are these real device or dummy modem device?

Hello, I'm completely new to this and I'm trying to find identifiable evidence of hacker on my network.

Does this show a TV connection to my modem?

Does this show a user name log in for community.netgear.com?

Thanks for the help, any advice or resource would be appreciated.
