Ar9485 - SET failed on device wlan0

I am trying out Crux linux and seem to be stuck on enabling my wireless internet.

My card : Atheros AR9485
kernel : 3.6.11

I believe that the module is the ath9k which I have enabled.
ifconfig and iwconfig show the device as wlan0.
However, when I try to set the device via iwconfig, I receive a SET failure.

Code:

iwconfig wlan0 essid any

Cannot read /proc/net/wireless

Error for wireless request "Set ESSID" (8B1A) :

    SET failed on device wlan0 ; Invalid argument.

I've searched online without a clear answer. Any help would be appreciated.

Thank You

Run lsmod and check if the ath9k and ath9k_hw modules are loaded. Run "modinfo ath9k" for more info, such as firmware files if any.

If /proc/net/wireless doesn't exist, you may be missing some even more basic wireless modules. Make sure wireless isn't disabled in bios or a switch.

Code:

modinfo ath9k

It looks like your kernel modules are present. Does /proc/net/wireless exist? If so, did you run iwconfig as root?

No /proc/net/wireless does not exist and yes, I ran iwconfig as root.

It doesn't seem to make sense that the kernel module is loaded but /proc/net/wireless isn't created by the kernel. Look through your boot up logs for clues. Check your kernel config file in /boot/. Is a related networking module not enabled? Do you have a /proc /proc line in fstab?

Yes, there is a proc line in fstab.
/proc/net does exist and is populated with many items, but wirless is NOT one of them

The only entries in boot logs that refer to the wireless are below:

as far as a related networking module not being installed. I have no idea what that would be.
I followed instructions here:
http://linuxwireless.org/en/users/Drivers/ath9k

The mac80211 driver is what I was thinking of. It looks like it is present. What is your kernel version?

Does /proc/net/devices exist? Another post asked if ath9k_pci is enabled in the kernel.

http://forums.gentoo.org/viewtopic-t...2-start-0.html

This thread ona Gentoo forum is maybe similar.
You seem to be missing the same kernel module.

I followed the thread. I do have the ath9k_pci enabled, so that didn't help.

Here is the output of # zgrep _ATH /usr/src/linux-3.6.11/.config

Code:

CONFIG_NET_VENDOR_ATHEROS=y

CONFIG_ATH_COMMON=m

# CONFIG_ATH_DEBUG is not set

# CONFIG_ATH5K is not set

# CONFIG_ATH5K_PCI is not set

CONFIG_ATH9K_HW=m

CONFIG_ATH9K_COMMON=m

CONFIG_ATH9K_BTCOEX_SUPPORT=y

CONFIG_ATH9K=m

CONFIG_ATH9K_PCI=y

# CONFIG_ATH9K_AHB is not set

# CONFIG_ATH9K_DEBUGFS is not set

CONFIG_ATH9K_RATE_CONTROL=y

CONFIG_ATH9K_HTC=m

# CONFIG_ATH9K_HTC_DEBUGFS is not set

# CONFIG_ATH6KL is not set

I'm not sure that I see anything missing?
