Where can I find Linux hardware drivers for my USB wireless network adapter?

Linux driver information for Atmel AT76C503A-based wireless USB devices can be found here. Drivers and installation information for Prism2 devices such as the Linksys WUSB11 adapter is available here.

The www.linux-wlan.org site provides driver software and Linux compatibility information for a number of USB and PC Card wireless network devices.

One of the best places to start searching for drivers for a particular USB device is the Linux Wireless LAN HowTo document. While some of the information may be a bit dated, you can find information on Linux wireless drivers ranging from pre-802.11 standards up through more recent 802.11g and 802.11a devices.

If you still cannot find an open source hardware driver for your USB wireless network device you might look at the DriverLoader offering. DriverLoader delivers a compatibility-wrapper designed to enable the use of standard Windows NDIS drivers on Linux systems.

A free 30-day DriverLoader trial is available for download and the permanent license price is low enough to be quite attractive if DriverLoader works with your current USB device. Installation is straightforward, but you do need a copy of the Windows drivers for your device. To use Wi-Fi Protected Access security with DriverLoader, you need to download and install a second package named wpa_supplicant from the Linuxant download site.
