BCM43142 WiFi not working in Ubuntu 14.04.2

Question

I tried many solutions given for other BCM43 drivers and nothing helped me!! I saw one guy posted that WiFi wont work for Wubi Ubuntu of BCM43142.

I do not have ethernet connection too in my home!! I use my own mobile hotspot for this! So WiFi is must for me... Buh unfortunately nothing worked for me!!

Anyone using WiFi in BCM43142 hardware?

My ubuntu is Wubi. If anyone got solution please help me.

The only step that you may do when connected to ethernet is sudo apt-get update; sudo apt-get install b43-fwcutter and then reboot. If doesn't work, then ask here again — 0x2b3bfa0, Apr 04 '15 at 08:10

The package bcmwl-kernel-source is correct for your device. If you still have the install DVD or USB, then you can find it and its prerequisite there. Navigate to pool > restricted > b > bcmwl and drag and drop the deb file to your desktop. Now navigate to pool > main > d > dkms and drag and drop dkms to your desktop. Now install both with:

cd ~/Desktop
sudo dpkg -i *.deb

Load the driver:

sudo modprobe wl

Your wireless should now be working.
