How to Fix Wireless problems on Dell Inspiron Laptops using Broadcom 43142 (BCM43142) and Ubuntu 12.10

It is a common problem for the Dell Inspiron Laptops using Broadcom 43142 (BCM43142) network card not to see wireless networks on Ubuntu 12.10.

But this can be solved in a few steps:

1. Download the Broadcom 43142 driver:
$ wget

2. Install the needed dependencies:
$ sudo apt-get install linux-headers-generic build-essential dkms

3. Install the downloaded BCM43142 driver:
$ sudo dpkg -i wireless-bcm43142-dkms_6.20.55.19-1_amd64.deb

This tutorial solved the wireless problem on Dell Inspiron 5520 and Dell Inspiron 5720.

Note: The driver I linked in the article is for 64 bit sytems (x86_64). To make it work on 32 bit systems, install ia32-libs:

$ sudo apt-get install ia32-libs

I am not sure that after installing ia32-libs, everything will work perfect, but you can try.

    I have edited the post to fit your needs.

    you are trying to install an 64bit program on an 32bit system.

    install ia32-libs and try to install the broadcom package with dpkg again:

    sudo apt-get install ia32-libs

    sudo dpkg -i wireless-bcm43142-dkms_6.20.55.19-1_amd64.deb

    OS : CentOS 7 (x64).
