Hi, please do:

Code:

sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-source

Then:

Code:

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

Then reboot.
Thanks

merin@merin-M15x:~$

but now there is some difference, i can see a tab called wireless in the network settings, and i see available network, but selection on dose not ask password or do nothing.

but even now i dont get anything for dmseg for iwl..

but get the below for rfkill

Code:

merin@merin-M15x:~$ rfkill list all
0: brcmwl-0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

eth0      Interface doesn't support scanning.

nothing happened !

Code:

merin@merin-M15x:~$ lsmod | grep b43
merin@merin-M15x:~$

As i said earlier, i had tried to connect to my wifi, but once you select there is no place to enter password, and nothing happens. and also i tried to switch on and off the wifi switch on my laptop.

Code:
