I've searched a lot for my driver but didn't get any solution. I referred to this link where it gives solution under "Special Case #1 " but that doesn't give me a clear solution. here is few info if it is required:

lspci -vnn | grep Network gives

00:19.0 Ethernet controller [0200]: Intel Corporation 82577LM Gigabit Network Connection [8086:10ea] (rev 05) 02:00.0 Network controller [0280]: Broadcom Corporation BCM43224 802.11a/b/g/n [14e4:4353] (rev 01)

iwconfig gives

eno1 no wireless extensions.

lo no wireless extensions.

enp0s29u1u2 no wireless extensions.

I'm on Ubuntu 16.04 LTS. also this: image link

Your image link suggests that the wrong driver is installed. Please remove it. From the terminal:

sudo apt-get purge bcmwl-kernel-source


Check to see that the correct driver, brcmsmac loaded:

lsmod | grep brcmsmac

Check for informative clues in the log:

dmesg | grep brcm
