I can come up with no explanation why it would have been working before.
That kernel doesn't have support for your wireless hardware.
You've got a few options for getting it working. Probably the easiest is
to install the backports drivers. For this you need to install the
linux-backports-modules-cw-3.8-precise-generic package, either using the
software center or by running "sudo apt-get install linux-backports-
modules-cw-3.8-precise-generic" in a terminal. You'll need to reboot
after doing this.
The other options are either to upgrade to a newer release or use our
hardware enablement stack. Let me know if you want instructions for
either of these.
It doesn't seem necessary to add support to Linux 3.2 since we already
have a couple of options for getting your hardware working in 12.04, so
I'm changing the status to Won't Fix.

Title:
No wireless connection after updates 12.04LTS
Status in “linux” package in Ubuntu:
Won't Fix
Bug description:
I am using HP "all in one" with Ubuntu 12.04 LTS installed. Following
the last update, my wireless network connection is lost. I have both
wired and wireless connection if I boot with older version 3.2.032,
but with new version 3.2.055 after update I only have wired
connection, but no wireless connection.

I have 2 versions on my front logon screen.
One is linux 3.2.055 and the other is 3.2.032 The default is 3.2.055
on boot up I can get a wired connection but no wireless connection.
If I boot on 3.2.032 I can get both a wired, and wireless connection.
Many thanks for any help.......(New to Ubuntu)
