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 explicitly), and 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.

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. This is described in #Installing driver/firmware.
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.
The regulatory domain, or "regdomain", is used to reconfigure wireless drivers to make sure that wireless hardware usage complies with local laws set by the FCC, ETSI and other organizations. Regdomains use ISO 3166-1 alpha-2 country codes. For example, the regdomain of the United States would be "US", China would be "CN", etc.
To configure the regdomain, install wireless-regdb and reboot (to reload the cfg80211 module and all related drivers). Check the boot log to make sure that the database is loaded and key verified by cfg80211:
iwlwifi is the wireless driver for Intel's current wireless chips, such as 5100AGN, 5300AGN, and 5350AGN. See the full list of supported devices. The firmware is included in the linux-firmware package. The linux-firmware-iwlwifi-gitAUR may contain some updates sooner. 2ff7e9595c
