I have Intel Centrino N 2230 WiFi card and I tried to download iwlwifi tar from Ubuntu wireless drivers and then I copied its .ucode to firmware folder and then I ran modprobe -r lawgn andmodprobe lawgn. It didn't run, even after restart. Then I updated the compat-drivers but still didn't work.
I tried rfkill unblock all, checked the button, etc. but it didn't show up in airmon-ng andiwconfig.
Can anyone kindly help because i have been searching and asking for this to many ubuntu users and experts but no one has made me successful instead they went away quietly. So please solve my problem!
This is the output of mine:
