I have a Lenovo G710 and I am unable to install my wireless card. Here are the details:

uname -a:
Linux ubuntu 3.8.0-34-generic #49~precise1-Ubuntu SMP Wed Nov 13 18:05:00 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

lspci | grep Network
07:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01)

I have tried several advices onlines but still not able to make it work. The Ethernet card works perfectly ok. Even my bluetooh device works ok.

How can I fix this?

I am really new with Linux.

Firstly try this guide (3rd post):

When it wont work this one:

For information: apt-get, yum and zypper have the same functionality and change depending on the linux you have (replace them until command work).

If the guides don't work please post the output of dmesg | grep -i bcm as a comment.

Took me one day to get my BCM43142A0 (with openSUSE) to work properly.

Hi sorry for the late answer. I tried your links before I post. Unfortunately they didn't work. Here is the result that you have requested: root@ubuntu:~$ dmesg | grep -i bcm [ 1.835892] usb 3-8: Product: BCM43142A0 – linux-user Jan 2 '14 at 21:56
