Wifi detecting but not working rt3060

view story

http://askubuntu.com – I have just installed Ubuntu 13.04. All my WiFi settings are fine and other devices can connect and use the net. But in my recently installed Ubuntu 13.04, it detects but doesn't connect. PCI card Dlink DWD-525 I tried this method : ( The one with the 100+ credits, No 4 ) How do I get a Ralink RT3060 wireless card working? Now my PC won't even detect WiFi Networks. Please I am a bit new to all this as I have been using Windows my whole life. Any help would be appreciated (HowTos)
