-rtl8188fu for linux
-===================
+RTL8188FU driver for Linux kernel 4.15.x ~ 6.7.x (Linux Mint, Ubuntu or Debian Derivatives)
 
-rtl8188fu linux driver for wireless bgn device
+info: rtl8188fu support added to rtl8xxxu module of Linux kernel with version 6.2. 
 
-Note:
-This is an USB2 only adapter,  
-Source is ripped out of firefly source tree found at  
-https://gitlab.com/TeeFirefly/linux-kernel 
+------------------
 
-<u>If one USB-ID is missing, please mail me.</u>  
+## How to install
 
-build/load/function tested with v4.19  
+`sudo apt-get install build-essential git dkms linux-headers-$(uname -r)`
 
-Building and install driver
----------------------------
+`git clone https://github.com/kelebek333/rtl8188fu`
 
-for building type  
-`make`  
+`sudo dkms install ./rtl8188fu`
 
-for load the driver  
-`sudo modprobe cfg80211`  
-`sudo insmod rtl8188fu.ko`  
+`sudo cp ./rtl8188fu/firmware/rtl8188fufw.bin /lib/firmware/rtlwifi/`
 
-You need to install the needed fw with  
-`sudo make installfw`  
+------------------
 
-If you need to crosscompile use  
-`ARCH= CROSS_COMPILE= KSRC=`  
-while calling `make` i.e.  
+## Configuration
 
-`make ARCH="arm" CROSS_COMPILE=armv5tel-softfloat-linux-gnueabi- KSRC=/home/linux-master modules`  
+#### Disable Power Management
 
-Please use prefix **rtl8188fu** if you want to mail me  
-But please please don't, I have enough to do.  
-TIA  
+Run following commands for disable power management and plugging/replugging issues.
 
-Hans Ulli Kroll <ulli.kroll@googlemail.com>
+`sudo mkdir -p /etc/modprobe.d/`
+
+`sudo touch /etc/modprobe.d/rtl8188fu.conf`
+
+`echo "options rtl8188fu rtw_power_mgnt=0 rtw_enusbss=0 rtw_ips_mode=0" | sudo tee /etc/modprobe.d/rtl8188fu.conf`
+
+#### Disable MAC Address Spoofing
+
+Run following commands for disabling MAC Address Spoofing (Note: This is not needed on Ubuntu based distributions. MAC Address Spoofing is already disable on Ubuntu base).
+
+`sudo mkdir -p /etc/NetworkManager/conf.d/`
+
+`sudo touch /etc/NetworkManager/conf.d/disable-random-mac.conf`
+
+`echo -e "[device]\nwifi.scan-rand-mac-address=no" | sudo tee /etc/NetworkManager/conf.d/disable-random-mac.conf`
+
+#### Blacklist (alias) for kernel 5.15 and 5.16 (No needed for kernel 5.17 and up)
+
+If you are using kernel 5.15 and 5.16, you must create a configuration file with following command for preventing to conflict rtl8188fu module with built-in r8188eu module.
+
+`echo 'alias usb:v0BDApF179d*dc*dsc*dp*icFFiscFFipFFin* rtl8188fu' | sudo tee /etc/modprobe.d/r8188eu-blacklist.conf`
+
+#### Blacklist (alias) for kernel 6.2 and up
+
+If you are using kernel 6.2 and up, you must create a configuration file with following command for preventing to conflict rtl8188fu module with built-in rtl8xxxu module.
+
+`echo 'alias usb:v0BDApF179d*dc*dsc*dp*icFFiscFFipFFin* rtl8188fu' | sudo tee /etc/modprobe.d/rtl8xxxu-blacklist.conf`
+
+##### Then you must update initramfs
+
+For initramfs
+
+`sudo update-initramfs -u`
+
+For dracut
+
+`sudo dracut -q --force`
+
+##### Enable rtl8188fu module
+
+Run following command for up to kernel 6.1
+
+`sudo modprobe rtl8188fu`
+
+Run following commands for kernel 6.2 and up
+
+`sudo modprobe -r rtl8188fu`
+
+`sudo modprobe rtl8188fu`
+
+------------------
+
+## How to uninstall
+
+`sudo dkms remove rtl8188fu/1.0 --all`
+
+`sudo rm -f /lib/firmware/rtlwifi/rtl8188fufw.bin`
+
+`sudo rm -f /etc/modprobe.d/rtl8188fu.conf`
+
+
+------------------
+
+## How to install from PPA repository
+
+You can install rtl8188fu driver with following commands from PPA.
+
+for xUbuntu 16.04-18.04-20.04-22.04-23.04-23.10 / Linux Mint 20.x-21.x
