3 windows 10 pcs

to my router i have connected a win 10 pc, my tv and then i connected 1 of the tl pa7017 powerline. All the other pcs are connected to their own powerline.

when all are connecteds to in the howse all work fine and the pcs can see and connect to each other.

The problem  i have is that when i move a windows 7 pc to an attached garage the pc will connect to the internet but will not connect to other computers or servers. If i bring this pc with its powerline in the hose all works fine again wint no tweaking
