problema

português

Eu tinha 14,10 correndo bem na minha latitude da Dell até que a unidade se apagasse em mim. Eu reinstalei e tudo parece bem, exceto que "Ativar WiFi" só aparece (e me permite se conectar à minha rede WiFi) quando eu inicializar a partir do CD de instalação. Quando eu inicializo a partir do disco rígido, minha rede WiFi é listada em Editar Conexões com todas as mesmas configurações que estão sendo exibidas quando eu inicializo a partir do CD, mas não posso usá-lo.

Eu acho que isso é diferente de WiFi funciona no CD ao vivo, mas não quando eu inicializo de HD Porque tudo funcionava bem com a mesma máquina, BIOS e lançamento do Ubuntu há uma semana e também porque eu não recebo "Rede desativada" quando Execute a rede sudo lshw -c.

A saída LSMOD ao inicializar do CD é muito mais que eu estou supondo que um desses módulos é o que está fazendo a conexão WiFi possível. Alguém pode me dizer qual e como fazer parte do sistema de disco rígido?

sudo lshw -c rede # depois de inicializar a partir do CD e antes de conectar a WiFi

I had 14.10 running fine on my Dell Latitude until Unity flaked out on me. I reinstalled and everything seems fine except that "Enable Wifi" only shows up (and lets me connect to my wifi network) when I boot from the installation CD. When I boot from the hard disk, my wifi network is listed in Edit Connections with all the same settings that are showing when I boot from the CD, but I can't use it.

I think this is different from Wifi works on live cd but not when I boot from hd because it was all working fine with the same machine, BIOS, and Ubuntu release a week ago and also because I don't get "network DISABLED" when I run sudo lshw -C network.

The lsmod output when booting from the CD is so much longer that I'm guessing that one of those modules is what's making the wifi connection possible. Can anyone tell me which and how to make it part of the hard disk system?

The following gives me the same output whether booting from CD and from hard disk

lspci -nnk | grep 14e4

02:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter [14e4:4727] (rev 01) 

One other note: when I connect it directly to the router with a cable, it's on the internet just fine.

No output from rfkill list all.

I did a purge bcmwl-kernel-source, update, and new install as described at http://ubuntuforums.org/showthread.php?t=2214110. I did see this when I did the update:

DKMS: install completed. modprobe: ERROR: ../libkmod/libkmod.c:557 kmod_search_moddep() could not open moddep file '/lib/modules/3.16.0-30-generic/modules.dep.bin' update-initramfs: deferring update (trigger activated) Processing triggers for initramfs-tools (0.103ubuntu8) ... update-initramfs: Generating /boot/initrd.img-3.16.0-23-generic 

Thanks,

Bob

Você pode ter que instalar o Linux-firmware sudo apt-get install linux-firmware e possivelmente remover um casal módulos, verifique o post http://ubuntuforums.org/showthread.php?t=2214110 Em caso especial # 1 para mais detalhes

Se funcionar, agradeço ao Chili555

 

You may have to install linux-firmware sudo apt-get install linux-firmware and possibly remove a couple modules, Check the post http://ubuntuforums.org/showthread.php?t=2214110 under Special Case #1 for more details

If it works, thank Chili555

Eu acabei tendo o mesmo problema com o meu laptop, e estava enlouquecendo para reinstalar o Ubuntu. Eu tentei cada solução que tenha "wifi" nele. Mas depois de um longo tempo, eu apenas corri para uma página que menciona a diferença entre apt-get update e apt-get upgrade . Então eu tentei. Voila! Meu Wi-Fi é milagrosamente de volta depois de uma reinicialização. Então, para novos usuários do Linux, como eu, que instalaram uma cópia desatualizada do Ubuntu. Primeiro faça o seguinte antes de prosseguir para outras soluções.

        sudo apt-get update       sudo apt-get upgrade    

Espero que isso ajude! Espero que eu não consiga downvotes por uma resposta tão simples.

 

I ended up having the same problem with my laptop , and was going mad at me for reinstalling ubuntu . I tried every solution that has " WIFI " in it . But after a long time , i just ran into a page which mentions the difference between apt-get update and apt-get upgrade . So i tried it out . Voila ! My Wifi is miraculously back after a reboot . So for new linux users like me who have installed an outdated copy of ubuntu . First do the following before proceeding to other solutions .

      sudo apt-get update       sudo apt-get upgrade 

Hope this helps ! Hope i wont get downvotes for such a simple answer .
