I don't have your NIC, but in a laptop I post this in I get: ========================================= $ modinfo iwlwifi filename: /lib/modules/3.18.7- gentoo/kernel/drivers/net/wireless/iwlwifi/iwlwifi.ko.gz license: GPL author: Copyright(c) 2003- 2014 Intel Corporation <i...@linux.intel.com> version: in-tree: description: Intel(R) Wireless WiFi driver for Linux firmware: iwlwifi-100-5.ucode firmware: iwlwifi-1000-5.ucode firmware: iwlwifi-135-6.ucode firmware: iwlwifi-105-6.ucode firmware: iwlwifi-2030-6.ucode firmware: iwlwifi-2000-6.ucode firmware: iwlwifi-5150-2.ucode firmware: iwlwifi-5000-5.ucode firmware: iwlwifi-6000g2b-6.ucode firmware: iwlwifi-6000g2a-5.ucode firmware: iwlwifi-6050-5.ucode firmware: iwlwifi-6000-4.ucode srcversion: FDA022BCC86979326790D21 alias: pci:v00008086d00000892sv*sd00000462bc*sc*i* [snip ...] depends: intree: Y vermagic: 3.18.7-gentoo SMP preempt mod_unload parm: swcrypto:using crypto in software (default 0 [hardware]) (int) parm: 11n_disable:disable 11n functionality, bitmap: 1: full, 2: disable agg TX, 4: disable agg RX, 8 enable agg TX (uint) parm: amsdu_size_8K:enable 8K amsdu size (default 0) (int) parm: fw_restart:restart firmware in case of error (default true) (bool) parm: antenna_coupling:specify antenna coupling in dB (default: 0 dB) (int) parm: wd_disable:Disable stuck queue watchdog timer 0=system default, 1=disable (default: 1) (int) parm: nvm_file:NVM file name (charp) parm: uapsd_disable:disable U-APSD functionality (default: Y) (bool) parm: bt_coex_active:enable wifi/bt co-exist (default: enable) (bool) parm: led_mode:0=system default, 1=On(RF On)/Off(RF Off), 2=blinking, 3=Off (default: 0) (int) parm: power_save:enable WiFi power management (default: disable) (bool) parm: power_level:default power save level (range from 1 - 5, default: 1) (int) parm: fw_monitor:firmware monitor - to debug FW (default: false - needs lots of memory) (bool) ========================================= So in my card I have: "parm: power_save:enable WiFi power management" which is by default disabled. If I wanted to enable this parameter I would need to use a boolean term, e.g. 'true', or 'on', or '1', or 'enable'. Yours would be similar, but the exact parameter would be revealed when you run 'modinfo <your_module_name>' Then call this parameter when you modprobe the module. For example: modprobe -r <your_module_name> modprobe -v <your_module_name> power_level=0 Look at dmesg or syslog to see the result of your incantantion. If this solves your problem you can permanently define such a parameter in your /etc/conf.d/modules. -- Regards, Mick
