( Uma questão relacionada encontrada aqui )
Eu tenho usado 11.04, agora 12.04 LTS, e se houver solução, não quero fazer upgrade desse LTS.
O primeiro problema é que o gerenciador de rede / rede se comporta de maneira errada:
- quando estou com bateria, o WiFi conecta-se (a banda larga móvel também), mas nenhuma rede pode ser acessada, como quando algo atinge o tempo limite. Se eu conectar o carregador de CA, ele imediatamente começará a funcionar.
- normalmente apenas lista as opções: ativar rede, ativar rede sem fio, ativar banda larga móvel, editar redes & amp; informações de rede, não há listas de redes disponíveis, etc ...
Bluetooth :
- O Bluetooth sempre é ligado na inicialização, mas quando eu o desligo em outro 12.04 LTS, ele se lembra e não liga na inicialização.
Conclusão: este laptop não é mais móvel; ele exige que o carregador AC se conecte a redes.
O que tentei resolver o problema principal?
- Atualize o gerenciador de rede para a versão mais recente do PPA diário : 0.9.6.0 ~ git201208071622. 5714-0 ~ pkg562 ~ precise1
- substitua o driver sem fio pelo b43, mas ele não era suportado ( Como faço para que uma placa sem fio Broadcom BCM4313 funcione? )
- atualize o BIOS. Agora eu tenho a versão A05, a mais recente é a A06, mas não consegui porque não encontrei o arquivo HDR nos repos da Dell (não há system_bios_ven_0x1028_dev_0x0470_version_A06 dir), e eu não poderia gerar se a partir do executável do Windows (wine / writehdrfile / nopause agora não funciona) - tutorial original está aqui
- instale um software / firmware da Dell:
ii dell-dup 1.1.3-0ubuntu2 A firmware-tools plugin for Dell DUP images
ii firmware-addon-dell 2.2.9-0ubuntu1 A firmware-tools plugin to handle BIOS/Firmware for Dell systems
