Hi all,
Recently i upgraded my Operating System to Ubuntu 14.04 LTS from ubuntu 12.04 LTS in my Dell Vostro laptop. But after upgrade has finished i found my wifi connection not working in Ubuntu 14.04.
I checked #ifconfig -a, but wlan0 is not listed in the list of interfaces.
After some research i found the solution.
Here i'm providing some commands to troubleshoot your wlan interface.
> Check all the wireless devices available in the system and their state (block or unblock)
