proper driver for your wifi is: rtl8188fu and not the rtl8188gu … so uninstall it, install kernel headers if you didnt, and install the proper driver:
pamac build 8188fu-supremegamers-dkms-git
(this is the latest version)
reboot
This is the output after i install this

for kernel headers here is the output

vulkan-headers 1:1.3.227-1
and here is output of my Manjaro system’s kerne
uname -r

still its not working please let me know how to install correct headers. I am new to linux
In that case I would advice to rename the already present file I guess

Build it:
pamac build 8188eu-dkms-git
Note that the driver is included in the kernel, but not for your device enabled on anything higher or lower than kernel 5.15:
But Kernel 5.15 have it enabled by default:
So on kernel 5.15 it should work.

Please install kernel 5.15 and reboot:
sudo mhwd-kernel --install linux515
on that kernel it should work out of the box.
Check which kernel your are running:
uname -r
There’s yer problem:
Installing headers for currently installed kernels
pamac install $(pamac list --installed --quiet | grep "^linux" | grep "^linux[0-9]*[-rt]*$" | awk '{print $1"-headers"}' ORS=' ')
And then try again.
Or what @megavolt said:

Again same error. I installed
pamac install $(pamac list --installed --quiet | grep "^linux" | grep "^linux[0-9]*[-rt]*$" | awk '{print $1"-headers"}' ORS=' ')
it executed successfully with no error

Looks like the device has 2 modes. You need to switch to wifi mode. Not sure here, but you need to set it with the terminal command usb_modeswitch somehow.
The Realtek RTL8188FTV-VB-CG is an 802.11b/g/n 2.4G single-chip that integrates Wireless LAN (WLAN) and a network USB interface (USB 1.0/1.1/2.0 compatible) controller
https://www.realtek.com/en/products/communications-network-ics/item/rtl8188ftv
Also to load the driver run this:
sudo modprobe -v r8188eu
execute this
sudo modprobe -v r8188eu
still not resolved. I don’t know how to switch to wifi mode. Also in system settings i cannot see wifi setting and under connections section i am just seeing wired connection1 which is my mobile connected to pc via usb tethering. do i need to setup wifi here ?
It’s been two days i am not able to troubleshoot this issue
According to this page:
The device is supported by kernel versions from 5.15 to 5.16 according to the LKDDb
So try installing version 5.15, as @megavolt suggested:
mhwd-kernel --install linux515
If you already have it installed, and it’s still not working in said kernel, uninstall all drivers you installed, make sure it’s not blacklisted, and reboot to test.
However, you are in excellent hands with @megavolt there, so continue following his advice before attempting mine.
i already have installed
mhwd-kernel --install linux515
uname -r
5.15.78-1-MANJARO
could you let me know how to do this?
**uninstall all drivers you installed, make sure it’s not blacklisted, and reboot to test.**
i am confused. Do i need to uninstall this?
pamac build 8188eu-dkms-git
???
It would seem so:
pamac remove 8188eu-dkms-git
…since it already is included in that kernel version. 
1 Like
removed it successfully.
can i reboot and build it again?
I don’t think you need to rebuild.
Let’s just make sure the driver/module isn’t blacklisted before rebooting. Please provide the output of:
cat /etc/modprobe.d/*
here is the output
cat /etc/modprobe.d/*
zsh: no matches found: /etc/modprobe.d/*
Looks promising. Just to make sure I’ve got it right, not you - me, please provide the output of:
ls /etc/modprobe.d/
