Many blogs show several Mac individuals with the same problem. I have yet to find APPLE addressing this issue. (not all macs) No Official Apple Support, at all!

Apple Support Community Blog

Over the past year, several Mac users have lost time and money trying to stay connected to the internet with no success. The problem has caused many to spend countless hours trying to connect to internet. Each remedy works for a short time, then disconnects, or a new update comes out, and the wifi wackiness begins again, losing more time, money and sanity.

No word from Apple. Many Apple customers are left in limbo... broke and feeling really frustrated, as we still try to fix this problem through blogs.

**Maybe its time for Apple to identify systems with issues, and offer 50% off next system.... I could of bought 2 computers with the time and money lost on this issue over the last year.
