Hey Guys, I'm running Kali Linux 2018.2 via Live USB in my Lenovo Y510p laptop. Unfortunately I'm not able to get the Wifi working. OS is not detecting Internal Wireless Adapter and showing No WiFi adapter found.

My Wireless Card is Broadcom Limited BCM43142 802.11b/g/n (rev 01). Ifconfig shows only eth0 and loopback interface and iwconfig shows no wireless extension.

I tried running few basic commands in order to troubleshoot the issue. Please find the output below. Any help to get this issue resolved will be appreciated.

kuber@kali:~$ ifconfig

kuber@kali:~$ iwconfig
