Suddenly yesterday my mac started to have WiFi-problems. I have had this mac since 2011 and it has always worked and I have only been using it on WiFi.
But today when I woke it up it didn't enable the WiFi. I tried to disable WiFi and enable it again but it didn't work.
I rebooted. It worked. After ~5 minutes it stopped working again.
Now I'm using my iphone (via USB) to connect to internet. Works fine.
Just before the problem occurred I installed the following updates:
- Remote Desktop Client Update V3.8.4
- Command Line Tools (OS X 10.10) V6.3
Does anyone have any tips for me?
Thanks in advance :)
Update: I add a section from my wifi.log file on the time of one of my failures

Update
Today (4 weeks later) my MBP couldnt enable the wifi when I woke it from sleep. I turned it off via the terminal and then I turned it on with:
networksetup -setairportpower en1 on
My computer froze. The most interesting I could find in the log is
kernel[0]: en1: Error configuring antenna diversity (index = -1).
I have no idea what that means though. Ideas?
I could also find the following in the log
Wifiscript[1018]: dig attempt via

And now after some more reboots it says No hardware installed and I cannot get the card to work at all :(
