Meu modem de banda larga móvel funciona com o Kernel 3.2.0-58-generic # 88-Ubuntu SMP, no entanto, ele não consegue completar uma conexão com o novo Kernel 3.11. Alguém tem uma solução para habilitar o modem com o Kernel 3.11
A versão do Ubuntu é 12.04.4
O Modem é um Serria Wireless
Aqui estão alguns dados de registro

Uma excelente solução da Chandana. Ser citado:
Isso aconteceu devido a bugs (ou bug) no ModemManager 0.6.0.0 que acompanha o Ubuntu 12.10. Você pode remover esta versão do gerenciador de modem e fazer o downgrade para 0.5.2.
Para verificar a versão do gerenciador de modem:
% bl0ck_qu0te%faça o download da versão 0.5.2: link 64 --- i386
