Wireless stops passing traffic
I'm having wireless networking problems with my 27-inch, Mid 2011 running 10.8 (Mountain Lion). Everything was working perfectly until last week, shortly after I issued this command: /System/Library/PrivateFrameworks/Apple80211.framework/Resources/airport -A'LAGnet' BSSID='f8:1e:df:fd:34:9e' password='password' I'm not sure if this command caused the problem, or it was just a coincidence that the problem started after I ran it.
The wireless stays connected, but stops passing traffic. This happens randomly, and sometimes so often it's hard to even use the computer.
You can see a demonstration of the problem here: http://www.youtube.com/watch?v=foemRKWGmT4
This problem JUST started happening last week. No new software was installed, and everything had been working fine before.
I opened a trouble ticket with Apple. They came back and said the problem was being caused by 3rd party software, and gave me a list of apps that they thought may be causing it. I removed all of the possible apps and still had the problem.
So I zapped the PRAM and WIPED the hard drive, and installed 10.9 (Mavericks), where I still had the same problem after a clean install, without migrating any of my old profile.

My gut tells me this is a NVRAM/firmware issue. But I suppose it could also be a hardware failure issue...
Has anyone run into this problem before or have any idea how to solve it?
