The driver needed are ath9k as per my research. but modprobe ath9k is giving following error.

user@user#modprobe ath9k
modprobe: FATAL: Module ath9k not found.

In Actual this files are there inside library module folder

user@user:/lib/modules/3.16.0-4-amd64/kernel/drivers/net/wireless/ath# ls
ar5523  ath10k  ath5k  ath6kl  ath9k  ath.ko  carl9170  wil6210


user@user:/lib/modules/3.16.0-4-amd64/kernel/drivers/net/wireless/ath/ath9k# ls
ath9k_common.ko  ath9k_htc.ko  ath9k_hw.ko  ath9k.ko

I have found my solution ,i had installed two kernels by mistake. 1)Linux 3.16.0-4-amd64 2)Linux 3.18.13-rt10mah+ x86_64

ath9k driver was available in 3.16.0-4 folder but not in 3.18.13's folder Because of that modprobe ath9k didn't worked.

Copying driver files from 3.16.0.4's directory to 3.18.12-r10 also didn't worked.

So i downloaded backported ath9k driver dump from Backported kernal portal To Download all stable releases

and selected version, near to my kernal's version : v3.18-rc1 and foloowed following steps.

  1. download kernal backup

  2. Extracted the backup

  3. navigated to extracted folder location

  4. Commanded following commands (use command Make help to see possible options to install the drivers from package)

    sudo make defconfig-wifi sudo make sudo make install sudo update-initramfs -u reboot

And it solved my initial problem of Network remaining unclaimed. if anyone still facing similar issue: email me on hd.gcet[AT]gmail i'll be happy to help you, because it took 5 days for me to resolve, and documentation on installation this way is available very little, and in bits and pieces.
