Connection to the "old" PC

Hello There! When selecting the WPS button was important to me. The PC with Windows 7 on board I had connected to a 10m cable to the router.
The N600 Dual Band plug in the UBS port, "read" the software without the user manual recorded at Fritz Powerline 540E pressed the button and the button is pressed briefly on the dual band plug, ready. Later, I entered on the PC in addition to WAP2 key of the router and press the button again and the internet works well. The PowerLine plugs I need for the Ultrabook and the Internet Radio but the old PC with Windows 7, I can not carry it away and because the router is sufficient enough.
The dual band plug works perfectly and I am pleased. Thanks
