Answer 1

I got the exact same issue in my Ubuntu 22.04.1 LTS. It was recognizing RTL8188FTV 802.11bUSB Wifi adaptor but not scanning any network.

So, What I did (after spending a whole day on it):

1. Install and configure the rtl8188fu driver by following this repo (I executed only following commands)

sudo apt-get install build-essential git dkms linux-headers-$(uname -r)
git clone https://github.com/kelebek333/rtl8188fu
sudo dkms add ./rtl8188fu
sudo dkms build rtl8188fu/1.0
sudo dkms install rtl8188fu/1.0
sudo cp ./rtl8188fu/firmware/rtl8188fufw.bin /lib/firmware/rtlwifi/

sudo mkdir -p /etc/modprobe.d/
sudo touch /etc/modprobe.d/rtl8188fu.conf
echo "options rtl8188fu rtw_power_mgnt=0 rtw_enusbss=0" | sudo tee /etc/modprobe.d/rtl8188fu.conf

2. Black List r8188eu driver in /etc/modprobe.d/blacklist.conf

Edit this /etc/modprobe.d/blacklist.conf file to add blacklist r8188eu at the end of file.

3. Finally reload the newly installed driver using following command sudo modprobe -rv rtl8188fu && sudo modprobe -v rtl8188fu
4. Now reboot the system.

Summary:

1. Install and configure a new driver rtl8188fu
2. then backlisted the already existed driver r8188eu
3. then reload the newly installed driver
4. reboot system.

That's all.
