| Wireless cards based on RaLink's chipsets are very well-suited for Linux computers. RaLink actively supports Linux and the Open Source community by releasing the code for a driver and configuration utility. Based on that code, a re-developed driver for these cards is hosted at [[http://rt2x00.serialmonkey.com]]. This driver (although still in beta) is working good and is quite stable. It is different from other modern wireless drivers in that it has built-in WPA support. It is not dependent on a third-party tool like [[http://hostap.epitest.fi/wpa_supplicant/ | wpa_supplicant]]. The rt2x00 driver will eventually replace the current rt2400, rt2500 and rt2570 drivers. | Wireless cards based on RaLink's chipsets are very well-suited for Linux computers.

| | ==== Kernel-supported rt2x00 (2.6.24 and later) ==== |
| | |
| | The rt2x00 driver included in the Linux kernels since 2.6.24 and which replaces all of the legacy RaLink drivers, does not have a built-in WPA support. Instead, it communicates with wpa_supplicant through the **''wext''** driver of wpa_supplicant. For more information on how to configure wpa_supplicant see the [[:slackware:network#wpa_encryption|WPA section of my //Slackware network configuration// page]]. |
| | |
| | ==== Legacy drivers ==== |
| | |
| | I still use the "legacy" drivers from the Serialmonkey web site myself, since I do not consider the kernel's own rt2x00 driver stable enough (for me the rt2x00 often does not work with WPA connections). Therefore, the rest of this article concerns itself with building and configuring these out-of-kernel modules. |

| I maintain a Slackware package for the rt2500 driver (54Mbit wireless cards) [[http://www.slackware.com/~alien/slackbuilds/rt2500/ | here]]. Install a package for your release of Slackware (the version number should correspond with your running kernel) or build your own package using the [[http://www.slackware.com/~alien/slackbuilds/rt2500/build/rt2500.SlackBuild | SlackBuild script]] and the other files found in that location. An easy way to download all source files in one command is <code> | I maintain a Slackware package for several RaLink drivers.
