Is this your thread on the ubuntu forums?
[how to enable wireless?]

This problem sounds very much like the dell rfkill problem reported here:
[Wireless RFKILL defaults to on (wireless off) and can't be turned off]

First off, can you check to ensure that Fn+F6 is working?

$ xev
now Fn+F6
the output show show a status change & output.

If those are indeed working (and most likely are) can you post the
wireless section of:

$ sudo lspci -v
and the output of:
$ cat /sys/class//rfkill/rfkill0/state
and then Fn+F6 and do the command again? A working button (on my system
toggles the state between 1 (wifi on) and 2 (wifi off). Note, you may
have to use rfkill1 instead of rfkill0 - mine uses rfkill0.
