Thank you Iowan for your time.
Sadly, that thread couldn't solve my problem.
Actually my wireless card is BCM 4353, which I couldn't find listed on any of such bcm related threads.
Here is the result when I ran lspci :

After referring the tutorial https://help.ubuntu.com/community/Wi...Driver/bcm43xx (which I found in the thread pointed by you), I installed b43-fwcutter package (though 4353 is not listed there particularly). Also ran apt update on bcmwl-kernel-source and dkms. bcmwl-kernel-source was updated, while dkms was already up-to-date. I still get the same error. The current jockey.log file (after installing fwcutter and running apt update) is here : http://pastebin.com/f3cf50669
