Problema con placa wifi Broadcom 4313n (Problem with Broadcom 4313)

Asked by Daniel Pérez Gómez on 2011-05-18

Hola soy muy nuevo en linux. Compré una notebook HP G42-470 LA, la cual viene con windows 7 home basic. Como quería probar linux instale la version 10.04, con la opcion de elegir entre los dos sistemas operativos cuando inicio la sesion.

El problema está en que linux no me detecta la placa wifi (Broadcom 4313 802.11 b/g/n). El bluetooth es detectado normalmente. Busque en google sobre el problema y habia una solucion que consistía en descargar un driver desde la pagina de broadcom (hybrid-portsrc_x86_64-v5_100_82_38.tar.gz) y luego ejecutar unos comandos en el terminal (de memoria porque no tengo idea de qué significa). El hecho es que no hubo ningun cambio.

Les agradecería que pudieran ayudarme.

Saludos

Hello I'm new in linux. I bought a HP G42-470-LA notebook. This computer uses windows 7 home basic. I wanted to try linux so i installed the version 10.04, with the option of booting with the 2 operating systems

The pŕoblem is that linux doesn't detect the wifi hardware (Broadcom 4313.802.11 b/g/n). Bluetooth works right. I googled t and there was some solution consisting in install a driver from the broadcom page (hybrid-portsrc_x86_64-v5_100_82_38.tar.gz) and then write some command in terminal (i have no clue of what i did). The fact is that there wasn't any change.

I would like some help.
Thank You

Cheers

pls run in a terminal cmd as follows

lspci -vnn

and copy/paste output here. pls consult

https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx

that will highlight the driver needed for a particular/your wifi adapter identified by the cmd above.

Hello Peter i run that command

This is the result

have u tried :
system > administration > Hardware Drivers ?
let me know...

peter b (b1pete) said : #4

this is your adapter

02:00.0 Network controller [0280]: Broadcom Corporation Device [14e4:4727] (rev 01)

BEFORE ANYTHING ELSE pls boot into win and make sure that

.....
miniPCI

*IMPORTANT* If dual-booting Windows and Ubuntu, be sure to enable the card (wireless light is on) in Windows before booting Ubuntu, otherwise it will not work.
.......

is indeed the case according to

https://help.ubuntu.com/community/HardwareSupportComponentsWirelessNetworkCardsBroadcom

the same url above lists your wifi adapter BCM4313 as supported with STA driver; same is also stated, together with instructions, on the url that I recommended on my first post ie https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx

question pls - if you have a WIRED ethernet connection (PC - router) do you have a net connection ?

pls run cmds as follows

sudo ifconfig
sudo iwconfig

and copy/paste their output here. tu.

Hello guys. Thank you very much for your help.

I did what alex said and worked perfectly. This downloaded a "privative" driver from an ubuntu page. Installed the driver required and works well.

Peter, sorry i passed that line and didn't read it. Yes, i have a wired connection to another pc with windows XP through an ethernet cable.

Cheers
Daniel
