  • I have installed Ubuntu 18.04 in my Lenovo laptop.

  • It does not show up the WiFi options.

  • I tried downloading the drivers and installing them in the way as described here Wi-Fi not working on Lenovo ThinkPad E570 (Realtek RTL8821CE). But nothing in use.


  • Whenever i try to use make command, I get

  • The make command reports gcc is missing. If you want to compile the driver, install build-essential package.

  • Before going further, are you sure you have the exact same device? Even same models can come with different WiFi cards (and other parts, of course).

  • I suggest that you: sudo apt install libelf-dev and try again.

  • The make command reports gcc is missing. If you want to compile the driver, install build-essential package.

  • Before going further, are you sure you have the exact same device? Even same models can come with different WiFi cards (and other parts, of course).

  • I suggest that you: sudo apt install libelf-dev and try again.
