I've noticed since I upgraded to 10.9.2 on my 2011 MBP, whenever I wake my laptop up from sleep (open the lid and type my password), the WiFi icon on my menu bar is greyed out, and it takes about 10-30 seconds to reconnect to my WiFi network. During that time, the 'rainbow' icon indicates that it's connecting. This is very annoying, because on 10.9.1 and below, my laptop would be on WiFi and connected instantly upon waking my laptop up. I've repaired permissions and ran Onyx, to no avail. Is anyone else experiencing this problem?
