I running tests in a family members basement. On day six. After looking at the data it works all day and will work with a 20 dollar wireless router. The one I have has 3, 5 dbi antennas, and then I use another cooler looking wireless router as the one that provides wireless internet but a direct line from the lab port to provide a Ethernet connection. It’s a older house, from what I hear before 1986, but ya it can work and work very well. Power lines are expensive and you can have some nasty hiccups from other stuff that’s needs electricity. It’s up to you want to do and what you need the internet for. But it can work for gaming, and that works then a lot of other forms of internet use shouldn’t be trouble, and the floor is a high quality type of wood above me, and the main cable modem/router is on the floor.
