if you want to search for networks & connect to them, you need a network manager. if you are using traditional ifup method to connect, you can run iwlist wlan0 scan in a console. or you could use wifi - radar,found here http://wifi-radar.systemimager.org/ rpm's are dependent on your SuSE version. if you are using Knetwork manager, if your card is configured to work with it, it will automatically show available networks
