    i use my mac mini for work every day, yesterday evening i turn it off and was working
    today is not connect to internet and it says that it can't find any cable connect to ethernet

    i can't even reach my rooter via browser

    if i reboot in rescue mode i try with search help online that opens a safari browser and it words
    is not an hardware issue

    the only special thing about my set up is that i run OS X ( since more that 2 /3 years ) from usb3 SSD

    i have no clue on how find what it made my ethernet stop working

    A few thoughts...

    Does your router have wireless?
    Can you connect via wifi at all?

    If you can't connect via wired or wireless, could it be a router/modem setting?

    I would try powering down everything (all the way off):
    Modem, router, mini, etc.
    Then, reboot everything.
    Any changes?

    I have read that USB3 can put out "interference" that affects bluetooth and wifi on the Mini.
    Does moving your external boot drive around change anything?

    If you believe that you've had some kind of hardware failure with the ethernet, you could try buying a USB/ethernet adapter, and using that instead. They cost about $20 (US) or so...
