Hi, I installed Ubuntu 18.04 but it does not have wireless and I can not connect to the Internet. In the additional drives section, there were two options, one of which was Broadcom, but it could not be installed.please guide me.
In case you are using Broadcom Limited BCM43142 as a network controller, run the following command to install the package:
sudo apt install bcmwl-kernel-source
sudo modprobe wl
If it did not solve, restart the server and type the commands below
lspci -knn | grep Net -A3
rfkill list
Good Luck.
