"How does a Wi-Fi range extender socket work?

By positioning the Wi-Fi socket halfway between your router and the area of
poor reception, the range extender will relay the signal to further spread
coverage."

which implies it's a wifi repeater, not a powerline device

OK, but seems a very poor way to attempt to extend wifi, by wifi -
using potentially poorly located sockets low down on walls.

They would be halfway sensible if they used mains signalling to link
the sockets.
