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 a Raspbian WiFi tutorial (thinking it could be the same as Arch Linux ARM) 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!
