Router eats upload

So I have a wifi conn. At most of the times it's okay, but sometimes I get 50% packet loss and my ping is 15x higher than usual. When I asked my provider, they said that when I connect the antenna to PC or router, it seems like there's a huge upload happening (I'm uploading nothing of course) and they can't even ping the antenna. When I disconnect the cable, they can ping it again.

Any ideas? Sorry if wrong section or so...
