Ubuntu – Can’t enable the proprietary drivers for Broadcom BCM43142 wireless after installing Ubuntu 14.10? Offline package required


I have installed the new Ubuntu 14.10 on my Dell Inspiron 3521.

I was able to use my wifi in the Boot Live Stage and during the Installation phase by enabling the BroadCom BCM 43142 proprietary drivers.

But after installation I can't enable the proprietary drivers.

I can see the drivers listed there and when I select the option to use them and click Apply, the progress bar starts going ahead but stops in process and the 'Do not use them' option gets reselected.

I have searched some questions here according to which I must connect my laptop with an ethernet cable to get my wifi drivers working.

But I don't have any ethernet cable at present with me. I can only use the wifi on my second laptop.

Is there any other way to get the drivers working or Is there any offline installer like a .deb file for the drivers?

If anyone knows, please help!

I've reinstalled ubuntu thrice but the problem remains same.

Do you still have the install USB or DVD? Insert it and drill down to pool > restricted > b > bcmwl and drag bcmwl-kernel-source to your desktop. Do the same with pool > main > d >dkms and drag dkms to you desktop. Then install:

cd ~/Desktop
sudo dpkg -i dkms*.deb
sudo dpkg -i bcmwl*.deb

Reboot and tell us if your wireless is working.
