Please help me out I am novice in linux. I ran the command to check whether my wireless adapter is working. Below is the result. 

deepu@deepu-Aspire-VN7-592G:~$ sudo lshw -C network

Please try with a temporary internet connection:

sudo apt-get update
sudo apt-get install linux-headers-generic build-essential
wget https://www.kernel.org/pub/linux/kernel/projects/backports/2015/11/20/backports-20151120.tar.gz
tar -zxvf backports-20151120.tar.gz
cd backports-20151120
make defconfig-ath10k
make
sudo make install

Reboot. It will probably be missing the required firmware. Please find out and post:

dmesg | grep ath

I will edit my answer to provide a method to locate and install the firmware.

  • I have a similar problem. Using this answer, I adjusted wireless connection, but is very slow and many packet loss. Here is my output of dmesg | grep ath. – VeLKerr Jan 23 '16 at 16:39
  • @VeLKerr Please start your own new question. – chili555 Jan 23 '16 at 17:19
  • no, I already solved my problem by creating config file: echo 'options ath10k_core skip_otp=y' > /etc/modprobe.d/ath10k.conf. The idea was taken from here, see 10th message. – VeLKerr Jan 23 '16 at 20:05
