How do I make Broadcom Corporation BCM43142 wifi card work with Netgear WNR614 N300 Wi-Fi Router on Ubuntu 16.04? The laptop is Dell Vostro 2520. Details of wireless card pasted at ubuntupastebin

  • I think what you really mean to ask is "How do I make Broadcom Corporation BCM43142 wifi card work"? ie, there are no Ubuntu drivers for your router to the best of my knowledge. – WinEunuuchs2Unix Sep 19 '16 at 3:51
  • I tried many things including rm /etc/modprobe.d/blacklist-bcm43.conf. I don't know which of my action did it. So I can't post anything as an answer. Now it is working. – Jayadevan Sep 19 '16 at 6:37

Have you installed wl? This is the broadcom proprietary driver.

According to this link, your driver is supported by wl (broadcom sta driver) but not b43 (reverse engineered driver firmware extractor).

To activate wifi for your BCM43142:

sudo apt install bcmwl-kernel-source
