for me : lspci | grep -i athe 
06:02.0 Ethernet controller: Atheros Communications Inc. AR2413 802.11bg NIC (rev 01)

and my wireless connection works fine with wlan0 and the kernels:
2.6.30 , 2.6.31, 2.6.32 except with the last kernel 2.6.32 (2.6.32-3)

So I wonder if this is a kernel bug ?

happy new year 2010 to all.
