Let's see if the system recognize your dongle.

Yes, you can see here the system is showing my wifi adapter at the top. What should I do now please tell me.

[Storm]

1. Is your "secure boot" in BIOS disabled? If not disabled it, it may conflict with your dongle.

2. Try this (it may be a hit'n'miss), requires net connection to execute and disabled secure boot;

sudo apt install git build-essential
git clone https://github.com/lwfinger/rtw88.git
cd rtw88
make
sudo make install
sudo modprobe rtw_8723de

[rrajbhar]

Sir, I tried this process as well but it did not make any change. What shall I do now?

[Storm]

Okay, lets try another driver for you dongle;

sudo apt-get install build-essential git dkms linux-headers-generic
git clone https://github.com/kelebek333/rtl8192fu-dkms
sudo dkms add ./rtl8192fu-dkms
sudo dkms build rtl8192fu/5.8.6.2
sudo dkms install rtl8192fu/5.8.6.2

Do we actually know what specific chipset the OP's dongle has, other than it is Realtek?

Note this "How To" post dated yesterday re certain USB wifi chipsets and drivers.

[How to] install USB wifi RTL8812BU / RTl8822BU drivers - manual

If you have a USB wifi card with the RTL8812BU / RTL8822BU chipset, here is how to install it in Zorin OS 16. Works perfectly. sudo apt update sudo apt install -y dkms git build-essential mkdir -p ~/src cd ~/src git clone https://github.com/morrownr/88x2bu-20210702.git cd ~/src/88x2bu-20210702 sudo ./install-driver.sh Rebooting is strongly recommended when ask.

Sir I have tried this method as mentioned by you but still I am getting the error of "wifi adapter not found".

[Aravisian]

Is this the driver you are using?

GitHub - kelebek333/rtl8192fu-dkms: RTL8192FU driver for Linux

[rrajbhar]

Yes, I am using this driver. But it is not working please help.

[Aravisian]

What is the output of

sudo apt install inxi

inxi -N

[rrajbhar]

I am seeing this. What should I do now please tell me.

[Aravisian]

USB network - is that a Wifi Dongle?

[rrajbhar]

Yes this is a wifi dongal.

[Aravisian]

Wifi Dongles are not always supported in Linux...
If you can provide the make and model, we can try looking it up.

[rrajbhar]

I do not know its model but I am sending you a photo of its cover, maybe you can find out something from it.

[Aravisian]

* Mini 2.4Ghz Wireless Wifi Dongle 600Mbps 802.11n USB connector.
* Compatible Operating Systems Windows 10/8/7/Vista/XP/2000
* Standard: IEEE802.11g,IEEE802.11b, CSMA/CA with ACK
* Frequency Range:2.4GHz-2.4835GHz
* Interface:USB2.0, Channel:13

Sadly, the device manufacturer did not build it to be compatible with Linux.

Are you using that Wifi Dongle because the onboard Wifi Chip is broken?

[rrajbhar]

Please tell me what should I do now?

[zabadabadoo]

Sadly we still do not know from your images what chipset is in that wifi adapter.
Do you have any more information you can find from the vendor ?

It says USB2. Are you usung a USB2 port. Try changing the USB port you haver it plugged into.
