Setting this up

• You will need at least two ethernet cables with the rectangular plugs on each end.
  The cable connecting to the wifi access point in the lower stairwell can be repurposed.
  There may be a cable in the plastic box in the guest bedroom, but please leave a large-print note saying when you took it out and where it ended up.
  Let me know, and I can smail more ethernet cables (including shorter ones, which are tidier).

• Plug in one unit in the basement and connect it with an ethernet cable directly to the Verizon(?) cable modem with wifi.
• Plug in one unit in Susan's upstairs office.

• Plug these units directly into the wall sockets, NOT a power strip (which can plug into the power socket on this device).
  I purchased the slightly more expensive version so you won't lose a wall socket.
  Do not plug a high power heater or hotplate or hairdryer into this unit.
  A curling iron, computer, printer, power hand tool, or other medium power appliance should be fine.

• Remove the wifi access point from the stairwell and bring it upstairs to plug into the upstairs unit with an ethernet cable.

• If this works, consider buying two more with wifi. One can plug in at Susan's living room desk, the other in the guest bedroom. Wifi setup might be complicated and confusing.

• The load center (circuit breaker box) downstairs has two 120 volt legs on the left and right. Some of the wall sockets will be connected to one leg, some to the other leg, so there is no direct wire path between some pairs of sockets. While that could be a problem, this Amazon Q&A suggests that the signal can magically bridge the gap between legs. I'm counting on that.
