Parrot os upgrade is not showing any wifi list

[Nagesh_Katna]

Briefly describe your issue below:
I just installed parrot os on my new HP laptop and I performed the first upgrade on it. After the upgrade system worked ok until I didn’t restart it. When I restarted my system after upgrade I couldn’t get any wifi. I searched a lot online about the issue and ran a few commands like

sudo lshw -C network
and got the output as

I also ran ifconfig and it doesn’t show me wlan0. it just showed me

Please help me to solve this problem. Thanks

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)
Home edition version 4.6

What method did you use to install Parrot? (Debian Standard / Debian GTK / parrot-experimental)
I installed it through the installer
Configured to multiboot with other systems? (yes / no)No

Hello

1. sudo apt-get install linux-headers-generic build-essential git
2. git clone https://github.com/lwfinger/rtlwifi_new
3. cd rtlwifi_new
4. make
5. sudo make install
6. sudo modprobe rtl8723be

• This rtl8723be in last command was the driver I required. There are many other drivers of realtek in rtlwifi_new. For me, rtl8723be was required, you may require some other driver. To check which driver you need, give command lsusb and search the output list for something like 0bda:b728 Realtek Semiconductor Corp. This b728 can be something else, and this will determine driver required. Google for more info.

Thank you for your reply. On running the command lsusb I got the following output.
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 0bda:b00b Realtek Semiconductor Corp. Bluetooth Radio
Bus 001 Device 003: ID 04f2:b67f Chicony Electronics Co., Ltd HP TrueVision HD Camera
Bus 001 Device 002: ID 04f3:2793 Elan Microelectronics Corp. Touchscreen
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

So which one should it get according to the output? rtl8822be will work?

have you dowonloaded the drivers… if so
i think
make
and
sudo make install will chose it automatically for you…
try it…
