Home Wifi Issue after updating to 10.10.2

Hello Guys,

I have a very STRANGE issue after i had updated to 10.10.2

My macbook does not want to use the internet on my home network, but when i try to connect on any other networks it works perfectly so i though the problem was my home network, but when i tried other devices (my wife macbook, and my mobile phone and even ipad) all of them working perfectly on my home network

so here is the deal,

My macbook wifi works great on any network but my home network

my home network works great on any other device and laptop other than mine

Did anyone here heard about such a thing before??? any recommendations???

for sure i restarted the router million times, reconfigured the network..ect and all other basic stuff...

so please give me something big and creative

My device info. is

OS X Yosemite ver. 10.10.2

Mac Pro Retina, late 2013, 2.4 GHz

Thanks in advance
