Airportd keeps crashing

I'm running a Macbook Pro retina 13 inches early 2015 with 16 Go of RAM and a 3,1 GHz intel core i7 on OS X El Captain 10.11.1

I keep having some problems with airportd that crashes really often. Sometimes, when I click on the wifi icon on the menu bar, I have the rainbow crash cursor showing up and the menu is not popping up. Then, my mac starts heating up a lot and slowing down and I can hear a loud fan noise. When I check on the activity monitor, the airportd process is taking a huge amount a RAM and 100 % of the processor (sometimes more !). Actually, blued is also taking almost 50 % of the processor…
I have to kill it manually with the activity monitor for it to get back to normal. But the problem is that happens every 20 minutes in average.
I don't know what to do, this is really annoying, I beg for your help !

I keep having this in my system.log :

Dec 13 15:30:21 3wxmr8aqljon9umcd airportd[79737]: SecTaskLoadEntitlements failed error=22

I have that after I kill airportd after a crash:
