This device was reported by jaif in issue #256

If your system says that /lib/modules/...../build does not exist, you have not installed the kernel headers, you have done it incorrectly, or you are not running the kernel for which the headers have been installed. The necessary steps are dependent on which distro you are using. Creating a new issue and asking at GitHub will not be productive.

If a build fails that previously worked, perform a 'git pull' and retry before reporting a problem here. If you downloaded the source in zip form, then you need to get an entirely new source file. That is why using git, which downloads only the changed lines, is recommended.

Compiling & Building


To compile the driver, you need to have make and a compiler installed. In addition, you must have the kernel headers installed. If you do not understand what this means, consult your distro.


make all


sudo make install


The module can also be installed with DKMS. Make sure to install the dkms package first.

sudo dkms add ./rtl8188eu
sudo dkms build 8188eu/1.0
sudo dkms install 8188eu/1.0
