I have been trying since yesterday to get wifi working on my laptop. it was working fine till yesterday but has stopped working now. Actually the problem is it's not able to find my home wifi. It doesn't show my home wifi at all. I changed my modem yesterday and since then it has stopped working. I have done various things and it's all messed up as of now.

This is the configuration of my Driver :

Network controller [0280]: Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01)

Earlier I had installed the driver exactly as given over here: https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#b43142

The internet worked fine but when I changed my modem yesterday my laptop wasn't able to detect the new modem/wifi but the wifi works fine on my phone so the modem is configured fine. I followed quite a few things online but nothing seems to work.

This http://pastebin.ubuntu.com/7886319/ is the output of the script I ran according to this link My wireless/WiFi connection does not work. What information is needed to diagnose the issue?

And the out put of the following code 

sudo dpkg -s bcmwl-kernel-source

is on this link -->> pastebin.ubuntu.com/7890911/

Can someone please help.

Run in the terminal:

echo "blacklist brcmutil" | sudo tee -a /etc/modprobe.d/blacklist.conf

Then: 

sudo gedit etc/modules

and from that file remove brcmutil then save the file and reboot.

Reset the modem and router remove your network from network manager and reboot the computer to allow network manager to find your network.
