System: HP ab516TX

sudo lshw -C network

gives

*-network UNCLAIMED     
       description: Network controller

and lscpi gives

I have checked the following topics, they aren't helping:

No WI-FI in Ubuntu 16.04 gnome [duplicate]

How do I install BCM43142 wireless drivers for Dell Vostro 3460/3560?

New : Installing Broadcom Drivers

@Pilot6, Here you go. Yes I did read both of the articles. Also disable secure boot before trying to install the recommended driver.

lspci -knn | grep Net -A2

@Pilot6 I have followed the steps described at Installing Broadcom Wireless Drivers. No dice, the driver is not detected. Any ideas why? — Kartik Mudgal, Jun 12 '16 at 11:12
Please [edit] your question and add output of lspci -knn | grep Net -A2 terminal command. Did you read the related link? — Pilot6, Jun 12 '16 at 11:19
@Pilot6 Yes, I've read the articles you pointed to. PS: Edited the question to include the details. of {lspci -knn | grep Net -A2}.
PS: how do you include formatting in comments? — Kartik Mudgal, Jun 12 '16 at 11:31
For code formatting in comments, you can use backticks, ie. `some text ` will result in some text. — Jonas Czech, Jun 12 '16 at 11:38
Did you run sudo apt-get install bcmwl-kernel-source? Did you disable SecureBoot if applicable? — Pilot6, Jun 12 '16 at 11:42
@Pilot6 Yes, to both. I did however try to install bcmwl-kernel-source before I had asked this question, and thus had to --purge it first — Kartik Mudgal, Jun 12 '16 at 11:45
derp. I did not check. Sorry for wasting your time, I'll re-install it asap(now) — Kartik Mudgal, Jun 12 '16 at 11:49
@Pilot6 Ah, I've found out what the problem is: for some reason secure boot is not being disabled even after running sudo mokutil --disable-validation ,mokutil --sb-state shows SecureBoot enabled. Anything I can do to disable it? — Kartik Mudgal, Jun 12 '16 at 11:59
Please close this question. The error was due to mokutils not disabling SecureBoot. I had to do it through the setup options at boot This is a correct solution my problem — Kartik Mudgal, Jun 13 '16 at 05:01
