Bug#659521: [3.1 -> 3.2.4 regression] ath9k: no packets are transmitted or received with WEP
Hello, Jonathan,
sending again with 659521@bugs.debian.org copied in Cc.
in the command log below you see i used 'ifconfig' to assign a static IP and setup a network route,
i also tried to do the same thing with only 'ip' commands, but things worked with kernel 3.1.0-1
and again did not work (as i expected) with kernel 3.2.0-1:
ip link set wlan0 up
ip addr flush dev wlan0
ip addr add 192.168.0.79/32 dev wlan0
ip route add 192.168.0.0/24 dev wlan0
Thank you
Stefan.
I have done the tests as you suggested, the log of all commands for
newer and older kernel is attached hereafter.
Some comments :
- i have no network manager installed (this is one of the first things i get
rid of after installing debian)
- the wifi router has DHCP disabled, and is configured with IP=192.168.0.1 and WEP encryption
- laptop configured with static IP=192.168.0.78
- router responds to ICMP (ping)
Even with the commands you suggested wifi connection does not work (can not ping the router)
with newer kernel and works with older kernel.
I have posted also the wlan0-related lines of dmesg in both cases.
I also have cross-checked the new 3.2.0-1 kernel on another laptop with broadcom BCM4313
wireless chip (brcmsmac module), same debian testing installation and here wifi works perfectly,
so the problem ''seems'' to be related to the ath9k module.
Thank you for your attention
STefan
