패키지 설치

sudo apt-get update

sudo apt-get install bridge-utils hostapd hostap-utils dnsmasq iw

sudo apt-get install udhcpd

===========================
기존의 hostapd를 교체 - 랜카드 드라이버로 인하여 (호환되는 랜카드 드라이버찾아야함 - 첨부된것은 iptime U100N Mini)

wget http://www.daveconroy.com/wp3/wp-content/uploads/2013/07/hostapd.zip
unzip hostapd.zip

혹시라도 작동중일지도 모르는, hostapd를 정지시키고 교체합니다.
sudo service hostapd stop
sudo cp hostapd /usr/sbin/hostapd
