A WiFi solution with 2 powerline adapters provides WiFi in 1 extra place in your house. This way, you can also go online in that corner where you don't have good WiFi right now. To work from home in the utility room or to stream in your bedroom, for example. A powerline adapter sends the internet signal through your power cables. As a result, you don't have to install network cables for stable internet. You can simply plug 1 adapter into the socket at your router and the second one where you want WiFi.
