Actually, I had a wireless router. So I have less Wellensalat in the house and from the office in the living room and the first floor can use Internet-LAN ports, I've bought a Devolo system. She works prima and can be supplemented as needed with a Devolo Wlan plug, so I use the laptop in the pool swimming House can work (in the courtyard). These products are of high quality, functional and therefore highly recommended!
