Update :-<br>
<br>
Re-installed ubuntu onto the Z570 after trying various ubuntu fixes,
install of fedora and opensuse (all fail with various problems,
including only seeing half the ram and wireless fail).<br>
<br>
Now back on 11.10 but with no wireless at all. Here are some outputs
which may be of interest:-<br>

I have tried to re-install all the drivers from the package manager,
but nothing is showing up, even after a reboot. No wireless drivers
are working.<br>
<br>
What I did, after the install, was to disable the acer-wmi<br>
<br>
<code>sudo rmmod -f acer_wmi<br>
<br>
then blacklisted it:-<br>
<br>

Last time I did this, the wireless burst into life, but would not
connect i.e. it would see wireless points and give various
information about them. This time I seem to have totally destroyed
it!<br>
<br>
As I say, I have already tried to re-install all from package
manager.<br>

I have a huge list of instructions from broadcom, which surely
must not be necessary:-<br>
<br>
<a class="moz-txt-link-freetext" href="http://www.broadcom.com/support/802.11/linux_sta.php">http://www.broadcom.com/support/802.11/linux_sta.php</a><br>
<br>
Should I try this? Any opinions or is there a simpler solution? I
know part of this is my fault, but typing instructions in blind
clearly isn't working :)<br>
<br>
I am away for next few days, so am now going to mull it over
before getting drastic again. At least it works wired to the desk!<br>

Suggestions appreciated - thanks<br>

Hmmm, feel free to bring it along to the next meeting, but in the
mean-time, can you post the output of "lspci" to the list?
The last time I had broken wireless was on my Dell netbook. I solved it
by just buying a different mini-PCI card off ebay for about £10 instead
of faffing about. Totally worth it :-)
