I followed the post-
No wireless for Intel Corporation 7260 version 63
but when I run the following command-
make defconfig-iwlwifi
(executes fine)
make
I get the an error saying "*** No rule to make target 'card'."
I executed the steps specified on the post on kernel version 3.2.0.29 perfectly, and it worked like a beauty, But once I updated the kernel version to 3.2.0.57 the wifi wasn't available, so I went back to recompile "backport" again as suggested. But this time I got the above error.
