My new Macbook Pro (13", i7, Early2015, OSX 10.11.4) is loosing its Internet connection every couple minutes. The WiFi itself stays logged in, but the internet connection is gone. After a short while it sometimes comes back. Usually I deactivate and activate the WiFi to make it work again. The problem occurs in every WiFi I log into.
I checked the Console and the following error is showing always when the Internet is gone:
send_datagram_available_ping: pid 468 failed to act on a ping it dequeued before timing out.
I already tried to deactivate the "automatic brightness control" after finding a thread on the Apple dev forum. Did not help.
How can I need to fix this?
