Iwconfig wlan0 essid your_essid freq 2432MĬonnecting to open network specifying channel. See iw replaces iwconfig for more examples. The table below gives an overview of comparable commands for iw and wireless_tools. Either use a network manager or use one of the following directly: Managing a wireless connection requires a basic set of tools. Just like other network interfaces, the wireless ones are controlled with ip from the iproute2 package. For these, you can try to use #ndiswrapper. If your wireless card is not listed above, it is likely supported only under Windows (some Broadcom, 3com, etc).

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. Only the usb-id (for USB devices) or pci-id (for PCI devices) is authoritative. Note that some vendors ship products that may contain different chip sets, even if the product identifier is the same. Linux Wireless Support and The Linux Questions' Hardware Compatibility List (HCL) also have a good database of kernel-friendly hardware.

The Ubuntu Wiki has a good list of wireless cards and whether or not they are supported either in the Linux kernel or by a user-space driver (includes driver name).There is also a List of Wi-Fi Device IDs in Linux. See the table of existing Linux wireless drivers and follow to the specific driver's page, which contains a list of supported devices.If the kernel module is successfully loaded and the interface is up, you can skip the next section.Ĭheck the following lists to discover if your card is supported: iwlwifi 0000:02:00.0: Detected Intel(R) Corporation WiFi Link 5100 AGN, REV=0圆B iwlwifi 0000:02:00.0: CONFIG_IWLWIFI_DEBUG disabled # dmesg | grep iwlwifi iwlwifi 0000:02:00.0: irq 44 for MSI/MSI-X

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: # dmesg | grep firmware iwlwifi 0000:02:00.0: loaded firmware version 39.30.4.1 build 35138 op_mode iwldvm

If you get the error message SIOCSIFFLAGS: No such file or directory, it most certainly means that your wireless chipset requires a firmware to function.Ĭheck kernel messages for firmware being loaded:.

If you get errors like RTNETLINK answers: Operation not possible due to RF-kill, make sure that the device is not hard-blocked or soft-blocked.

This is described in #Installing driver/firmware. Many firmware images are provided by the linux-firmware package however, proprietary firmware images are not included and have to be installed separately. Some wireless chipsets also require firmware, in addition to a corresponding driver.

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. The default Arch Linux kernel is modular, meaning many of the drivers for machine hardware reside on the hard drive and are available as modules. 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 #iw section describes how to manually manage your wireless network interface / your wireless LANs using iw. This article covers both parts, and provides additional links to wireless management tools. The second is choosing a method of managing wireless connections.

The main article on network configuration is Network configuration.Ĭonfiguring 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 explicitly), and to configure the interface.
