I bought it for the dacha, without an antenna the signal was weak, I caught a maximum of 3G. With antenna stable 4G. There are no complaints about the distribution of Wi-Fi at all. As for the settings, this is the case when any housewife can handle it, but the geeks will not like it. In principle, in terms of ease of maintenance, an ordinary household appliance is no more complicated than a refrigerator. Regarding the antenna, the instructions do not recommend connecting outdoor antennas (apparently reinsurance), but it works much better with a directional outdoor antenna. . I figured out the colors of the mobile network indicator: red - no network yellow - 2G blue - 3G green - 4G
