I suppose some people don't use cordless phones at home, or mobile phones, or microwave ovens, or indeed computers, all of which may cause mutual interference.

I don't like wireless repeaters much either.
powerline units only work with both units plugged into the same circuit.
When the wifi was weak upstairs that wasn't an option as the upstairs and downstairs have separate ring circuits as does the kitchen. I can't see a use for them unless a huge house had just one ring circuit.
