Update :-

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).

Now back on 11.10 but with no wireless at all. Here are some outputs 
which may be of interest:-

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.

What I did, after the install, was to disable the acer-wmi

|sudo rmmod -f acer_wmi

then blacklisted it:-

|

echo "blacklist acer-wmi">>  /etc/modprobe.d/blacklist.conf


|Here is the blacklist file:-

# This file lists those modules which we don't want to be loaded by
# alias expansion, usually so some other driver will be loaded for the
# device instead.

# evbug is a debug tool that should be loaded explicitly
blacklist evbug

# these drivers are very simple, the HID drivers are usually preferred
blacklist usbmouse
blacklist usbkbd

# replaced by e100
blacklist eepro100

# replaced by tulip
blacklist de4x5

# causes no end of confusion by creating unexpected network interfaces
blacklist eth1394

# snd_intel8x0m can interfere with snd_intel8x0, doesn't seem to support 
much
# hardware on its own (Ubuntu bug #2011, #6810)
blacklist snd_intel8x0m

# Conflicts with dvb driver (which is better for handling this device)
blacklist snd_aw2

# causes failure to suspend on HP compaq nc6000 (Ubuntu: #10306)
blacklist i2c_i801

# replaced by p54pci
blacklist prism54

# replaced by b43 and ssb.
blacklist bcm43xx

# most apps now use garmin usb driver directly (Ubuntu: #114565)
blacklist garmin_gps

# replaced by asus-laptop (Ubuntu: #184721)
blacklist asus_acpi

# low-quality, just noise when being used for sound playback, causes
# hangs at desktop session start (Ubuntu: #246969)
blacklist snd_pcsp

# ugly and loud noise, getting on everyone's nerves; this should be done 
by a
# nice pulseaudio bing (Ubuntu: #77010)
blacklist pcspkr

# EDAC driver for amd76x clashes with the agp driver preventing the aperture
# from being initialised (Ubuntu: #297750). Blacklist so that the driver
# continues to build and is installable for the few cases where its
# really needed.
blacklist amd76x_edac
blacklist acer-wmi


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!

As I say, I have already tried to re-install all from package manager.

I have a huge list of instructions from broadcom, which surely must not 
be necessary:-

http://www.broadcom.com/support/802.11/linux_sta.php

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 :)

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!

Suggestions appreciated - thanks
