  • The question which was answered before mine was about rtl8188fu however mine is about rtl8188ftv. I tried these steps before posting the question but it didn't work for me that's why I asked that question again.

  • I believe the device is covered by the driver r8188eu that's included by default in Ubuntu 22.04. Please edit your question to show the result of the termminal command: modinfo r8188eu | grep F179 and also: sudo dmesg | grep r81 Welcome to Ask Ubuntu.

  • It appears that the driver loaded and an interface was created: wlx00e04c818802. Does it see networks? nmcli device wifi list No need to post the result, just tell us if it does or does not see your network. If it does, can you click on the Network Manager icon and connect?

    Let's have a look at more diagnostics: sudo dmesg | grep -e r81 -e wlx Also: lsmod | grep 8188 Does it see your network if you stand right next to the router? nmcli device wifi list

As we see above, the built-in driver r8188eu does not work. Let’s try a better driver. With a working internet connection by ethernet, tethering or whatever means possible, open a terminal and do:

sudo apt update
sudo apt install –reinstall build-essential bc git dkms
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 /usr/lib/firmware/rtlwifi/

Now let’s blacklist the built-in driver:

sudo -i
echo “blacklist r8188eu”  >>  /etc/modprobe.d/blacklist.conf
echo rtl8188fu >>  /etc/modules
exit

Reboot.
