How To Stop Blinking Wifi LED on Dell E6510 in Ubuntu

Ubuntu 1

In this article, we will delve into the steps required to stop the blinking WiFi LED on a Dell E6510 laptop running Ubuntu. This can be a distracting issue for many users, but fortunately, there is a way to resolve it.

Quick Answer

To stop the blinking WiFi LED on a Dell E6510 in Ubuntu, you can modify the configuration file for the wireless module. By adding the line "options iwlagn led_mode=1" to the file, you can disable the blinking LED and have a steady LED behavior. Restart your laptop for the changes to take effect.

Understanding the Issue

The WiFi LED on your Dell E6510 may blink continuously when you are connected to a wireless network. This is due to the way the wireless card’s driver is configured in Ubuntu. The blinking LED indicates network activity, but it can be distracting and unnecessary for many users.

Prerequisites

Before we begin, ensure that you have administrative access to your Dell E6510 laptop. You will need to use the terminal, which requires administrative privileges for this process.

Solution Steps

Step 1: Open the Terminal

The terminal is a command-line interface that allows you to interact directly with your Ubuntu system. You can open the terminal by navigating to Applications > Accessories > Terminal or by pressing Ctrl + Alt + t.

Step 2: Open the Configuration File

Enter the following command in the terminal:

gksudo gedit /etc/modprobe.d/intel-6200-iwlagn-disableblink.conf

This command does a couple of things:

  • gksudo is a command that allows you to run graphical applications with administrative privileges.
  • gedit is a text editor in Ubuntu.
  • /etc/modprobe.d/intel-6200-iwlagn-disableblink.conf is the path to the configuration file for the wireless module.

If the file doesn’t exist, it will be created. If it already exists, it will open in the text editor.

Step 3: Modify the Configuration File

In the file, add the following line:

options iwlagn led_mode=1

Here’s what this line does:

  • options is a keyword that specifies module options.
  • iwlagn is the name of the module. This may vary depending on your wireless card and Ubuntu version.
  • led_mode=1 is the option that disables the blinking LED. The 1 value represents steady LED behavior.

Save the file and exit the text editor.

Step 4: Restart Your Laptop

After saving the changes, restart your laptop for the changes to take effect.

Conclusion

This solution is specific to Ubuntu 11.04 (Lucid) with kernel series 2.6 and the Intel Centrino Advanced-N 6200 wireless card. If you are using a different Ubuntu version or a different wireless card, refer to the relevant documentation to find the appropriate module name and option.

If you’ve followed these steps correctly, your WiFi LED should no longer blink continuously. If the issue persists, it may be a hardware-level behavior that cannot be controlled by the operating system. In this case, a small piece of tape can be used to cover the LED and prevent it from being a distraction.

Remember, always be careful when modifying system files and only do so if you are comfortable with the changes you are making. If you are unsure, seek help from a professional or a knowledgeable friend.

Can I use this solution for a different Dell laptop model?

This solution is specifically tailored for the Dell E6510 laptop. The wireless card and configuration may vary for different Dell laptop models, so it is recommended to refer to the relevant documentation or forums specific to your laptop model for a solution.

Will this solution work for a different operating system?

No, this solution is specifically designed for Ubuntu. The steps and commands mentioned in this article may not be applicable or work for other operating systems. It is recommended to refer to the documentation or forums specific to your operating system for a solution.

What should I do if the configuration file mentioned in step 2 doesn’t exist?

If the configuration file /etc/modprobe.d/intel-6200-iwlagn-disableblink.conf does not exist, running the command mentioned in step 2 will create the file. If the file already exists, it will open in the text editor. You can proceed with modifying the file as mentioned in step 3.

How can I revert the changes if I want the WiFi LED to blink again?

To revert the changes and allow the WiFi LED to blink again, you can either remove the line options iwlagn led_mode=1 from the configuration file mentioned in step 2 or comment it out by adding a # at the beginning of the line. Save the file and restart your laptop for the changes to take effect.

Is there any risk involved in modifying system files?

Modifying system files can have consequences, and it is important to proceed with caution. Ensure that you have administrative access and are comfortable making changes to system files. It is recommended to back up any important files before making modifications. If you are unsure or uncomfortable with the process, it is best to seek help from a professional or a knowledgeable friend.
