Hello luamiennam,
There seem to be issues with the standard driver on AUR, it was flagged out-of-date on 14-06-2017.
You could try the instructions in this post:
https://bbs.archlinux.org/viewtopic.php?id=217873. See the reply from meismarv, this is the interesting bit:
git clone https://github.com/Mange/rtl8192eu-linux-driver.git
make
make install
smodprobe 8192eu
You may need to install dkms to make it work. Try without first. The command to install it should be somthing like this (not 100% sure of the format, maybe someone can correct me):
pacman -Sy --force dkms --noconfirm
Most WiFi drivers have a configuration file which is used to set up the configurable options. But I am not sure of the location or content for the RTL8192EU.
You may break Rune by modifying the kernel in this way, make a backup/copy first!
