+      iw is a new nl80211 based CLI configuration utility for wireless devices.
+      It supports all new drivers that have been added to the kernel recently.
+      The old tool iwconfig, which uses Wireless Extensions interface, is
+      deprecated and it's strongly recommended to switch to iw and nl80211.
