My macbook pro with retina can’t automatically connect to wifi after the wifi router was rebooted. There is exclamation mark on wifi sign. As I clicked the wifi sign, it shows no Internet connects. However, It is strange there is a tick in front of my wifi name. In order to use wifi, I had to click off wifi, and then click on. The previous version, Macbook pro, has no problem like this. I had deleted all files under wifi library, but still fail. Appreciating for any way to solve it!
MacBook Pro with Retina display, OS X Mountain Lion (10.8.3)
