 ---------------------------------------------------------------------

Installed and checked the following kernels 3.2.0.24, 3.2.0.25, 3.2.0.26

I have not had a lot of time tonight to fully test these kernels but I
gave each about 20 minutes and I'm leaving them installed so I can go
back and forth between kernels until I find the breakpoint.  For some
reason I'm thinking the problems started at 3.2.0.40ish. So tomorrow I
think I will start at like 3.2.0.50ish and work backwards. Each night I
will update this thread with my kernel checks until I find the culprit.


p.s.
@  Larry
I suppose since you're saying that opensuse works great it might be easier to just start using that distro. I see there is support for a lot of desktops, including LXDE and I see it uses RPM. 
Although I would prefer Fedora because I know the documentation there is superb. How is the documentation for opensuse? Do they have downloadable documents equivalent to a large book that covers every single aspect of the inner workings? Or are you stuck with online wiki type pages? I want to be able to download the information and have it offline in book form so I can read it at my leisure. Fedora releases this information for every new version of the OS they release so it's not like its out of date material.

And as far as my comment where I was thinking you said Fedora.... I
don't know where that came from but you can see that I've got Fedora on
the brain. Nothing beats good documentation, it sure makes figuring out
issues a lot faster. Wouldn't it be nice if realtec understood that.

Bug description:
  Wireless no longer seems to work since I upgraded to Precise, it was working (albeit very flaky) ion 11.10, but it never seems to be able to connect to any access points since the upgrade.
  It can see all the available networks, but it can't seem to connect to any of them.
