The support guy was very patient with me, but the bad news is that the problem persists.
I made a new connection to another wifi network and the system continues to act in the same way, it does not give me an ip in the network interface. The names and passwords are all different so as not to create conflicts. I don't know how to write code, I'm a normal user, not a computer engineer.
I need the router to connect to Wi-Fi networks and balance the load with the two SIMs. If this is not possible without going to technical support, please let them know.
