wireless interference from other access points + conflict between bcma and b43 wireless drivers -> Wireless Network controller [0280]: Broadcom Corporation BCM4331 802.11a/b/g/n [14e4:4331] (rev 02) not working reliably on Apple iMac13,2 in Ubuntu 12.04.4 LTS 64-bit edition

Hello, I've reviewed previous question 134619 and if it works specifically for me and my computers, I can't "translate" the suggestions there into Mac. I would appreciate some assistance.

I see many people have had problems and I've searched the forum but I don't see a resolution for the iMac. Very new to Ubuntu/Linux. Don't quite understand all that I've done thus far but working on it. This is my 4th install 12.04, 12.04, 13.10, now back to 12.04 - and this is the first time I've even been able to connect to the Internet booting from the harddrive - Yay! - but it won't stay connected for me long enough to *do* anything. Can't upload Chromium, load codecs, etc.

My computer is a iMac 27", Late 2012 2.9 GHz Intel Core i5 8GB, Dual Boot with OS X 10.9.2. I'm trying to connect to ATT952. Ubuntu is on the harddrive (Internet worked fine from LiveCD and works fine in Mac OS)

If I have misunderstood your requests for specific information, please excuse and just tell me how I should find the information you need

Will you ladies and gents help me? Thank you
