Wireless tools for Linux is a collection of user-space utilities written for Linux kernel -based operating systems to support and facilitate the configuration of device drivers of wireless network interface controllers and some related aspects of networking using the Linux Wireless Extension.

It is included with most operating system distributions built on the Linux kernel. In many Linux distributions, this package is included by default, or based on whether a wireless card is present. If it is not automatically installed by the distribution, it is usually easy to find in binary form. Due to the relative complexity of requiring several separate commands for one task e. The Linux kernel authors consider wireless tools package deprecated; [3] the alternative being the more recent iw utility.

By default, interface names are dynamic, and each network adapter is assigned the first available name eth0, eth Now ifrename allows the user to decide what name a network interface will have. It can use a variety of selectors to match interface names to the network interfaces on the system, the most common selector is the interface MAC address.

Each line displays the specific wireless event which describes what has happened on the specified wireless interface. It doesn't take any arguments. The information reported is the same as the one shown by iwconfig, but iwgetid is easier to integrate in various scripts. The main argument is used to select a category of information, iwlist displays in detailed form all information related to this category, including information already shown by iwconfig.

This scan yields only one nearby wireless access point. It is used to manipulate parameters and setting of the Wireless Extension specific to each driver as opposed to iwconfig which deals with generic ones. Without any argument, iwpriv lists the available private commands available on each interface, and the parameters that they require.

Using this information, the user may apply those interface specific commands on the specified interface. This information is updated each time a new packet is received, so each address of the list adds some overhead in the driver. Note that this functionality works only for nodes part of the current wireless cell, you can not monitor access points you are not associated with you can use Scanning for that and nodes in other cells.

In Managed mode, in most case packets are relayed by the access point, in this case you will get the signal strength of the access point. For those reasons this functionality is mostly useful in ad hoc and master mode.

When I type iwconfig in the terminal, it shows me two wireless interfaces, wlan0 and wlan1.

When I use your library, it only shows one interface. Digging into your code I could find the problem. The problem is in iwconfig. I corrected the problem adding a. The text was updated successfully, but these errors were encountered:. Skip to content.

Note: You must be root for all the configurations, also you can use sudo. Run the command to search the available WiFi networks. Now move down to look for your WiFi network. Note: Where an interface is the network interface that you found using the above iwconfig command.

Run the command —. This command is to check if kernel loaded the driver for wireless card. The output must look like this:. A profile can be created by the hard way or the easy way. In comparison to the above wifi-menu method, this method is a little hard.

In the above command, the network profile was setup automatically. In this subdirectory, you can see different profile examples.

Edit the following fields of your profile using vi or nano:. You must see the profile created by wifi-menu, for example, wlan0-SSID; or if you used the hard way then you must see the profile created by yourself. This will create and enable a systemd service that will start when the computer boots.

So there you go! I have mentioned 3 ways to connect to a WiFi network in your Arch Linux. If you have any problem, then do talk to me in the comment section below. Thank you! Hi, Many thanks for the info.

Configuring wireless is a two-part process; the first part is to identify and ensure the correct driver for your wireless device is installed they are available on the installation media, but often have to be installed explicitlyand to configure the interface.

The second is choosing a method of managing wireless connections. This article covers both parts, and provides additional links to wireless management tools. The Network configuration Network managers section describes several programs that can be used to automatically manage your wireless interface, some of which include a GUI and all of which include support for network profiles useful when frequently switching wireless networks, like with laptops.

The default Arch Linux kernel is modularmeaning many of the drivers for machine hardware reside on the hard drive and are available as modules. At boot, udev takes an inventory of your hardware and loads appropriate modules drivers for your corresponding hardware, which will in turn allow creation of a network interface. Some wireless chipsets also require firmware, in addition to a corresponding driver. Many firmware images are provided by the linux-firmware package, however, proprietary firmware images are not included and have to be installed separately.

To check if the driver for your card has been loaded, check the output of the lspci -k or lsusb -v command, depending on if the card is connected by PCI e or USB.

You should see that some kernel driver is in use, for example:. Also check the output of the ip link command to see if a wireless interface was created; usually the naming of the wireless network interfaces starts with the letter "w", e.

Then bring the interface up with:. For example, assuming the interface is wlan0this is ip link set wlan0 up. If there is no relevant output, check the messages for the full output for the module you identified earlier iwlwifi in this example to identify the relevant message or further issues:.

If the kernel module is successfully loaded and the interface is up, you can skip the next section. Note that some vendors ship products that may contain different chip sets, even if the product identifier is the same. If your wireless card is listed above, follow the Troubleshooting drivers and firmware subsection of this page, which contains information about installing drivers and firmware of some specific wireless cards.

Then check the driver status again. If your wireless card is not listed above, it is likely supported only under Windows some Broadcom, 3com, etc. For these, you can try to use ndiswrapper. Just like other network interfaces, the wireless ones are controlled with ip from the iproute2 package.

Managing a wireless connection requires a basic set of tools. Either use a network manager or use one of the following directly:. See iw replaces iwconfig for more examples. Replace both accordingly.It only takes a minute to sign up. To install:. My first guess after "bad cable" would be that dhcpcd isn't working correctly.

If those don't work, try checking the drivers of your wireless card to make sure you have them. But I didn't need to install 'iw', I think that was installed by the base package.
