I bought a router to get more LTE speed and more functionality. I use a router in a country house, the operator's tower Megafon-Moscow (Russia) is in line of sight 1 km away from me. I used to use a huawei 525 router, it worked in b7 + b7 and gave out dl 100-200 and ul 30-50 megabits and ping 85-95 (a similar xiaomi mobile phone) By connecting a new Mikrotik Chateau 12 router, with firmware v7.1beta2 (firmware modem EG12EAPAR01A06M4G) I saw the best reception speeds in the same b7 + b7 aggregation, in most cases the best ping is 50-60ms, and higher uplink (ul 40-65), but the download speed has become at the level of dl 10-30 megabits. Initially, the firmware was stable 7.0, but this did not affect the speed in any way. In addition, I know another person who, in another city, also at the dacha, also bought Chateau 12 instead of huawei 525, and got about the same speeds as mine - 30 versus 200 megabits (operator Megafon Moscow, but a different area) ... I took all measurements in one place, with the same SIM-card at the same time. What should I do? Return under warranty, or is it possible to diagnose the problem differently and get rid of it? I am attaching 3 screenshots: mikrotik chateau 12, huawei 525, xiaomi t9 pro.
