Hello out-there, long time no see.
Ok guys a really interesting issue here.

After update my Linux Mint installation, can't find my wireless NIC.
Here some commands outputs:

inxi -Fxz Network: Device-1: Intel driver: N/A port: 3000 bus ID: 00:14.3 IF-ID-1: docker0 state: down mac: <filter> IF-ID-2: enxd037452d23d5 state: unknown speed: N/A duplex: N/A mac: <filter> IF-ID-3: lxdbr0 state: unknown speed: N/A duplex: N/A mac: <filter> IF-ID-4: virbr0 state: down mac: <filter> IF-ID-5: virbr0-nic state: down mac: <filter>

sudo lshw -class network *-network UNCLAIMED description: Network controller product: Intel Corporation vendor: Intel Corporation physical id: 14.3 bus info: [email protected]:00:14.3 version: 30 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix cap_list configuration: latency=0 resources: memory:913a4000-913a7fff *-network:0 description: Ethernet interface physical id: 2 logical name: enxd037452d23d5 serial: d0:37:45:2d:23:d5 capabilities: ethernet physical configuration: broadcast=yes driver=cdc_ether driverversion=22-Aug-2005 firmware=CDC Ethernet Device ip=192.168.1.15 link=yes multicast=yes *-network:1 DISABLED description: Ethernet interface physical id: 3 logical name: virbr0-nic serial: 52:54:00:66:4f:d2 size: 10Mbit/s capabilities: ethernet physical configuration: autonegotiation=off broadcast=yes driver=tun driverversion=1.6 duplex=full link=no multicast=yes port=twisted pair speed=10Mbit/s

What I have try so far:

lsmod | grep ath sudo modprobe -v ath9 sudo modprobe -rfv ath9k

sudo add-apt-repository ppa:canonical-hwe-team/backport-iwlwifi sudo apt install backport-iwlwifi-dkms

sudo apt install linux-generic-hwe-18.04-edge


sudo apt-get install b43-fwcutter

Actually I tried anything I found out-there but no luck.

Any suggestion?

Thank you very much.

Can you boot into the previous kernel where it does show up, that way you could check what kernel driver and module it is using as well has the device information since it doesn't show up in your.
1. Boot into a previous kernel where your network device does show up.
2. Run: lspci -nn | grep -i net
3. Run: lspci -v (Then search for your network card and share what kernel module and driver is in use)
4. Share the output 2 and 3 here.

I assume your using the ubuntu mint, and not the debian mint , then the b43 drivers are already in the mint repositories [use software manager][but i cant see anywhere that you have a broadcom wi-fi] ...inxi -N should show it

Good day, @f33dm3bits

I tried to boot in older kernels but no success.
Actually I didn’t check for modules. I will revert.
Thanks.

@f33dm3bits and @brickwizard
Just a question on both of you.
Is there any possibility to delete the module/driver just because I installed neither driver for an external wifi device ?

If your network/wifi device was working before you updated the kernel than the driver was in that kernel and since the device is not showing and not working anymore it looks like that driver isn't in the kernel anymore and/or the firmware of that device was removed from linux-firmware. We can check that my going through the dpkg.log file. You could run the following and share the output.
Code:
sudo egrep "linux-[generic|firmware]" /var/log/dpkg.log | grep upgrade
I'm assuming you mean the device isn't showing up either as wifi or other network device anymore?

On shore or at sea at the moment, Capta?

Not that it matters, just finding an excuse to say

G'day

The modules won't load if the interface isn't showing up.

Hello guys. I found an interesting program in Linux Mint forum while I was looking for a solution.


Code:
wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && chmod +x wireless-info && ./wireless-info

Result of the above command, it returns a .txt file which include any info relevant to wifi. You can find mine as attached.

Thank you.

00:14.3 Network controller [0280]: Intel Corporation Cannon Point-LP CNVi [Wireless-AC] [8086:9df0] (rev 30)
The device is detected but it is not recognized as a wireless interface. Can you share the output of the following?
Code:
dmesg | grep iwlwifi
ls -ltr /var/cache/apt/archives | grep linux-firmware
I want to see what other linux-firmware packages are in your apt cache that way we could try installing an older version and if that doesn't work we could try having you install a newer kernel since according to this the device is supported from kernel 5.7 and up.
