Hi, I have a new RUT950 H that is unable to connect to 4G network if SIM is in slot1. In slot2 works fine. Firmware is RUT9XX_R_00.06.04.1. I also tried reset to factory default but it doesn't work. I have another new RUT955 H (firmware RUT9XX_R_00.05.03.2) and the same SIM and configuration works fine with sim in slot1. Is the RUT950 defective? Can anyone help me understand? Thanks
