I had no idea of these wifi amplifier. Now I bought this cheap thing and am extremely happy, have Wi-Fi throughout. Manual is in English, but it goes without English levels. Simple device into a wall socket, then turn smartphone WiFi, Wireless N Click, Browser search bar can write 192.168.10.253 and looking, Logo appears: username -admin password - admin language - English, Blue square with router draufklicken, Click on your router, then at your SSID repeater name and password (arbitrary) clicking Save & Reboot. Done. now again looking Fi and your repeater Select password. Take the repeater down in the basement outlet pure and losgehts ;-) much Spassss
