If you experience connection dropouts at home\u2014especially in rooms far from your router\u2014you\u2019ve probably wondered whether a PLC or a WiFi repeater<\/strong> is the better option. You\u2019re not alone. It\u2019s a very common question, particularly in larger homes, flats with thick walls or second properties. Let\u2019s break it down clearly so you can make the right choice.<\/p>\n

What is a PLC and how does it work?<\/h2>\n

A PLC (Power Line Communication) uses your home\u2019s electrical wiring to carry your internet connection from one point to another.<\/strong><\/p>\n

It works with two devices: one connects to your router via Ethernet and plugs into a power socket, the other is placed in the room where you need better coverage, also plugged into a socket<\/p>\n

This allows you to extend your connection more reliably than WiFi, as it doesn\u2019t depend on walls or distance. It\u2019s especially useful if your router is in the living room and you need a strong connection in a home office at the other end of the property.<\/p>\n

Advantages and disadvantages of a PLC<\/h2>\n

The main advantage of a PLC is stability<\/strong>. Because it uses electrical wiring, it usually delivers more consistent performance than a WiFi signal that has to pass through walls. It\u2019s also easy to install. You just need two plug sockets and a simple setup following the manufacturer\u2019s instructions.<\/p>\n

However, it\u2019s not perfect. If your electrical installation is old or has multiple circuits, performance may drop. Also, some PLC devices only provide wired connections, without WiFi in the second unit.\u00a0This can limit usage to devices like desktop computers or consoles.<\/p>\n

Differences between a PLC and a WiFi repeater<\/h2>\n

A WiFi repeater<\/strong> does exactly what its name suggests: it picks up your router\u2019s signal and boosts it<\/a>. It connects wirelessly and is placed somewhere between the router and the area with poor coverage.<\/p>\n

Its main advantage is simplicity. No cables, no technical setup. But there are trade-offs:<\/p>\n
