My first words where exactly that I have experience with this device as stated. The first unit malfunctioned after 6 months, delivering poor performance the whole time and intermittent signal, 5G signal would go out consistently requiring a restart of the unit. Placement was from one room to the other over standard walls. Repeater was already at 50% speed from main unit, therefore much slower speeds. After the first one died I was supplied a replacement, same unit different manufacturer name, same software as well. The software provided on this is done y manufacturer not the ISP provider, the way I know is that i followed manufacturers configuration booklets online and they were the exact same details. Second unit performed even worse, 5G signal would kick out consistently after a couple of hours and would go into red, then it would forget settings and broadcast original SSID and also the updated SSID, 2G signal was slow and intermittent, sometimes it would work others it would not requiring system to be restarted and another circle of errors to start. I have the unit with me, I Will happily ship it to you free of charge just so it can give you the same headaches it gave me since your trying to be a smart ( ( ).
