I'm using odroid-xu4 with dietpi OS. I wished to use TL-WN822N wifi device as a hotspot. So I installed a driver of rtl8192eu by using this https://github.com/Mange/rtl8192eu-linux-driver

It installed correctly. After I installed hostapd and dnsmasq for it to work as a hotspot , hostapd is not running. It is always showing "exited".

The ifconfig result:

The iwconfig result:

My lsusb result:

My lshw result:

M hostapd /etc/hostapd/hostapd.conf result:

my hostapd.conf file contains:

interface=wlan1


driver=nl80211


ssid=WiFi-TV1


hw_mode=g


channel=3


ieee80211n=1


wmm_enabled=1

macaddr_acl=0


ignore_broadcast_ssid=0

rsn_pairwise=CCMP

  • Thanks. Bear in mind not all combo of drivers/wifi sticks provide AP mode and monitor mode. That is a research that has to be done before buying one. – Rui F Ribeiro Apr 18 '18 at 14:33
  • This device works well in raspberrypi as a AP mode. It also works well in ubuntu 16.04.1 as a AP mode. @Rui F Riberiro – akash Apr 18 '18 at 14:36
