I tried installing Ubuntu 14.04 64 and 32 bit versions on my laptop with no luck. I then got an older version of Ubuntu 11.04 and got things up and running. All seemed to work except my wifi. I upgraded to Ubuntu 12.04.4 and same thing.

After install I got white text message during the boot up in the top left hand corner of the screen saying;

( 23.3856131 b43-phy0 ERROR: Firmware file "M3/ucode.fw not found ( 23.3856221 b43-phy0 ERROR: Firmware file "M3-open/ucode5.fw not found ( 23.3856271 b43-phy0 ERROR: You must go to and download the correct firmware for this driver version. Please carefully read all instructions on this website.

I went to that website and there was nothing listed for my Acer Aspire 9300. There were several Acer's listed but not the 9300. How can I get my wireless working?

Please keep in mind I am brand new to Linux and Ubuntu along with everything in it. I have some DOS experience from 20 plus years ago but have been windows based ever since. Ideally I'd like to get this laptop running Ubuntu 14.04 in future. I'm thinking if I can get the wifi working in an older version and then do an upgrade to a newer version that the drivers and or files will be carried over to the new version with the upgrade. Yes no?

So, where do I start? Thank you in advance.
