What do Homeplugs do?
Homeplugs basically send internet down your mains. They take an ethernet connection (LAN) from the router into the back of one home plug unit, then you plug it into a wall socket. You then plug another homeplug into another wall socket and take an ethernet cable from that into your Computer or TV etc, or if a WiFi homeplug is used then you get an extended wireless connection for your device.
Installation is simple with the HomePlug’s built-in plug-and-play technology.
Can you plug powerline adapter into extension cable?
Powerline Adapters (Homeplugs) will only work properly if you plug them directly into a wall socket: not into extension leads. Only use extension leads as a last resort, if there’s no other option. Most models of Powerline Adapters have a plug socket, which means you won’t lose a mains socket after it’s been plugged in.
