I was using windows 7 before the update and before the update the driver was working good it was detecting all the WiFi networks but after the update there is a notification which is 'NO WIFI - ADAPTER FOUND'. My WIFI driver model is -07:00.0 Network controller: Broadcom Inc. and subsidiaries BCM43142 802.11b/g/n (rev 01)

Please help me, I have to attend my classes, so please help me as soon.

Thank you!

You'll need to install the Broadcom STA driver for this device. So long as you have a wired network connection, you can do it like this:

  1. Open Terminal (if it's not already open)
  2. Update Apt:
    sudo apt update
  3. Remove the current wireless driver (if it's installed):
    sudo apt purge bcmwl-kernel-source
  4. Install the Broadcom STA drivers:
    sudo apt install broadcom-sta-source broadcom-sta-dkms broadcom-sta-common
  5. Reboot

This should allow you to use the wireless device.
