I installed Ubuntu 16.05 alongside Windows 10 on a Dell Inspiron 3543 laptop. Installation was successful, but could not get the WiFi connected to the internet.

I can see my SSID being displayed on the drop down menu, but WiFi doesn't work after I click it and enter the WiFi password. The WiFi icon is displayed with an "empty WiFi" sign.

Here is the output from running the Wireless Info Script

How can I fix this so that I can access the internet?

I followed instruction from the duplicate page step by step and still have the issue.

I have Dell Inspiron 3543 as well.

Connect to the internet with a cable or connect to a Wi-Fi network with your smart-phone and tether the connection over a usb cable.

Run sudo apt update if you haven't already after installing Ubuntu.

Then sudo apt-get install bcmwl-kernel-source

This should make wireless connections work.

Note: Bluetooth is also possible to configure, though it's harder, and there is not so much help out there (I did get bluetooth to work once)

Update

You can as well download the package here:

https://packages.ubuntu.com/jammy/bcmwl-kernel-source

Though make sure to select the right version! The link I've provided leads to the package for jammy (22.04LTS) and you might be on a different one. You can select it at the top of the page.

This is useful if you can only access internet from another device. After downloading – you can simply transfer the package using a USB flash drive or your phone and install it using dpkg. I.e.:

dpkg -i bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu4_amd64.deb
