WIFI Connection break up and reconnect irregularly

hi guys,

At First: There are so many threads with topic wifi connection problems, but I'm not sure, whether there is one of the thousands of them with the same topic like mine.

I've bought my MacBook Pro Late 2014 with 256 GB last November.

I've run the update to OS X Yosemite. In the "early" days there were some bug fixes for the wifi controller.

Now after month without any bigger update i've recognized a further problem.

When you close you MBP and open it again after some minutes the network card is able to find my network with a strong wifi connection.

But it is strange, that after some more minutes the connection breaks up und reconnect. This goes on for nearly 10 or more minutes.

The MBP loses the connection and reconnect.

I will lose some nerves if this will last for longer time.

It is something still existing to fix this problem?

Or will Apple roll out some more updates with aiming on the network card?

Thank you !
