0 camellia 18447 0 cast5 15888 0 rmd160 7984 0 crypto_null 2878 0 ccm 7799 0 serpent 19133 0 blowfish 8450 0 twofish_x86_64 5247 0 twofish_common 14366 1 twofish_x86_64 xcbc 2631 0 cbc 2953 0 sha256_generic 10175 0 sha512_generic 4788 0 des_generic 16583 0 cryptd 7111 0 aes_x86_64 7758 0 aes_generic 26908 1 aes_x86_64 ah6 5788 0 ah4 5132 0 esp6 4943 0 esp4 5210 0 xfrm4_mode_beet 2160 0 xfrm4_tunnel 1955 0 tunnel4 2665 1 xfrm4_tunnel xfrm4_mode_tunnel 1895 0 xfrm4_mode_transport 1455 0 xfrm6_mode_transport 1519 0 xfrm6_mode_ro 1308 0 xfrm6_mode_beet 1969 0 xfrm6_mode_tunnel 1996 0 ipcomp 2089 0 ipcomp6 2122 0 xfrm_ipcomp 4305 2 ipcomp,ipcomp6 xfrm6_tunnel 4009 1 ipcomp6 tunnel6 2516 1 xfrm6_tunnel af_key 27035 0 vboxnetadp 4967 0 vboxnetflt 13626 0 vboxdrv 1758075 2 vboxnetadp,vboxnetflt sunrpc 201180 1 cpufreq_ondemand 9278 2 acpi_cpufreq 7329 1 freq_table 3955 2 cpufreq_ondemand,acpi_cpufreq mperf 1481 1 acpi_cpufreq ip6t_REJECT 4279 2 nf_conntrack_ipv6 18078 2 ip6table_filter 1687 1 ip6_tables 17481 1 ip6table_filter ipv6 286249 59 ah6,esp6,xfrm6_mode_beet,xfrm6_mode_tunnel,ipcomp6,xfrm6_tunnel,tunnel6,ip6t_REJECT,nf_conntrack_ipv6 fuse 61363 7 uinput 7368 0 arc4 1449 2 ecb 2119 2 nvidia 10213047 31 iwl3945 118175 0 snd_hda_codec_conexant 41923 1 iwlcore 195683 1 iwl3945 mac80211 228732 2 iwl3945,iwlcore snd_hda_intel 24399 4 snd_hda_codec 86743 2 snd_hda_codec_conexant,snd_hda_intel cfg80211 134709 3 iwl3945,iwlcore,mac80211 snd_hwdep 6392 1 snd_hda_codec snd_seq 53791 0 snd_seq_device 6191 1 snd_seq snd_pcm 80190 3 snd_hda_intel,snd_hda_codec sky2 46473 0 r852 10070 0 sm_common 4276 1 r852 nand 32055 2 r852,sm_common nand_ids 4258 1 nand nand_ecc 3936 1 nand hp_wmi 6087 0 snd_timer 19892 2 snd_seq,snd_pcm rfkill 17622 3 cfg80211,hp_wmi i2c_i801 11088 0 mtd 18231 2 sm_common,nand snd 63968 15 snd_hda_codec_conexant,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_seq,snd_seq_device,snd_pcm,snd_timer soundcore 6576 1 snd serio_raw 4640 0 iTCO_wdt 11256 0 snd_page_alloc 7559 2 snd_hda_intel,snd_pcm i2c_core 26900 2 nvidia,i2c_i801 iTCO_vendor_support 2610 1 iTCO_wdt wmi 8138 1 hp_wmi joydev 9737 0 microcode 18548 0 sdhci_pci 7871 0 sdhci 18464 1 sdhci_pci video 21637 0 firewire_ohci 21170 0 mmc_core 64113 1 sdhci firewire_core 45817 1 firewire_ohci output 2253 1 video crc_itu_t 1563 1 firewire_core
That could be an issue with platform driver hp_wmi. What do you get for $ rfkill list If hp_wmi blocks the switch you could try: # rmmod hp_wmi
I have the same problem with different hardware. My laptop is a Dell Inspiron 6400 (also iwl3945). $ rfkill list 0: dell-wifi: Wireless LAN Soft blocked: no Hard blocked: yes 1: phy0: Wireless LAN Soft blocked: no Hard blocked: yes After removing dell_wmi the rf kill switch work ok. $ rfkill list 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no Even when is working properly i got a few error messages from dmesg. When i turn it off: [ 455.727740] iwl3945 0000:0b:00.0: Card state received: HW:Kill SW:On [ 455.729627] keyboard: can't emulate rawmode for keycode 240 [ 455.729649] keyboard: can't emulate rawmode for keycode 240 [ 455.732193] iwl3945 0000:0b:00.0: Not sending command - RF KILL [ 455.732204] iwl3945 0000:0b:00.0: Error sending REPLY_RXON: enqueue_hcmd failed: -5 [ 455.732214] iwl3945 0000:0b:00.0: Error setting new configuration (-5).

As a workaround i added blacklist-wmi.conf to /etc/modprobe.d with: install dell_wmi /bin/true install wmi /bin/true blacklist dell_wmi blacklist wmi A few questions: - is this the right solution? - what i missing when disabling wmi? - is there a way to fix the keyboard error? (setkeycodes <something> 240?) - is there a way to fix the Tx power issue?
I forgot: this is happening with Fedora 15 i686 too: kernel 2.6.38.8-32.fc15.i686 iwl3945-firmware 15.32.2.9-5.fc15.noarch
Pablo, can you file a separate bug for the dell_wmi case. It may be a related issue, but it's in a different module, so needs tracking separately.
Pablo issue is tracked in bug 732029
After booting into the system with turned off wireless switch, please do this: # yum install rfkill # rfkill list # rfkill event turn on the switch exit from rfkill events logger (ctrl-c) # rfkill list and provide here console output. Thanks.
