Powerline 1000 interfering with existing cable modem

I have used Powerline adapters in other peoples homes and they have worked fine.  I hooked it up in my own house and my cable router stops sending out its Wifi signal.  I hooked into ports 3 and 4 of my Optimum router (not the main port) and directly into an outlet for the "transmitter."  The "receiver" I hooked directly into another outlet.  (I know they are not referred to as transmitters and receivers, but in essence, that is what they are doing).  I am trying to get a Sonos player hardwired on the other side of my home instead of wifi and it should be an easy resolution, and though I got it to work for a few minutes, my main wifi keeps going wacky whenever the Powerline adapters are plugged in and connected.  As soon as I unplug them, everything works fine again... what am I missing?   I am about to return them.

    Not sure what you mean by you hooked into ports 3 & 4 of your router. You should only need to hook up one port to the router side of the powerline device.

      I mean I tried port 3 at one time and port 4 at another time, not simultaneously (I didn't want someone to think I hooked it into the main wireless router port).  The other adapter was at the other side of the house.  Regardless, the anomoly came when the units are plugged into the electrical.

        You don't put what model router it is. Does it have an integrated powerline device into it? 

        If you hook these devices up seperate from the router or at a different location, do they work as they should?
