I followed the steps suggested in the following solution: Qualcomm Atheros Device [168c:0042] (rev 30) Wi-Fi driver installation
But the terminal shows the following:/--------------
| Your kernel headers are incomplete/not installed.
| Please install kernel headers, including a .config
| file or use the KLIB/KLIB_BUILD make variables to
| set the kernel to build against, e.g.
| make KLIB=/lib/modules/3.1.7/
| to compile/install for the installed kernel 3.1.7
| (that isn't currently running.)
What should I do. PS: I'm a newbie in linux. So kindly keep it as simple as possible.
