I have a new MacBook Pro with Retinal display. I am not able to connect my Dell monitor through DVI->Thunderbolt. When I do, the external display will not keep wifi. I had no issues with my old MacBook Pro. I know it is not the wifi, as my iPhone has no issue, nor do my other computers connecting to wifi. Thus, I have to either use my monitor or wifi, I cannot use both at the same time.



When I took my retina display Mac to the Genius Bar, they deleted a file that allowed me to connect my monitor while maintaining wifi. This solved the issue. However, when I restarted my Mac, I was not able to maintain wifi while connecting my monitor. Is this the solution for allowing me to use my external monitor and wifi at the same time? If so, where can I find this file for me to remove it in the future?

MacBook Pro (Retina, Mid 2012), Mac OS X (10.7.4)
