Alright, you say it installed and I can see in your output it matches the chipset.
Let's try

sudo modprobe -r wl && sudo modprobe wl

[boatofcar]

modprobe: FATAL: Module wl not found.

[Aravisian]

Output of

apt list --installed | grep bcmw

[swarfendor437]

Zorin 17 is a fork of Ubuntu 24.04:

"Module wl not found in Ubuntu 22.04 typically occurs when the Broadcom wireless driver is missing or failed to load, often on laptops with Broadcom BCM43xx or similar wireless chips.

• Most Common Fix : Install the correct proprietary driver using:

sudo apt update && sudo apt install -y bcmwl-kernel-source

After installation, reboot your system.

• Verify the driver loaded after reboot:

dmesg | grep wl

You should see output like wl: loading out-of-tree module and wlan0: Broadcom BCM43b1... .

• Check for Secure Boot conflicts : If Secure Boot is enabled, it may prevent proprietary modules from loading. Try disabling Secure Boot in BIOS/UEFI if the driver still fails to load.
• Ensure kernel headers are installed :

sudo apt install linux-headers-$(uname -r)

This is required for DKMS to rebuild the module if the kernel was updated.

• Check for conflicting drivers (e.g., b43 , bcma , brcmsmac ):

sudo modprobe -r b43 bcma brcmsmac
sudo modprobe wl

If the issue persists, confirm your wireless chip with:

lspci -k | grep -A 3 -i "network\|wireless"

This confirms whether the correct driver is needed and helps identify conflicts.

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

@boatofcar

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

If that is the only output, that tells us it is Not Installed.

Please install it:

sudo apt update && sudo apt install bcmwl-kernel-source

Relay what you see in the terminal. It tells you what is going on. If it errors, relay that here.
If it completes successfully, relay that here.

[swarfendor437]

"The warning "WARNING: apt does not have a stable CLI interface. Use with caution in scripts" indicates that apt is designed for interactive use and may change its output format or behavior in future versions, which can break scripts.

Why the warning appears

• apt is intended as an end-user tool and may modify its command-line interface (CLI) between versions for better interactive experience.
• When apt detects its output is not going to a terminal (e.g., piped to grep , used in a script), it issues this warning to caution against relying on its output format.

Recommended solutions

1. Use apt-get instead for scripts

• apt-get has a stable CLI and is designed for scripting.
• All features of apt are available in apt-get , with the same underlying functionality.
• Example:

sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get install -y package-name

2. Suppress the warning (if you must use apt )

• To suppress the warning when standard output is not connected to a terminal, set the Apt::Cmd::Disable-Script-Warning option:

echo "Apt::Cmd::Disable-Script-Warning true;" | sudo tee /etc/apt/apt.conf.d/90disablescriptwarning

• This disables the warning permanently for all apt commands.

3. Filter the warning in a pipeline

• Use 2>&1 | grep -v to remove the warning line:

apt list --upgradable 2>&1 | grep -v "stable CLI interface"

Best Practice

• Avoid apt in scripts . Use apt-get , apt-cache , or dpkg-query instead.
• The apt command is safe for interactive use but not recommended for automation due to potential future changes in output or behavior.

It seems to have completed, though it did end off with this and Im not sure if that conflicts with anything

Did you use apt-get when installing?

[Aravisian]

Now try

sudo modprobe -r wl && sudo modprobe wl

These can be ignored for now:

Some of us will occasionally experience the i915 "Possible Missing Firmware" warning. EDIT: A recent Update may make some of this Obsolete. If you are reading this after the updates released by 16 Dec 2021 and still having Firmware Warnings, perhaps the below will help you. I gathered all the listed files into one directory and this can be handled here: However, this only covers users with the i915 modinfo warning. Others have the AMD warnings and so forth.

@boatofcar

6.8.0-94-g

I thought you said you switched to 5.15 Kernel when you loaded Zorin OS 17.3...

[boatofcar]

Ach!! I can’t believe i missed a crucial detail apologies.

I assume its okay to move forward with
sudo apt install linux-image-5.15.0-83-generic linux-headers-5.15.0-83-generic linux-modules-5.15.0-83-generic linux-modules-extra-5.15.0-83-generic ?

[Aravisian]

Let's start with

apt search linux-image-5.15

to ensure it is in the repo..

[boatofcar]

The output is too long for the text limit so I am including a screenshot

[Aravisian]

Ok, let's try

sudo apt install linux-image-5.15.0-83-generic linux-headers-5.15.0-83-generic linux-modules-5.15.0-83-generic linux-modules-extra-5.15.0-83-generic

it may be listed near the bottom of your output...
