I just got new dell inspiron3537 with Ubuntu 12.04 LTS (no windows O/S). It got some wireless (hard block) yesterday. So, this morning, I ran the software update all the security update.

After that I can't see "Wireless" in system setting. So, I updated all the software update and looked thru several web site and found "sudo lshw -c network" command. I tried and found the result below.
