[Voyage-linux] Problems with alix 2d3 and madwifi on voyage-current (lenny)

Wed Feb 25 17:18:31 HKT 2009

Same results from me. Only rc2 works reliably.

My configuration is: AP with atheros Wistron CM9,  hostapd setup with
WPA2-PSK with TKIP.
Clients used for testing are two laptops with ralink chipset and two desktop
pcs with atheros (all running microsoft OS). I also have same problems
without the use of hostap (no securitu or wep security). The only thing I
haven't tried yet is using the ath0 interface alone (I am using a bridge
interface with ath0 and eth0 as br0).
