Broadcom BCM4312: Ubuntu 12.10 is not seeing my wifi

[huntja]

I got the Dell inspiron 1012 for my birthday and installed ubuntu 12.10 desktop through the usb method. once it was installed i clicked on the network icon to connect to wifi but it didnt see any wifis. I searched through the forums and found some answers but i dont know many technical terms and stuff for drivers and things. Could someone give me a very noob termed intructions for connecting to wifi? I'm such a noob at this

Hi,

you probably need to give a bit more details for the guys here at the forum to help you really.

As a couple of preliminary questions:
- does the network manager say that networking and wireless are enabled? if you right-click on the icon it will show both and they should have a tick next to them
- is your wifi card switched on? you need to press 'Fn+f2' combination to switch it on

if after these check for your network and if you still cannot see your network pls post the outputs of

lspci
lsusb
lsmod

[huntja]

network manager says nothing of wireless but networking is enabled.

no response to fn+f2

as for the commands (i assume you mean terminal)

you have a Broadcom Corporation BCM4312 modem and this is what you need to google for - I am not too familiar with these. You may want to start at http://ubuntuforums.org/showthread.php?t=1811184

After many hours searching the internet i dcided that it would be easier if I did a fresh install. Now, it sees the driver in the additional drivers page, but when i click "use this driver" it only half loads then stops and never moves again. Any fixes to this anyone?

Hi, lets see if we can make that birthday present
work like its is suppose to for you.
please COPY and paste the following commands.

lspci -nn | egrep '0200|0280"
lsmod
rfkill list all

please post the results
thanks.

[huntja]

sorry for the delay on the response haven't had a minute to do it forever. Anyway, when i pasted the commands into the terminal nothing was displayed. i typed lspci -nn | egrep '0200|0280" and it showed a >
same for the rest sorry if this wasnt what you were looking for.

After many months of searching I found these terminal commands once connected to the internet wired style entering these in the terminal gets the wifi to work!! so happy can't wait to start using linux to it's full potential.

sudo apt-get install linux-headers-generic
sudo apt-get install --reinstall bcmwl-kernel-source
sudo modprobe wl
