First uninstall the bcmwl-kernel-source package by issuing the following command on a terminal:

sudo apt-get remove bcmwl-kernel-source

Install firmware-b43-installer and the b43-fwcutter packages if they are not installed

sudo apt-get install firmware-b43-installer b43-fwcutter

Type into terminal:

cat /etc/modprobe.d/* | egrep 'bcm'

Copy this and see if the term 'blacklist bcm43xx' is there

if it is, type cd /etc/modprobe.d/ and then sudo gedit blacklist.conf

put # in front of the line: blacklist bcm43xx

Now save the file then reboot.

Before you proceed, let's identify your wireless device. Please edit your question to add: lspci -nn | grep 0280 –  chili555 Jan 9 at 12:56
