MacBook Pro Retina 2013 Wifi Problem
My mbp retina is having wifi issues. It says there is no ip address and has an exclamation mark over the wifi signal symbol. I know it is not my router because everything else is working fine. I have tried adding a new location, clearing out system config, restarting the SMC and many other things. This problem occurred a while ago but it came and go. However right now, I cannot connect to the wifi but sometimes I will be able to randomly connect. If I were to sleep or restart the laptop, the wifi will not connect and its back to square one.
MacBook Pro with Retina display, OS X Mavericks (10.9.4)
