** Description changed: I have no power option for my wireless adapter. Especially when on AC this gets very hot (nearly unusable). In Windows I can lower transmission power which helps. I am under the impression in earlier versions of Ubuntu I was able to do that too (or through some tools). Now it seems to be gone. To my research it seems that the original drivers "ipw3945" have been replaced by newer "iwl3945"? Maybe thats the cause? - How can I switch to "ipw3945" to see if it solves the problem. - Or how can I solve the issue otherwise? - additional Information below: steros@xamos:~$ sudo iwconfig wlan1 power on Error for wireless request "Set Power Management" (8B2C) : - SET failed on device wlan1 ; Operation not supported. + SET failed on device wlan1 ; Operation not supported. steros@xamos:~$ iwconfig lo no wireless extensions. eth0 no wireless extensions. wlan1 IEEE 802.11abg ESSID:"blackhole" - Mode:Managed Frequency:2.412 GHz Access Point: 00:00:00:00:00 - Bit Rate=54 Mb/s Tx-Power=1 dBm - Retry long limit:7 RTS thr:off Fragment thr:off - Power Management:off - Link Quality=48/70 Signal level=-62 dBm - Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 - Tx excessive retries:0 Invalid misc:2 Missed beacon:0 + Mode:Managed Frequency:2.412 GHz Access Point: 00:00:00:00:00 + Bit Rate=54 Mb/s Tx-Power=1 dBm + Retry long limit:7 RTS thr:off Fragment thr:off + Power Management:off + Link Quality=48/70 Signal level=-62 dBm + Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 + Tx excessive retries:0 Invalid misc:2 Missed beacon:0 steros@xamos:~$ lsmod Module Size Used by cryptd 19801 0 aes_i586 16956 3 aes_generic 38023 1 aes_i586 tp_smapi 23023 0 binfmt_misc 13213 1 joydev 17322 0 hdaps 14575 1 thinkpad_ec 14141 2 tp_smapi,hdaps parport_pc 32111 0 ppdev 12849 0 dm_crypt 22463 0 snd_hda_codec_analog 75442 1 snd_hda_intel 24113 2 snd_hda_codec 90901 2 snd_hda_codec_analog,snd_hda_intel snd_hwdep 13274 1 snd_hda_codec snd_pcm 80042 2 snd_hda_intel,snd_hda_codec thinkpad_acpi 73750 0 snd_seq_midi 13132 0 snd_rawmidi 25269 1 snd_seq_midi snd_seq_midi_event 14475 1 snd_seq_midi snd_seq 51291 2 snd_seq_midi,snd_seq_midi_event coretemp 13283 0 arc4 12473 2 pcmcia 39671 0 snd_timer 28659 2 snd_pcm,snd_seq snd_seq_device 14110 3 snd_seq_midi,snd_rawmidi,snd_seq yenta_socket 27230 0 pcmcia_rsrc 18292 1 yenta_socket snd 55295 14 snd_hda_codec_analog,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,thinkpad_acpi,snd_rawmidi,snd_seq,snd_timer,snd_seq_device pcmcia_core 21505 3 pcmcia,yenta_socket,pcmcia_rsrc snd_page_alloc 14073 2 snd_hda_intel,snd_pcm iwl3945 126017 0 iwlcore 148964 1 iwl3945 tpm_tis 13993 0 soundcore 12600 1 snd tpm 21251 1 tpm_tis mac80211 257001 2 iwl3945,iwlcore lp 13349 0 cfg80211 156212 3 iwl3945,iwlcore,mac80211 tpm_bios 13460 1 tpm parport 36746 3 parport_pc,ppdev,lp nvram 14035 1 thinkpad_acpi psmouse 73312 0 serio_raw 12990 0 i915 451033 2 firewire_ohci 31504 0 drm_kms_helper 40745 1 i915 ahci 21591 4 firewire_core 56138 1 firewire_ohci drm 184164 3 i915,drm_kms_helper libahci 25548 1 ahci sdhci_pci 13623 0 e1000e 138627 0 sdhci 22720 1 sdhci_pci crc_itu_t 12627 1 firewire_core i2c_algo_bit 13184 1 i915 video 18951 1 i915 steros@xamos:~$ modinfo iwl3945 filename: /lib/modules/2.6.38-11-generic/kernel/drivers/net/wireless/iwlwifi/iwl3945.ko firmware: iwlwifi-3945-2.ucode license: GPL author: Copyright(c) 2003-2010 Intel Corporation <email address hidden> version: in-tree:s description: Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux srcversion: 77EE951E905F8464CFEDBDA alias: pci:v00008086d00004227sv*sd*bc*sc*i* alias: pci:v00008086d00004222sv*sd*bc*sc*i* alias: pci:v00008086d00004227sv*sd00001014bc*sc*i* alias: pci:v00008086d00004222sv*sd00001044bc*sc*i* alias: pci:v00008086d00004222sv*sd00001034bc*sc*i* alias: pci:v00008086d00004222sv*sd00001005bc*sc*i* depends: iwlcore,cfg80211,mac80211 vermagic: 2.6.38-11-generic SMP mod_unload modversions 686 parm: antenna:select antenna (1=Main, 2=Aux, default 0 [both]) (int) parm: swcrypto:using software crypto (default 1 [software]) - (int) + (int) parm: disable_hw_scan:disable hardware scanning (default 1) (int) parm: fw_restart3945:restart firmware in case of error (int) ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: linux-image-2.6.38-11-generic 2.6.38-11.48 ProcVersionSignature: Ubuntu 2.6.38-11.48-generic 2.6.38.8 Uname: Linux 2.6.38-11-generic i686 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.23.
