I don't mean what you use to chop down your feces, but an object that you realized only your family has and people would raise their eyebrows at. Best if said object has a sole purpose.
Getting reliable internet through the house while renting crappy houses means I end up using ethernet over power bricks.
Every couple of months they will fail and need to be power cycled but the switches on the power point are occluded by the EoP brick without enough room for my fat fingers.
I would just grab any pen or pencil to use as my switch flicking tool but they are constantly purloined by my children so I keep a special internet pencil on my desk.
As long as your house has decent rg6 coax, I had a place with rg59 and those moca adapters worked like shit. Also make sure that filter is in the right place!
