Cannot install drivers through CDs Ubuntu

Hi forum! I wish to use WiFi for the shared network but cannot install drivers through CDs I have since they are for Windows. I have Ubuntu 9.04 motherboard Asus P5K-E WIFI-AP Solo and Ethernet controller: Marvell Technology Group Ltd. 88E8056 PCI-E Gigabit. If someone can pinpoint which WiFi drivers are available for download and install, that would be wonderful (and guide how to do it as well!).
