This case responds rather well to the principal use: extending a WiFi network The first use goes well.. It is therefore a useful product for those who have a Wi-Fi network extended enough. It is then that it becomes more complicated. The documentation contains almost nothing (the Amazon page is much more verbose): not obvious to connect the interface to change the configuration for example. Surprising: no indication on the use of the Ethernet jack. And for the secondary function (listen to music via the jack) connection is often difficult and frequent disconnections. The record is not very positive. It is likely that two good cases with these two separate functions will be more satisfactory.
