I want to use the device as a mobile hotspot initially, but that only works where 3G / 4G is available, but not with slower data transmission. This little thing done now as a universal wireless amplifiers his service (universal repeater) and ensures rich wide extension of a Fritz box and the amazingly well done. Compact and easy to set up if you have Wi-Fi Basic. The printed manual is in microtext for the 50+ generation only with a huge magnifying glass decipherable. Does not matter, because you can Programme the device through the IP address in the browser reasonably intuitive.
