Linux has patchy Wi-Fi support.[3] This is especially true for older kernel versions, such as the 2.6 series, which is still widely used by enterprise distributions. Native drivers for many Wi-Fi chipsets are available either commercially or at no cost,[4] although some manufacturers don't produce a Linux driver, only a Windows one. Consequently, many popular chipsets either don't have a native Linux driver at all, or only have a half-finished one.
