No Wi-Fi whit Linux kernel 3.2 and Ath AR9287


I updated my kernel to 3.2 (with some changes to CPU section), but Wifi doesn't work anymore, even if my wireless card is recognized by
Code:
lspci
And
Code:
ifconfig -a
returns me just the Ethernet.
Suggestion?

What distribution are you running?

If you built 3.2 yourself then it's entirely possible that you didn't build in ath9k support. Rebuild the kernel and ensure that you load the config from your previous kernel as a starting point.

I'm running Debian Squeeze 6.0.3.

I verified the kenrnel config, but the ath9k feature is already loaded as module.
But using
Code:
lsmod
there's nothing about "ath9k".

Double check this for the running kernel:
Code:
grep -i ath9k /boot/config-`uname -r`
What happens when you try to load the module:

Code:
modprobe ath9k

First:
Code:
CONFIG_ATH9K_HW=m
CONFIG_ATH9K_COMMON=m
CONFIG_ATH9K=m
# CONFIG_ATH9K_PCI is not set
# CONFIG_ATH9K_AHB is not set
# CONFIG_ATH9K_DEBUGFS is not set
CONFIG_ATH9K_RATE_CONTROL=y
# CONFIG_ATH9K_HTC is not set
The second command loads me the module, but the output of
Code:
iwconfig
returns me there's no wireless cards.

Very odd... debugging exactly what is going on there may be more trouble than it's worth. Do you need the new kernel to support newer hardware you have? I would guess not, if you really need the latest kernel, you're better off running testing or unstable.

I would suggest you build an earlier kernel and see how that works out. 2.6.39 is in backports - try installing that and see if your wireless nic works, if it does then you can build your kernel against the 2.6.39 source. i.e. "apt-get source" the 2.6.39 kernel to get the debianised source, make your changes and rebuild it - you might get better results.

Yes, I understood your point of view. I came back to use an earlier version.
Thanks
