The Ubuntu Laptop testing team also apparently gave up, but it works now 
and then with the XP driver, not always. Have a look - 
https://wiki.ubuntu.com/LaptopTestingTeam/AcerAspire5570-2792

If you still want to try and set it up with the XP driver that is flaky, 
here's the how to that my friend Aditya wrote for me ..

Step 1: Disable ath_pci

sudo rmmod ath_pci
sudo gedit /etc/modprobe.d/blacklist-common

Add the following line at the end of the file

blacklist ath_pci

Save and close

Restart computer

step 2. remove any old ndiswrapper by using synaptics or apt-get purge 
ndiswrapper


Step 3: Install the latest  Ndiswrapper.


Step 4: Find your Windows Wifi (Atheros) Driver folder

cd /directory of XP driver/

 

Step 5: Load drivers with ndiswrapper.
sudo ndiswrapper -i net5211.inf


< It should say >


installing net5211 ...

........ a lot of lines like above...

then do a:
sudo ndiswrapper -l
net5211 : driver installed
device (168C:001C) present (alternate driver: ath_pci)

Step 6: Load ndiswrapper and check if it worked
sudo modprobe ndiswrapper

Check it with :


dmesg (show that the card installed)
iwlist wlan0 scan (will show all APs arround you)

Then I did:

sudo ndiswrapper -m

sudo reboot

And the wireless should work... now and then!
