What Options for the config_iwlwifi_leds in Linux Config File
When configuring your Linux system, especially for devices using Intel’s Wireless WiFi Link (iwlwifi) drivers, you might come across the config_iwlwifi_leds option in the Linux config file. This option allows you to customize the behavior of the LED indicators on your wireless adapter. In this article, we will explore the various options available for the config_iwlwifi_leds and how they can be utilized to enhance your user experience.
Understanding the Purpose of config_iwlwifi_leds
The config_iwlwifi_leds option is part of the iwlwifi driver configuration file, typically located at /etc/modprobe.d/iwlwifi.conf. It controls the behavior of the LED indicators on your wireless adapter, which can be useful for monitoring the status of your wireless connection. By modifying this option, you can customize how the LEDs behave under different circumstances, such as when the device is connected, disconnected, or in various modes of operation.
Options for config_iwlwifi_leds
Here are some of the most common options available for the config_iwlwifi_leds:
| Option | Description |
|---|---|
| ledtrig_connect | Turns on the LED when the device is connected to a network. |
| ledtrig_disconnect | Turns off the LED when the device is disconnected from a network. |
| ledtrig_wifi | Turns on the LED when the device is in WiFi mode. |
| ledtrig_wimax | Turns on the LED when the device is in WiMAX mode. |
| ledtrig_radio | Turns on the LED when the radio is enabled. |
| ledtrig_tx | Turns on the LED when data is being transmitted. |
| ledtrig_rx | Turns on the LED when data is being received. |
These options can be combined to create a custom LED behavior. For example, you can use ledtrig_connect and ledtrig_disconnect to indicate when the device is connected or disconnected from a network, and ledtrig_wifi and ledtrig_wimax to indicate the mode of operation.
Configuring config_iwlwifi_leds
To configure the config_iwlwifi_leds option, you need to edit the /etc/modprobe.d/iwlwifi.conf file. Open the file in a text editor and add the desired options, separated by spaces. For example:
options iwlwifi ledtrig_connect=1 ledtrig_disconnect=1 ledtrig_wifi=1 ledtrig_wimax=1
This configuration will turn on the LED when the device is connected, disconnected, or in WiFi or WiMAX mode.
Testing Your Configuration
After configuring the config_iwlwifi_leds option, you need to restart your system or reload the iwlwifi module to apply the changes. You can use the following command to reload the module:
sudo modprobe -r iwlwifisudo modprobe iwlwifi
Once the module is reloaded, you should see the LED indicators behave according to your configuration.
Conclusion
The config_iwlwifi_leds option in the Linux config file provides a convenient way to customize the behavior of the LED indicators on your iwlwifi-based wireless adapter. By understanding the available options and how to configure them, you can enhance your user experience and easily monitor the status of your wireless connection.
