new linux user here. I am not able to find wifi on Dell XPS 13 9343 laptop connected to internet via USB tethering. Wireless card - Broadcom BCM4352 802.11ac Dual Band (14e4:43b1) rev 03. I tried to install bcmwl-kernel-source and firmware-b43-installer but getting error unable to locate package for both commands.
Please help!
These packages are provided by the restricted and multiverse repositories. These repositories should be enabled by default.
First, run
sudo apt update
before trying to install packages:If you still cannot locate the packages, then you need to enable the restricted and multiverse repositories:
Then, install the packages:
Also and unless you have a reason to have the universe repository disabled, you should probably make sure the universe repository is enabled as well to prevent similar issues in the future:
To explain further, the
sudo apt update
command updates your list of available packages. This command essentially checks to see if updates are available by comparing the list of available packages on your computer to the most recent list of packages available from the repositories.When you first install Ubuntu, a complete list of available packages may not exist on your computer.
It should be noted however, that this command does not update any software. As explained, the update command only updates the list of available packages. To actually update the software on your system, you must also run
sudo apt upgrade
orsudo apt full-upgrade
after you runsudo apt update
like in the following example:or
For most users,
sudo apt full-upgrade
is the best option. However, if this is a production computer, it may be best to runsudo apt upgrade
instead as this may hold back some updates that you may want to hold off on until whatever project you're working on is finished.It is recommended to do this daily to avoid issues.
UPDATE:
Finally, try enabling the kernel module:
and disable secure boot.
