Im running low on wall sockets so will Powerline networking work through electrical extension blocks or a powerstrip?
Powerline Networking will usually operate through a power strip although its speed is reduced a little. Its impossible to state by how much because different types and sizes of power strip produce different effects but weve yet to see one that completely fails to connect. It is not ideal though, and power blocks with built in UPS or line filters will prove particularly problematic and should be avoided.
