The modem is generally good. For me, the main thing was the presence of two antenna inputs. In my country house, even on the phone, you can’t talk in every place, and you can’t even think about the Internet without high-gain antennas. I put a satellite dish on the roof, bought a 3g - 4g irradiator (in total, for less than 4000) and now I have 4g Internet at a speed of 15 - 20 Mbps . I coped with the flashed modem firmware using the "needle method" plus clearing the "bad blocks" of the memory. All repairs are described in detail on the w3bsit3-dns. Com forum. For those who do not understand firmware, it is better to immediately run to the service center if a situation like mine arises. But judging by the forums, the percentage of firmware crashes in these modems is quite small. So, you can safely buy this Huawei B310. By the way, the B310S-22 currently on sale is no different from the B310. I just bought the B310S-22 in Amazon, it turned out to be 500 cheaper.
