Public bug reported:
Binary package hint: linux-restricted-modules-2.6-386
Since the security update to kernel 2.6.17-10-386 (linux-
image-2.6.17-10-386 2.6.17.1-10.34) if have problems with my wlan. The
wireless network device isn't present anymore.
I use a Atheros AR5212 in a IBM Thinkpad T43.
Since the kernel update sudo ifup ath0 reports the following:
Error for wireless request "Set Encode" (8B2A) :
SET failed on device ath0 ; No such device.
Error for wireless request "Set ESSID" (8B1A) :
SET failed on device ath0 ; No such device.
SIOCSIFADDR: No such device
ath0: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device
ath0: ERROR while getting interface flags: No such device
Failed to bring up ath0.
But lshw still says:
*-network UNCLAIMED
description: Ethernet controller
product: AR5212 802.11abg NIC
vendor: Atheros Communications, Inc.
physical id: 2
bus info: [EMAIL PROTECTED]:02.0
version: 01
width: 32 bits
clock: 33MHz
capabilities: bus_master cap_list
resources: iomemory:a8400000-a840ffff irq:11
And lspci says:
04:02.0 Ethernet controller: Atheros Communications, Inc. AR5212 802.11abg NIC
(rev 01)
If I use the old kernel 2.6.15-27-386 everything is fine again.
I noticed that with the new kernel an older version of the madwifi
driver [wlan: 0.8.4.2 (0.9.2)] is used. In the 2.6.15 kernel wlan:
0.8.6.0 (EXPERIMENTAL) is used.
The result is, that dmesg reports the following on boot:
