I have bought a Model A Pi, and I successfully configured it with a USB Wifi dongle on Raspbian. I recently prepared an SD card with the latest version of Arch Linux ARM and I am trying to get it set up with Wifi. I was trying to follow some other Raspbian tutorials which said that there is a directory /etc/network/ and you could set up Wifi from the interface file, but no directory /etc/network/ exists. I heard about netctl but I have no Idea how to use it! I do have a supported USB Wifi dongle. Could someone please show me how I can setup Wifi on Arch Linux ARM? Thanks!
