I have used Mythbuntu, Ubuntu 12.10 32-bit OS, and they have all worked properly with the wifi driver which is apparently the Broadcom 4312. Then I deleted the Linux partitions, rebooted with Ubuntu 12.10 64-bit because that was the only 64-bit version I could find. I did it through USB boot, installed alongside my Windows 7.
I noticed before installing that it couldn't detect wifi connections so I used ethernet. It installed as quickly as the 32-bit version of 12.10. I finally got to the desktop environment after rebooting, and I noticed that I still couldn't connect to my wireless internet. I've browsed for hours and hours to get it working, but I still have found no answer. I hope someone can help give me a working yet simple solution. If not then I guess lay it down on me the hard way.
