If you are still facing any problems or you want to +also use WPA1, then follow the instructions below. + +NOTE: The instructions below are only valid for Realtek adapters with 8192 chipset. + +## Before installation + +If you're using ArchLinux, run: + +``` +pacman -S base-devel linux-headers dkms git +pacman -R hostapd +``` + +If you're using Debian, Ubuntu, or any Debian-based distribution, run: + +``` +apt-get install build-essential linux-headers-generic dkms git +apt-get remove hostapd +apt-get build-dep hostapd +``` + +## Install driver + +The driver in the mainline of Linux kernel doesn't work well with the 8192 adapters. +For this reason you need to install the driver that is provided from Realtek. Their +driver can not be compiled with newer kernels, but since it was an open-source +release under GPL license some people were able to fixed it and make it compile. + +With the following commands you can install a fixed version of Realtek's driver: + +``` +git clone https://github.com/pvaret/rtl8192cu-fixes.git +dkms add rtl8192cu-fixes +dkms install 8192cu/1.9 +cp rtl8192cu-fixes/blacklist-native-rtl8192.conf /etc/modprobe.d +cp rtl8192cu-fixes/8192cu-disable-power-management.conf /etc/modprobe.d +``` + +After installation, unload the previous driver and load the new one, or just reboot. + +## Install hostapd + +Realtek's driver is using an old subsystem which is called `wireless-extensions` +(or `wext`). Hostapd works only with the new subsystem (which is called `nl80211`). +For this reason Realtek wrote a patch for hostapd. You can install it with the +following commands: + +If you have ArchLinux install [hostapd-rtl871xdrv](https://aur.archlinux.org/packages/hostapd-rtl871xdrv) +from AUR or just run: + +``` +yaourt -S hostapd-rtl871xdrv +``` + +If you're using any other distribution, run: + +``` +git clone https://github.com/pritambaral/hostapd-rtl871xdrv.git +wget http://w1.fi/releases/hostapd-2.2.tar.gz +tar zxvf hostapd-2.2.tar.gz +cd hostapd-2.2 +patch -p1 -i ../hostapd-rtl871xdrv/rtlxdrv.patch +cp ../hostapd-rtl871xdrv/driver_* src/drivers +cd hostapd +cp defconfig .config +echo CONFIG_DRIVER_RTW=y >> .config +make +make install +```
