Hi guys, I'm running a 2011 base model 13 inch MBP. My wifi connection has recently completely died on me. I deleted all of my certificates last night, along with the configuration files in my Library folder. It worked temporarily but is now down again. When I try to connect, I type in my WPA2 code and it attempts to connect to the router, but then comes up with an error saying "connection timeout ". Has anyone got any ideas? Thus is driving me nuts. Thanks.
