Sudo apt get install madwifi tools

The apt-get command is responsible for installation, removal, and updating of software in our system. A good analogy is to think of your computer as a factory and the apt-get command as the manager in that factory who is responsible for the installation of new equipment, removal of equipment that is no longer needed, and update desired equipment to their latest versions, while maintaining records of the equipment names and versions which are currently present in the factory.

In the screenshot below I am trying to install an app named gedit, which is basically a text editor. Your output might look a bit different than mine, but the important things to note here are the first 2 lines. So naturally, the first thing the manager will do is to have a look at the documents given by all the equipment manufacturers and information required regarding what are the parts available with each of them which are necessary to build the conveyor system.

The next thing the manager need to do is to go ahead and do the research of what are the parts needed for the conveyor and make a shopping list. You cannot install a belt for the conveyor, before installing the rollers and the conveyor motors, because a belt depends on the presence of a conveyor motor and a roller to do its job, hence roller, sensors and motors are dependencies for a conveyor belt!

Then once apt-get knows what software to download and where to download them, apt-get tells us what additional packages will be downloaded and installed and how much extra space will be needed. This prompt can be thought of as the factory manager asking you to confirm if you are okay with the list of things that need to be bought, and how much space they will these parts occupy once you install a conveyor system in your factory.

Let us first begin with this basic question of why use the command-line interface in the first place! Why not simply download and install an app instead?

Interfaces can be thought of as the middleman between you and the machine , a way to make the machine understand what your wishes are. A TV remote is a good example of an interface, as this device acts as a middleman between you the human and your TV the machine.

Using a remote you can interact with your television, hence your TV remote is an interface! The graphical user interface is the interface we are all familiar with, where we use our mouse or the touch screen to click through various icons and perform the desired action on our computers.

This interface was made to make the operations on computers easier for regular users who might not be as tech-savy as programmers or software engineers. Through CLI, which is a text-only interface, specialists can run their desired programs. The 3 main advantages of CLI are listed below. Now that we have established the fact that the command line interface is very useful, let us learn a few basics of the CLI. A command-line is a line of text which tells our computer to perform a specific action.

As you might already know the words used in the text are specific for a given purpose and not some random text. Unfortunately, our computers have not reached a state where we can just order the computer around the way we see robots are instructed in science fiction movies.

We are getting there with natural language processing AI, but there is an awful lot of processing involved, which is very inefficient. Due to this inefficiency, voice input is never going to replace the good old command-line interface when it comes to cloud computing and data centers.

This is because in data-centers are very power-hungry and better efficiency translates into lower power consumption and lower running costs, which means more profit for the company! Among these 3 parts, the command is mandatory. We have not used any options in this command line. This term is used to get administrative privileges so that we can install and remove software from our computer. Usually, sudo commands are followed by a password request, this is a security measure to prevent malware from getting automatically installed on our computers.

To understand what command and sub-commands mean, you can think of the main command as an app and the subcommand as a button inside that app. So in essence, you are asking your computer to open the apt-get app and push the button named install! You will just have to make sure you have correct headers and gcc compiler for the kernel you're using. Or you just want to try and use the latest driver. It may improve performance or fix an unknown bug or add a feature you've been waiting for.

Note: madwifi does not currently support USB devices with the atheros chipset and the roadmap shows it will be sometime before USB support is built into the driver version 2. You can watch progress at www. This will need to be removed before you can install the latest driver.

All modules in this package will be removed and may affect areas such as your graphics driver. If you need to use a module in this package then you will also have to recompile and install that module also.

There are howtos on the latest nvidia and fglrx in the breezy tips and tricks section of the form. Preparation You will need a working internet connection to complete this howto. Basic knowledge of moving around in the terminal is required. If you are using Breezy, you probably should use gcc 3. A quick way to check the gcc version is gcc --version Before you start the command make, a small edit has to be done to a file so driver will make. Now sudo make There will be some warnings but you can ignore those.

Look for any errors as these will need to be addressed before moving on to next step. You should consider removing them before you continue, or else you might experience problems during operation. Remove old modules? You should remove with option r If all goes well your last few lines should look like this.

In the meantime the ath5k driver has been merged into the linux kernel, and Atheros has come around and hired a linux kernel developer, released a second driver ath9k for newer wireless chips and has taken over maintenance of the ath5k driver. As of the latest distributions Ubuntu 8.

When installing madwifi 0. I finally found the problem described in this email trail which indicates the new ath5k module is the problem.
