Hi,
I currently at home have two desktop computers and two laptops all connected to the same network, which all are shown in the networksafety-map (directy translated from norwegian, mabye another name for it in english) of Norotn Internet Security.
Recently there has shown up another unidentified device on the map, which is connected for only short periods of time. This only happens when I am connected to the the network with one of the laptops (Always the same one). Around the time this started to occur, I purchased a game via Steam store and also started to to play this game via Steam on the before mentioned laptop. Could Steam somehow be the reason for this, for example when you are a host of a game? I am pretty sure it is not someone else who has gained acces to the network as I have changed the network-name and code two times already, and this additional unidetified device only connects for short periods of time when this one laptotp is connected to the network (this also happens when I am not playing online).
Thank you for your help!
