I bought this product for a specific functionality, repeater mode, simplistic way to configure, a long press on the single button on the device to blink. In this mode, it behaves like a wireless relay for a specific SSID. As a result, this corresponds to two physical MAC addresses corresponding to the same SSID. Both routing equipment, the repeater and your wifi router, communicating MAC address agree perfectly.
However, some client drivers depending on the OS used and the wifi adapter used to support the SSID and untimely reassessing in use MAC address chosen. And there is the drama! Despite strong signals, routing hardware gatouillent copiously and even for positions conform systematically couples using the same SSID / MAC. Fortunately, 5 in 3 different mobile manufacturers, only one problem. Do not panic, do not throw your machine, take a cheap wifi key, disable the integrated wireless equipment and shoo whether you have chosen your key, your wireless restarts after resetting the repeater.
