Sure and see what happens. Then you’ll have to connect back up if it doesn’t work.
OK Sir
So i’m not seeing the wireless adapter in the output.
what does this show
ip link

What about
rmmod ssb
modprobe wl
[ramesh@ramesh ~]$ rmmod ssb
rmmod: ERROR: Module ssb is not currently loaded
[ramesh@ramesh ~]$ modprobe wl
[ramesh@ramesh ~]$
I’m at a loss right now as i have got this BCM4312 working a few times for others. 
I take it you don’t have ethernet?
What happens with this
sudo wifi-menu
That should be the profile so click okay.
ob for netctl@wlan0\x2dAnjaneya.service failed because the control process exited with error code.

[ramesh@ramesh ~]$
sudo netctl start Anjaneya
sudo netctl enable Anjaneya
Sudo netctl start Anjaneya

LOAD = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB = The low-level unit activation state, values depend on unit type.
33 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'
Okay lets try this then
sudo netctl start Anjaneya.service
sudo netclt enable Anjaneya.service
sudo netctl start wlan0\x2dAnjaneya.service
sudo netctl enable wlan0\x2dAnjaneya.service
