Wireless networking in Linux

I was discussing recently with my friend about setting up a wireless network on Linux systems.Although wired networking on Linux flavors is a breeze, wifi networking isnt necessarily like that.

First of all you need to make sure that the Wifi PCI card that you intend to buy must support or have Linux drivers, or else you wont be able to use it at all!

The best place to check that is madwifi, but this is mainly for atheros based chipsets, and not others,usually these will be supported by dd-wrtx86, like the Dlink DWL-G520.

Installing wifi chipset driver also requires some knowledge of linux, usually USB based wifi devices are more difficult to install rather than the normal Wifi PCI adapter.
