The zd1211rw (and zd1211rw-d80211) driver is a community effort to rewrite the wireless driver for Linux that ZyDAS released. This driver is the so-called "rewritten driver", hence the "rw" in the name.
There are some possible instability issues, particularly on ZD1211B chips.
The zd1211rw driver supports the AL2230, RF2959 and AL7230B RF chips with ZD1211 chips and the AL2230 RF chip with ZD1211B chips.
The current hardware list is maintained at http://zd1211.ath.cx/wiki/WikiStart#Hardwaresupported
Note that the list also contains devices that are "Untested with rewrite", i.e. not tested with this driver!
- Station mode
- A/B/G support (but only few devices support A)
not working yet
- hardware crypto assist
- ad-Hoc mode
- AP mode
The firmware needs to be downloaded from http://sourceforge.net/project/showfiles.php?group_id=129083 and extracted/installed so that hotplug can find it (the exact directory depends on your distribution..
