# rtl8723bu Driver for Realtek RTL8723BU Wireless Adapter with Hardware ID `0bda:b720` # How to use? ## Get the source first. Get it from Github repository with the following command in the Linux terminal. ``` git clone https://github.com/lwfinger/rtl8723bu.git cd rtl8723bu ``` Or get it as zip archive. Note: If you use the zip format, you will need to download the entire source EVERY time it is changed. By contrast, a 'git pull' will get only the changed part. In addition, the git version will be able to access all branches, whereas the zip version only handles one branch. ``` wget https://github.com/lwfinger/rtl8723bu/archive/master.zip unzip master.zip && rm master.zip cd rtl8723bu-master ... Note: The code in branch v4.3.16 is better than that in master. Get that with git clone https://github.com/lwfinger/rtl8723bu.git -b v4.3.16 ``` ## Concurrent or Non-Concurrent Mode By default driver operates the hardware as a station AND as an access point *simultaneously*. This will show two devices when you run the `iwconfig` command. If you do not want two devices (station and an access point) *simultaneously*, then follow these instructions. - Step 1: Run the following command in the Linux terminal. ``` nano Makefile ``` - Step 2: Find the line that contains `EXTRA_CFLAGS += -DCONFIG_CONCURRENT_MODE` and insert a `#` symbol at the beginning of that line. This comments that line and disables concurrent mode. ## Manual install Run the following commands in the Linux terminal. ``` make sudo make install sudo modprobe -v 8723bu ``` This driver can not work with the standard driver rtl8xxxu, thus you need to blacklist it. Run the following command ... sudo nano /etc/modprobe.d/50-rtl8xxxu.conf ... Add a single line: blacklist rtl8xxxu ... ## Automatic install using DKMS If you don't want to worry about building/installing driver after kernel update, use this scenario. For Ubuntu/Debian install DKMS package using command `sudo apt install dkms`. Then run following commands in terminal ``` source dkms.conf sudo mkdir /usr/src/$PACKAGE_NAME-$PACKAGE_VERSION sudo cp -r core hal include os_dep platform dkms.conf Makefile rtl8723b_fw.bin /usr/src/$PACKAGE_NAME-$PACKAGE_VERSION sudo dkms add $PACKAGE_NAME/$PACKAGE_VERSION sudo dkms autoinstall $PACKAGE_NAME/$PACKAGE_VERSION ```
