I have a big problem.
I have just installed Ubuntu 19.04 on my computer (or laptop or notebook). But, the wireless driver isn't working. I have checked the settings, but there is no menu named "Wi-Fi".
Notebook model: Acer Aspire E 11
This is the complete report:
$ lspci -vnn | grep Network 02:00.0 Network controller : Broadcom Inc. and subsidiaries BCM43142 802.11b/g/n [14e4:4365] (rev 01) $ rfkill list all 0: acer-wireless: Wireless LAN Soft blocked: no Hard blocked: no 1: acer-bluetooth: Bluetooth Soft blocked: no Hard blocked: no 2: hci0: Bluetooth Soft blocked: no Hard blocked: no $ iwconfig lo no wireless extensions. enp3s0 no wireless extensions. $ sudo apt search bcmwl-kernel-source [sudo] password for juan: Sorting...

After I reinstall bcmwl-kernel-source. It's most done. But, I get this following message:
modprobe: ERROR: could not insert 'wl': operation not permitted
