Eu tenho o modem USB huawei E1732 e estou usando um parceiro móvel com ele (fornecido pelo fabricante).
Recentemente, o modem começou a desconectar e a rede não aparece depois que ele é desconectado, e eu tenho que removê-lo e reinseri-lo para que ele funcione.
O que devo fazer para evitar que ele se desconecte novamente com frequência?
Existe também alguma maneira de controlar o meu modem USB usando o terminal?
