Good evening,
I have a MikroTIK SXT LTE6 kit. The router does not detect the SIM card. The card is functional. It also does not detect other sim cards. I am enclosing a video. In 17 seconds, all LTE LEDs turn on and then turn off. Before that, all the LEDs were on. I tried to upload the software again via netinstall but after clicking Install nothing happens. That is, there is no formatting and the button can be clicked again. Requesting support what should I do first.
