I recently acquired a Megafon M150-1 4G modem. The elderly Zyxel Keenetic stayed with him, but he was unstable; for ten days, he strove to provide support for him, changing and reconfiguring him, but none of these things helped. I recently acquired a TP Link 3420. It immediately set up, but then it restarted when I ran the test on Speedtest.net; the customer service did not assist in any way, despite the fact that it responded swiftly. I was exhausted, so I went to the outskirts of the city, bought a microtic, inserted a modem (before to that, I turned it to 4G Modem only mode), and he connected after registering the Beeline APN (the modem is unlocked, and the SIM card is beeline). After that, everybody started dancing. When I was in school, I gained experience in Linux networking. Despite my best efforts, I was unable to configure Internet distribution using the elevated modem interface. I looked it up on Google just in case the most recent firmware had a different version. Things worked out very easily in the end. You will need to enable masquerading through the modem interface by going into the settings for the IP firewall and the NAT. ALL. It functions consistently, has long uptimes, and the speed does not fluctuate (TP Link cut before hanging). I went on to configure the NTP Client so that the time would be accurate (yes, nothing is configured in this router by default), the Watchdog Timer (pings the Google server 8.8. zaglyuchit), made a fine adjustment of WiFi according to my conditions, and decreased the transmitter power from 1 watt to 0.1 watt (decibels from 27 to 17). Completely content. I am certain that now I will forget about the installation process and the inconsistency of the 3G-4G router until such time as I want to set up something new for my home network. I am confident that this will happen. So, in addition to that, I will need to configure my ZTE MF823 Beeline modem that serves as a backup. According to the information available on the network, everything is set up properly. As an aside, is it possible for me to connect two modems to the hub so that there will be two channels, one of which will serve as the primary and the other as the secondary? I'm sure Mikrotik can handle it!
