I had a similar problem with failing WiFi on my mid-2010 MacBook Pro.
When I used a third-party MiniDisplayPort to DVI adapter, wireless would not work. When I used the Apple adapter, it worked fine.
Interestingly enough, I found that under some circumstances the 3rd-party adapter will work fine. My working theory is that it doesn't have as much shielding as the Apple adapter and puts out just enough interference to clobber my WiFi signal when I'm far enough away from the access point.
Maybe this is the same issue?
