wlan0 disappeared

Briefly describe your issue below:

I recently updated my laptop and when I rebooted it, my onboard wifi disappeared. Running ifconfig returns no wifi interface but I can access the internet through an external wifi adapter.

What version of Parrot are you running? (include version (e.g. 4.6), edition(e.g. Home//KDE/OVA, etc.), and architecture (currently we only support amd64)
I’m running version 4.7 on kernel 5.2.0-2parrot1-amd64. KDE version
What method did you use to install Parrot? (Debian Standard / Debian GTK / parrot-experimental)
Debian Standard
Configured to multiboot with other systems? (yes / no)
List your networking hardware (make, model, firmware version):
I’m not certain what internal wifi card I am using, but I know that it worked prior to my upgrade. My laptop is a Thinkpad E480.

It seems to be Realtek r8822be. I can see the device by running lspci, but it reads out that it’s an unassigned class, as opposed to a WiFi card and lshw -C network doesn’t pick up on it at all.

Yesterday my wlan0 disappeared again, you can try to fix it, the same way I did it. But make sure to find correct firmware for your adapter.

Yo, brother I’ve found this solution for you.
