Our ISP asked if I was satisfied with their service. I told them that it's okay, but some of our computers don't have enough powerful network card, and they can't use the internet on maximum speed, and they said that they could see it, too. WTF? I knew that the ISP's router is not the most secure thing, but it has a remote mode, which if of course OFF, and they still can see this, and maybe even more. Monitoring your traffic is a thing, but a home network should be private...
