I read that from distro 2.6.18 the Linux kernel supported the zd1211 chipset, common for most USB WLAN devices...
I got the 2.6.23 distro from www.kernel.org
patched it with ARM related issues form www.maxim.za.org
run make at91rm9200ek_defconfig
run make xconfig.....
but the only support I see is for zd1201 chipsets...

How to get to get the zd1211 support ?

Thank you in advance for your attention.

take a look at drivers/net/wireless
or in your .config
to CONFIG_ZD1211RW

Grazie.
