Flawless pcl solutionArvosana 5/5
This kit is plug and play and allows to transmit your internet over your electrical wires.
This is usefully if your device is far from your Wireless router and/or has too many obstacles (walls) impacting too much your performance.
My son can now play with his console from his bedroom.
Of course using some long enough Ethernet cable is a superior solution but rather unappealing (your electrical wires are inside your walls), or mesh network (not as cheap) depending on your layout.
